+ Compression and other good stuff for Optimizing your
+ ISDN System.
+
+ To Use this Extensions you MUST HAVE THE NEWEST
+ ISDN4K-UTILS. You must have Version 3.1-Beta6 or
+ higher. Elsewhere you can not configure this Extensions.
+
+ WARNING ! THIS STUF IS NOT PRODUCTION RELEASE THE
+ FUNCTION ARE UNDER DEVELOPMENT. This ist BETA-CODE.
+ You can use it at you Own Risk.
+
+ For more Information on these Extensions take a look at
+ "linux/Documentation/isdn/dw-abc-extension-howto.txt or
+ Online at the Web "http://i4l.mediatronix.de"
+
+ Please Report Bugs to "mario@mediatronix.de" or
+ "delefw@isdn4linux.de"
+
+D-Channel-Callback with Channel in use check
+CONFIG_ISDN_WITH_ABC_CALLB
+ When a Interface is declared as an Callback Interface,
+ the Interface is checking that the other Side is not
+ Calling on the same time before the Interface is Dialing.
+
+ See "linux/Documentation/isdn/dw-abc-extension-howto.txt"
+ for more Information
+
+ In most case answer with "Yes" when you have Callback devices,
+ otherwise leave it "No"
+
+Outgoing-EAZ-Support
+CONFIG_ISDN_WITH_ABC_OUTGOING_EAZ
+ Enables the Feature to Define an other EAZ or MSN for
+ Outgoing calls on an Interface.
+
+ See "linux/Documentation/isdn/dw-abc-extension-howto.txt"
+ for more Information
+
+Least Cost Router Support
+CONFIG_ISDN_WITH_ABC_LCR_SUPPORT
+ This is the final Kernel Code for configuring an Least
+ Cost Router Softwarebased. The other Job is to do the
+ action in ISDNLOG. You need the ISDNLOG to use this
+ function. Currently the ISDNLOG have not the Support for
+ this Option.
+ So in most situations let the Option off.
+
+TCP keepalive detect and response
+CONFIG_ISDN_WITH_ABC_IPV4_TCP_KEEPALIVE
+ This Option works only with the TCP/IP V4. It enables
+ the Function that ISDN Devices are Answering TCP_KEEPALIVE Pakets
+ localy. So that TCP KEEPALIVE Pakets not longer takes the Line
+ open.
+
+Drop frames Sourceadresse is not Interfaceadress
+CONFIG_ISDN_WITH_ABC_IPV4_DYNADDR
+ This Option works only with the TCP/IP V4. It will allow only
+ the Transmitt of Pakets where the Sourceadresse is the Interface
+ adress. It is usefull when you have Lines with Dynamic IP.
+
+ See "linux/Documentation/isdn/dw-abc-extension-howto.txt"
+ for more Information
+
+Receive do not reset the Hanguptimer
+CONFIG_ISDN_WITH_ABC_RCV_NO_HUPTIMER
+ When you activate this option than the reiceive of pakets do
+ not reset the Hanguptimer. It is very usefull because if the
+ Paket vor your Network your Network generate an Response and
+ the Transmit is reseting the HUPTIMER. But when the Paket is
+ Rejected at your firewall your network generate no Response
+ and no Sendtraffic is generated. So in this case there is no
+ need to Reset the Huptimer because you have only received Data.
+ With that option only Transmitted Data/Pakets will reset the
+ HUPTIMER.
+
+Support of (device-channel) and Binding Groups
+CONFIG_ISDN_WITH_ABC_ICALL_BIND
+ This Option enables the Feature to Bind logical ISDN Interfaces
+ to an prefered ISDN Card or ISDN Card plus Channel. So you have
+ the Chance to keep Channels exclusively for one (or more)
+ Connection. Very usefull when you have more channels and Use
+ Calling Line Identification, because you can organize that your
+ call is going out over the Line with the right EAZ for the CLI.
+
+Skip channel if used external (Dial Only)
+CONFIG_ISDN_WITH_ABC_CH_EXTINUSE
+ When you have more than One ISDN Card in your System and you
+ will Dialout with an Interface you can become the Situation
+ that an External Device such a Telephone or Fax is Using the
+ B-Channels. Normaly ISDN4Linux does not detect this Situation
+ and dial everytime of the "External Busy" line out. With this
+ Option Enabled the I4L will detect that he can not dialout on
+ This Card and dial over the next Card out.
+
+ See "linux/Documentation/isdn/dw-abc-extension-howto.txt"
+ for more Information
+
+Interface autodisable if Config error
+CONFIG_ISDN_WITH_ABC_CONN_ERROR
+ This Option will detect an Device which generate Telephone
+ Cost but does not Function correctly because there are
+ Configerrors on one of the Site. In this Situation the
+ Interface will be marked as Unsuably for some time to do
+ not call every time this Site.

(at your option) any later version.
This program is distributed in the hope that it will be useful,
but WITHOUT ANY WARRANTY; without even the implied warranty of
MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the
GNU General Public License for more details.
However, if you wish to modify the HiSax sources, please note the following:
HiSax has passed the ITU approval test suite with ELSA Quickstep ISDN cards
and Eicon Technology Diva 2.01 PCI card.
The certification is only valid for the combination of the tested software
version and the tested hardware. Any changes to the HiSax source code may
therefore affect the certification.
If you change the main files of the HiSax ISDN stack, the certification will
become invalid. Because in most countries it is illegal to connect
unapproved ISDN equipment to the public network, I have to guarantee that
changes in HiSax do not affect the certification.
In order to make a valid certification apparent to the user, I have built in
some validation checks that are made during the make process. The HiSax main
files are protected by md5 checksums and the md5sum file is pgp signed by
myself:
KeyID 1024/FF992F6D 1997/01/16 Karsten Keil <kkeil@suse.de>
Key fingerprint = 92 6B F7 58 EE 86 28 C8 C4 1A E6 DC 39 89 F2 AA
Only if the checksums are OK, and the signature of the file
"drivers/isdn/hisax/md5sums.asc" match, is the certification valid; a
message confirming this is then displayed during the hisax init process.
The affected files are:

Please send any changes, bugfixes and patches to me rather than implementing
them directly into the HiSax sources.
This does not reduce your rights granted by the GNU General Public License.
If you wish to change the sources, go ahead; but note that then the
certification is invalid even if you use one of the approved cards.

Description of the Interface between Linklevel and Hardwarelevel
of isdn4linux:
The Communication between Linklevel (LL) and Hardwarelevel (HL)
is based on the struct isdn_if (defined in isdnif.h).
An HL-driver can register itself at LL by calling the function
register_isdn() with a pointer to that struct. Prior to that, it has
to preset some of the fields of isdn_if. The LL sets the rest of
the fields. All further communication is done via callbacks using
the function-pointers defined in isdn_if.
Changes/Version numbering:
During development of the ISDN subsystem, several changes have been
made to the interface. Before it went into kernel, the package
had a unique version number. The last version, distributed separately
was 0.7.4. When the subsystem went into kernel, every functional unit
got a separate version number. These numbers are shown at initialization,
separated by slashes:
c.c/t.t/n.n/p.p/a.a/v.v
where
c.c is the revision of the common code.
t.t is the revision of the tty related code.
n.n is the revision of the network related code.
p.p is the revision of the ppp related code.
a.a is the revision of the audio related code.
v.v is the revision of the V.110 related code.
Changes in this document are marked with '***CHANGEx' where x representing
the version number. If that number starts with 0, it refers to the old,
separately distributed package. If it starts with one of the letters
above, it refers to the revision of the corresponding module.
***CHANGEIx refers to the revision number of the isdnif.h
1. Description of the fields of isdn_if:
int channels;
This field has to be set by the HL-driver to the number of channels
supported prior to calling register_isdn(). Upon return of the call,
the LL puts an id there, which has to be used by the HL-driver when
invoking the other callbacks.
int maxbufsize;
***CHANGE0.6: New since this version.
Also to be preset by the HL-driver. With this value the HL-driver
tells the LL the maximum size of a data-packet it will accept.
unsigned long features;
To be preset by the HL-driver. Using this field, the HL-driver
announces the features supported. At the moment this is limited to
report the supported layer2 and layer3-protocols. For setting this
field the constants ISDN_FEATURE..., declared in isdnif.h have to be
used.
***CHANGE0.7.1: The line type (1TR6, EDSS1) has to be set.
unsigned short hl_hdrlen;
***CHANGE0.7.4: New field.
To be preset by the HL-driver, if it supports sk_buff's. The driver
should put here the amount of additional space needed in sk_buff's for
its internal purposes. Drivers not supporting sk_buff's should
initialize this field to 0.
void (*rcvcallb_skb)(int, int, struct sk_buff *)
***CHANGE0.7.4: New field.
This field will be set by LL. The HL-driver delivers received data-
packets by calling this function. Upon calling, the HL-driver must
already have its private data pulled off the head of the sk_buff.
Parameter:
int driver-Id
int Channel-number locally to the driver. (starting with 0)
struct sk_buff * Pointer to sk_buff, containing received data.
int (*statcallb)(isdn_ctrl*);
This field will be set by LL. This function has to be called by the
HL-driver for signaling status-changes or other events to the LL.
Parameter:
isdn_ctrl*
The struct isdn_ctrl also defined in isdn_if. The exact meanings of its
fields are described together with the descriptions of the possible
events. Here is only a short description of the fields:
driver = driver Id.
command = event-type. (one of the constants ISDN_STAT_...)
arg = depends on event-type.
num = depends on event-type.
Returnvalue:
0 on success, else -1
int (*command)(isdn_ctrl*);
This field has to be preset by the HL-driver. It points to a function,
to be called by LL to perform functions like dialing, B-channel
setup, etc. The exact meaning of the parameters is described with the
descriptions of the possible commands.
Parameter:
isdn_ctrl*
driver = driver-Id
command = command to perform. (one of the constants ISDN_CMD_...)
arg = depends on command.
num = depends on command.
Returnvalue:
>=0 on success, else error-code (-ENODEV etc.)
int (*writebuf_skb)(int, int, int, struct sk_buff *)
***CHANGE0.7.4: New field.
***CHANGEI.1.21: New field.
This field has to be preset by the HL-driver. The given function will
be called by the LL for delivering data to be send via B-Channel.
Parameter:
int driver-Id ***CHANGE0.7.4: New parameter.
int channel-number locally to the HL-driver. (starts with 0)
int ack ***ChangeI1.21: New parameter
If this is !0, the driver has to signal the delivery
by sending an ISDN_STAT_BSENT. If this is 0, the driver
MUST NOT send an ISDN_STAT_BSENT.
struct sk_buff * Pointer to sk_buff containing data to be send via
B-channel.
Returnvalue:
Length of data accepted on success, else error-code (-EINVAL on
oversized packets etc.)
int (*writecmd)(u_char*, int, int, int, int);
This field has to be preset by the HL-driver. The given function will be
called to perform write-requests on /dev/isdnctrl (i.e. sending commands
to the card) The data-format is hardware-specific. This function is
intended for debugging only. It is not necessary for normal operation
and never will be called by the tty-emulation- or network-code. If
this function is not supported, the driver has to set NULL here.
Parameter:
u_char* pointer to data.
int length of data.
int flag: 0 = call from within kernel-space. (HL-driver must use
memcpy, may NOT use schedule())
1 = call from user-space. (HL-driver must use
memcpy_fromfs, use of schedule() allowed)
int driver-Id.
int channel-number locally to the HL-driver. (starts with 0)
***CHANGEI1.14: The driver-Id and channel-number are new since this revision.
Returnvalue:
Length of data accepted on success, else error-code (-EINVAL etc.)
int (*readstat)(u_char*, int, int, int, int);
This field has to be preset by the HL-driver. The given function will be
called to perform read-requests on /dev/isdnctrl (i.e. reading replies
from the card) The data-format is hardware-specific. This function is
intended for debugging only. It is not necessary for normal operation
and never will be called by the tty-emulation- or network-code. If
this function is not supported, the driver has to set NULL here.
Parameter:
u_char* pointer to data.
int length of data.
int flag: 0 = call from within kernel-space. (HL-driver must use
memcpy, may NOT use schedule())
1 = call from user-space. (HL-driver must use
memcpy_fromfs, use of schedule() allowed)
int driver-Id.
int channel-number locally to the HL-driver. (starts with 0)
***CHANGEI1.14: The driver-Id and channel-number are new since this revision.
Returnvalue:
Length of data on success, else error-code (-EINVAL etc.)
char id[20];
***CHANGE0.7: New since this version.
This string has to be preset by the HL-driver. Its purpose is for
identification of the driver by the user. Eg.: it is shown in the
status-info of /dev/isdninfo. Furthermore it is used as Id for binding
net-interfaces to a specific channel. If a string of length zero is
given, upon return, isdn4linux will replace it by a generic name. (line0,
line1 etc.) It is recommended to make this string configurable during
module-load-time. (copy a global variable to this string.) For doing that,
modules 1.2.8 or newer are necessary.
2. Description of the commands, a HL-driver has to support:
All commands will be performed by calling the function command() described
above from within the LL. The field command of the struct-parameter will
contain the desired command, the field driver is always set to the
appropriate driver-Id.
Until now, the following commands are defined:
***CHANGEI1.34: The parameter "num" has been replaced by a union "parm" containing
the old "num" and a new setup_type struct used for ISDN_CMD_DIAL
and ISDN_STAT_ICALL callback.

This command is intended for performing ioctl-calls for configuring
hardware or similar purposes (setting port-addresses, loading firmware
etc.) For this purpose, in the LL all ioctl-calls with an argument
>= IIOCDRVCTL (0x100) will be handed transparently to this
function after subtracting 0x100 and placing the result in arg.
Example:
If a userlevel-program calls ioctl(0x101,...) the function gets
called with the field command set to 1.
Parameter:
driver = driver-Id.

With this call, the HL-driver signals the LL to disable or enable the
use of supplied channel and driver.
The call may be used to reduce the available number of B-channels after
loading the driver. The LL has to ignore a disabled channel when searching
for free channels. The HL driver itself never delivers STAT callbacks for
disabled channels.
The LL returns a nonzero code if the operation was not successfull or the
selected channel is actually regarded as busy.
Parameter:
driver = driver-Id
command = ISDN_STAT_DISCH

Description of the fax-subinterface between linklevel and hardwarelevel of
isdn4linux.
The communication between linklevel (LL) and harwarelevel (HL) for fax
is based on the struct T30_s (defined in isdnif.h).
This struct is allocated in the LL.
In order to use fax, the LL provides the pointer to this struct with the
command ISDN_CMD_SETL3 (parm.fax). This pointer expires in case of hangup
and when a new channel to a new connection is assigned.
Data handling:
In send-mode the HL-driver has to handle the <DLE> codes and the bit-order
conversion by itself.
In receive-mode the LL-driver takes care of the bit-order conversion
(specified by +FBOR)
Structure T30_s description:
This structure stores the values (set by AT-commands), the remote-
capability-values and the command-codes between LL and HL.
If the HL-driver receives ISDN_CMD_FAXCMD, all needed information
is in this struct set by the LL.
To signal information to the LL, the HL-driver has to set the
the parameters and use ISDN_STAT_FAXIND.
(Please refer to INTERFACE)
Structure T30_s:
All members are 8-bit unsigned (__u8)
- resolution
- rate
- width
- length
- compression
- ecm
- binary
- scantime
- id[]
Local faxmachine's parameters, set by +FDIS, +FDCS, +FLID, ...
- r_resolution

- r_width
- r_length
- r_compression
- r_ecm
- r_binary
- r_scantime
- r_id[]
Remote faxmachine's parameters. To be set by HL-driver.
- phase
Defines the actual state of fax connection. Set by HL or LL
depending on progress and type of connection.
If the phase changes because of an AT command, the LL driver
changes this value. Otherwise the HL-driver takes care of it, but
only neccessary on call establishment (from IDLE to PHASE_A).
(one of the constants ISDN_FAX_PHASE_[IDLE,A,B,C,D,E])
- direction
Defines outgoing/send or incoming/receive connection.
(ISDN_TTY_FAX_CONN_[IN,OUT])
- code
Commands from LL to HL; possible constants :
ISDN_TTY_FAX_DR signals +FDR command to HL
ISDN_TTY_FAX_DT signals +FDT command to HL
ISDN_TTY_FAX_ET signals +FET command to HL
Other than that the "code" is set with the hangup-code value at
the end of connection for the +FHNG message.
- r_code
Commands from HL to LL; possible constants :
ISDN_TTY_FAX_CFR output of +FCFR message.
ISDN_TTY_FAX_RID output of remote ID set in r_id[]
(+FCSI/+FTSI on send/receive)
ISDN_TTY_FAX_DCS output of +FDCS and CONNECT message,
switching to phase C.
ISDN_TTY_FAX_ET signals end of data,
switching to phase D.
ISDN_TTY_FAX_FCON signals the established, outgoing connection,
switching to phase B.
ISDN_TTY_FAX_FCON_I signals the established, incoming connection,
switching to phase B.
ISDN_TTY_FAX_DIS output of +FDIS message and values.
ISDN_TTY_FAX_SENT signals that all data has been sent
and <DLE><ETX> is acknowledged,
OK message will be sent.
ISDN_TTY_FAX_PTS signals a msg-confirmation (page sent successful),
depending on fet value:
0: output OK message (more pages follow)
1: switching to phase B (next document)
ISDN_TTY_FAX_TRAIN_OK output of +FDCS and OK message (for receive mode).
ISDN_TTY_FAX_EOP signals end of data in receive mode,
switching to phase D.
ISDN_TTY_FAX_HNG output of the +FHNG and value set by code and
OK message, switching to phase E.
- badlin
Value of +FBADLIN
- badmul
Value of +FBADMUL
- bor
Value of +FBOR

README for the ISDN-subsystem
1. Preface
1.1 Introduction
This README describes how to set up and how to use the different parts
of the ISDN-subsystem.
For using the ISDN-subsystem, some additional userlevel programs are
necessary. Those programs and some contributed utilities are available
at
ftp.isdn4linux.de
/pub/isdn4linux/isdn4k-utils-<VersionNumber>.tar.gz
We also have set up a mailing-list:
The isdn4linux-project originates in Germany, and therefore by historical
reasons, the mailing-list's primary language is german. However mails
written in english have been welcome all the time.

1.1 Technical details
In the following Text, the terms MSN and EAZ are used.
MSN is the abbreviation for (M)ultiple(S)ubscriber(N)umber, and applies
to Euro(EDSS1)-type lines. Usually it is simply the phone number.
EAZ is the abbreviation of (E)ndgeraete(A)uswahl(Z)iffer and
applies to German 1TR6-type lines. This is a one-digit string,
simply appended to the base phone number
The internal handling is nearly identical, so replace the appropriate
term to that one, which applies to your local ISDN-environment.
When the link-level-module isdn.o is loaded, it supports up to 16
low-level-modules with up to 64 channels. (The number 64 is arbitrarily
chosen and can be configured at compile-time --ISDN_MAX in isdn.h).
A low-level-driver can register itself through an interface (which is
defined in isdnif.h) and gets assigned a slot.
The following char-devices are made available for each channel:
A raw-control-device with the following functions:
write: raw D-channel-messages (format: depends on driver).
read: raw D-channel-messages (format: depends on driver).
ioctl: depends on driver, i.e. for the ICN-driver, the base-address of
the ports and the shared memory on the card can be set and read
also the boot-code and the protocol software can be loaded into
the card.
O N L Y !!! for debugging (no locking against other devices):
One raw-data-device with the following functions:
write: data to B-channel.
read: data from B-channel.
In addition the following devices are made available:
128 tty-devices (64 cuix and 64 ttyIx) with integrated modem-emulator:
The functionality is almost the same as that of a serial device
(the line-discs are handled by the kernel), which lets you run
SLIP, CSLIP and asynchronous PPP through the devices. We have tested
Seyon, minicom, CSLIP (uri-dip) PPP, mgetty, XCept and Hylafax.
The modem-emulation supports the following:
1.3.1 Commands:
ATA Answer incoming call.
ATD<No.> Dial, the number may contain:
[0-9] and [,#.*WPT-S]
the latter are ignored until 'S'.
The 'S' must precede the number, if
the line is a SPV (German 1TR6).
ATE0 Echo off.
ATE1 Echo on (default).
ATH Hang-up.
ATH1 Off hook (ignored).
ATH0 Hang-up.
ATI Return "ISDN for Linux...".
ATI0 "
ATI1 "
ATI2 Report of last connection.
ATO On line (data mode).
ATQ0 Enable result codes (default).
ATQ1 Disable result codes (default).
ATSx=y Set register x to y.
ATSx? Show contents of register x.
ATV0 Numeric responses.
ATV1 English responses (default).
ATZ Load registers and EAZ/MSN from Profile.
AT&Bx Set Send-Packet-size to x (max. 4000)
The real packet-size may be limited by the
low-level-driver used. e.g. the HiSax-Module-
limit is 2000. You will get NO Error-Message,
if you set it to higher values, because at the
time of giving this command the corresponding
driver may not be selected (see "Automatic
Assignment") however the size of outgoing packets
will be limited correctly.
AT&D0 Ignore DTR
AT&D2 DTR-low-edge: Hang up and return to
command mode (default).
AT&D3 Same as AT&D2 but also resets all registers.
AT&Ex Set the EAZ/MSN for this channel to x.
AT&F Reset all registers and profile to "factory-defaults"
AT&Lx Set list of phone numbers to listen on. x is a
list of wildcard patterns separated by semicolon.
If this is set, it has precedence over the MSN set
by AT&E.
AT&Rx Select V.110 bitrate adaption.
This command enables V.110 protocol with 9600 baud
(x=9600), 19200 baud (x=19200) or 38400 baud
(x=38400). A value of x=0 disables V.110 switching
back to default X.75. This command sets the following
Registers:
Reg 14 (Layer-2 protocol):
x = 0: 0
x = 9600: 7
x = 19200: 8
x = 38400: 9
Reg 18.2 = 1
Reg 19 (Additional Service Indicator):
x = 0: 0
x = 9600: 197
x = 19200: 199
x = 38400: 198
Note on value in Reg 19:
There is _NO_ common convention for 38400 baud.
The value 198 is choosen arbitrarily. Users
_MUST_ negotiate this value before establishing
a connection.
AT&Sx Set window-size (x = 1..8) (not yet implemented)
AT&V Show all settings.
AT&W0 Write registers and EAZ/MSN to profile. See also
iprofd (5.c in this README).
AT&X0 BTX-mode and T.70-mode off (default)
AT&X1 BTX-mode on. (S13.1=1, S13.5=0 S14=0, S16=7, S18=7, S19=0)
AT&X2 T.70-mode on. (S13.1=1, S13.5=1, S14=0, S16=7, S18=7, S19=0)
AT+Rx Resume a suspended call with CallID x (x = 1,2,3...)
AT+Sx Suspend a call with CallID x (x = 1,2,3...)
For voice-mode commands refer to README.audio
1.3.2 Escape sequence:
During a connection, the emulation reacts just like
a normal modem to the escape sequence <DELAY>+++<DELAY>.
(The escape character - default '+' - can be set in the
register 2).
The DELAY must at least be 1.5 seconds long and delay
between the escape characters must not exceed 0.5 seconds.
1.3.3 Registers:
Nr. Default Description
0 0 Answer on ring number.
(no auto-answer if S0=0).
1 0 Count of rings.
2 43 Escape character.
(a value >= 128 disables the escape sequence).

or to be used on dialout:
Bit 0: Service 1 (audio) when set.
Bit 1: Service 5 (BTX) when set.
Bit 2: Service 7 (data) when set.
Note: It is possible to set more than one
bit. In this case, on incoming calls
the selected services are accepted,
and if the service is "audio", the
Layer-2-protocol is automatically
changed to 4 regardless of the setting
of register 14. On outgoing calls,
the most significant 1-bit is chosen to
select the outgoing service octet.

Bit 0: 0 = Add CPN to RING message off
1 = Add CPN to RING message on
Bit 1: 0 = Add CPN to FCON message off
1 = Add CPN to FCON message on
Last but not least a (at the moment fairly primitive) device to request
the line-status (/dev/isdninfo) is made available.
Automatic assignment of devices to lines:
All inactive physical lines are listening to all EAZs for incoming
calls and are NOT assigned to a specific tty or network interface.
When an incoming call is detected, the driver looks first for a network
interface and then for an opened tty which:
1. is configured for the same EAZ.
2. has the same protocol settings for the B-channel.
3. (only for network interfaces if the security flag is set)
contains the caller number in its access list.
4. Either the channel is not bound exclusively to another Net-interface, or
it is bound AND the other checks apply to exactly this interface.
(For usage of the bind-features, refer to the isdnctrl-man-page)
Only when a matching interface or tty is found is the call accepted
and the "connection" between the low-level-layer and the link-level-layer
is established and kept until the end of the connection.
In all other cases no connection is established. Isdn4linux can be
configured to either do NOTHING in this case (which is useful, if
other, external devices with the same EAZ/MSN are connected to the bus)
or to reject the call actively. (isdnctrl busreject ...)
For an outgoing call, the inactive physical lines are searched.
The call is placed on the first physical line, which supports the
requested protocols for the B-channel. If a net-interface, however
is pre-bound to a channel, this channel is used directly.
This makes it possible to configure several network interfaces and ttys
for one EAZ, if the network interfaces are set to secure operation.
If an incoming call matches one network interface, it gets connected to it.
If another incoming call for the same EAZ arrives, which does not match
a network interface, the first tty gets a "RING" and so on.
2 System prerequisites:
ATTENTION!
Always use the latest module utilities. The current version is
named in Documentation/Changes. Some old versions of insmod
are not capable of setting the driver-Ids correctly.
3. Lowlevel-driver configuration.
Configuration depends on how the drivers are built. See the
README.<yourDriver> for information on driver-specific setup.
4. Device-inodes
The major and minor numbers and their names are described in
Documentation/devices.txt. The major numbers are:
43 for the ISDN-tty's.
44 for the ISDN-callout-tty's.
45 for control/info/debug devices.
5. Application
a) For some card-types, firmware has to be loaded into the cards, before
proceeding with device-independent setup. See README.<yourDriver>
for how to do that.
b) If you only intend to use ttys, you are nearly ready now.
c) If you want to have really permanent "Modem"-settings on disk, you
can start the daemon iprofd. Give it a path to a file at the command-
line. It will store the profile-settings in this file every time
an AT&W0 is performed on any ISDN-tty. If the file already exists,
all profiles are initialized from this file. If you want to unload
any of the modules, kill iprofd first.
d) For networking, continue: Create an interface:
isdnctrl addif isdn0
e) Set the EAZ (or MSN for Euro-ISDN):
isdnctrl eaz isdn0 2
(For 1TR6 a single digit is allowed, for Euro-ISDN the number is your
real MSN e.g.: Phone-Number)
f) Set the number for outgoing calls on the interface:
isdnctrl addphone isdn0 out 1234567
... (this can be executed more than once, all assigned numbers are
tried in order)
and the number(s) for incoming calls:
isdnctrl addphone isdn0 in 1234567
g) Set the timeout for hang-up:
isdnctrl huptimeout isdn0 <timeout_in_seconds>
h) additionally you may activate charge-hang-up (= Hang up before
next charge-info, this only works, if your isdn-provider transmits
the charge-info during and after the connection):
isdnctrl chargehup isdn0 on
i) Set the dial mode of the interface:
isdnctrl dialmode isdn0 auto
"off" means that you (or the system) cannot make any connection
(neither incoming or outgoing connections are possible). Use
this if you want to be sure that no connections will be made.
"auto" means that the interface is in auto-dial mode, and will
attempt to make a connection whenever a network data packet needs
the interface's link. Note that this can cause unexpected dialouts,
and lead to a high phone bill! Some daemons or other pc's that use
this interface can cause this.
Incoming connections are also possible.
"manual" is a dial mode created to prevent the unexpected dialouts.
In this mode, the interface will never make any connections on its
own. You must explicitly initiate a connection with "isdnctrl dial
isdn0". However, after an idle time of no traffic as configured for
the huptimeout value with isdnctrl, the connection _will_ be ended.
If you don't want any automatic hangup, set the huptimeout value to 0.
"manual" is the default.
j) Setup the interface with ifconfig as usual, and set a route to it.
k) (optional) If you run X11 and have Tcl/Tk-wish version 4.0, you can use
the script tools/tcltk/isdnmon. You can add actions for line-status
changes. See the comments at the beginning of the script for how to
do that. There are other tty-based tools in the tools-subdirectory
contributed by Michael Knigge (imon), Volker Götz (imontty) and
Andreas Kool (isdnmon).
l) For initial testing, you can set the verbose-level to 2 (default: 0).
Then all incoming calls are logged, even if they are not addressed
to one of the configured net-interfaces:
isdnctrl verbose 2
Now you are ready! A ping to the set address should now result in an
automatic dial-out (look at syslog kernel-messages).
The phone numbers and EAZs can be assigned at any time with isdnctrl.
You can add as many interfaces as you like with addif following the
directions above. Of course, there may be some limitations. But we have
tested as many as 20 interfaces without any problem. However, if you
don't give an interface name to addif, the kernel will assign a name
which starts with "eth". The number of "eth"-interfaces is limited by
the kernel.
5. Additional options for isdnctrl:
"isdnctrl secure <InterfaceName> on"
Only incoming calls, for which the caller-id is listed in the access
list of the interface are accepted. You can add caller-id's With the
command "isdnctrl addphone <InterfaceName> in <caller-id>"
Euro-ISDN does not transmit the leading '0' of the caller-id for an
incoming call, therefore you should configure it accordingly.
If the real number for the dialout e.g. is "09311234567" the number
to configure here is "9311234567". The pattern-match function
works similar to the shell mechanism.
? one arbitrary digit
* zero or arbitrary many digits
[123] one of the digits in the list
[1-5] one digit between '1' and '5'
a '^' as the first character in a list inverts the list
"isdnctrl secure <InterfaceName> off"
Switch off secure operation (default).
"isdnctrl ihup <InterfaceName> [on|off]"
Switch the hang-up-timer for incoming calls on or off.
"isdnctrl eaz <InterfaceName>"
Returns the EAZ of an interface.
"isdnctrl delphone <InterfaceName> in|out <number>"
Deletes a number from one of the access-lists of the interface.
"isdnctrl delif <InterfaceName>"
Removes the interface (and possible slaves) from the kernel.
(You have to unregister it with "ifconfig <InterfaceName> down" before).
"isdnctrl callback <InterfaceName> [on|off]"
Switches an interface to callback-mode. In this mode, an incoming call
will be rejected and after this the remote-station will be called. If
you test this feature by using ping, some routers will re-dial very
quickly, so that the callback from isdn4linux may not be recognized.
In this case use ping with the option -i <sec> to increase the interval
between echo-packets.
"isdnctrl cbdelay <InterfaceName> [seconds]"
Sets the delay (default 5 sec) between an incoming call and start of
dialing when callback is enabled.
"isdnctrl cbhup <InterfaceName> [on|off]"
This enables (default) or disables an active hangup (reject) when getting an
incoming call for an interface which is configured for callback.
"isdnctrl encap <InterfaceName> <EncapType>"
Selects the type of packet-encapsulation. The encapsulation can be changed
only while an interface is down.
At the moment the following values are supported:
rawip (Default) Selects raw-IP-encapsulation. This means, MAC-headers
are stripped off.
ip IP with type-field. Same as IP but the type-field of the MAC-header
is preserved.
x25iface X.25 interface encapsulation (first byte semantics as defined in
../networking/x25-iface.txt). Use this for running the linux
X.25 network protocol stack (AF_X25 sockets) on top of isdn.
cisco-h A special-mode for communicating with a Cisco, which is configured
to do "hdlc"
ethernet No stripping. Packets are sent with full MAC-header.
The Ethernet-address of the interface is faked, from its
IP-address: fc:fc:i1:i2:i3:i4, where i1-4 are the IP-addr.-values.
syncppp Synchronous PPP
uihdlc HDLC with UI-frame-header (for use with DOS ISPA, option -h1)
NOTE: x25iface encapsulation is currently experimental. Please
read README.x25 for further details
Watching packets, using standard-tcpdump will fail for all encapsulations
except ethernet because tcpdump does not know how to handle packets
without MAC-header. A patch for tcpdump is included in the utility-package
mentioned above.
"isdnctrl l2_prot <InterfaceName> <L2-ProtocolName>"
Selects a layer-2-protocol.
(With the ICN-driver and the HiSax-driver, "x75i" and "hdlc" is available.
With other drivers, "x75ui", "x75bui", "x25dte", "x25dce" may be
possible too. See README.x25 for x25 related l2 protocols.)
isdnctrl l3_prot <InterfaceName> <L3-ProtocolName>
The same for layer-3. (At the moment only "trans" is allowed)
"isdnctrl list <InterfaceName>"
Shows all parameters of an interface and the charge-info.
Try "all" as the interface name.
"isdnctrl hangup <InterfaceName>"
Forces hangup of an interface.
"isdnctrl bind <InterfaceName> <DriverId>,<ChannelNumber> [exclusive]"
If you are using more than one ISDN card, it is sometimes necessary to
dial out using a specific card or even preserve a specific channel for
dialout of a specific net-interface. This can be done with the above
command. Replace <DriverId> by whatever you assigned while loading the
module. The <ChannelNumber> is counted from zero. The upper limit
depends on the card used. At the moment no card supports more than
2 channels, so the upper limit is one.
"isdnctrl unbind <InterfaceName>"
unbinds a previously bound interface.
"isdnctrl busreject <DriverId> on|off"
If switched on, isdn4linux replies a REJECT to incoming calls, it
cannot match to any configured interface.
If switched off, nothing happens in this case.
You normally should NOT enable this feature, if the ISDN adapter is not
the only device connected to the S0-bus. Otherwise it could happen that
isdn4linux rejects an incoming call, which belongs to another device on
the bus.
"isdnctrl addslave <InterfaceName> <SlaveName>
Creates a slave interface for channel-bundling. Slave interfaces are
not seen by the kernel, but their ISDN-part can be configured with
isdnctrl as usual. (Phone numbers, EAZ/MSN, timeouts etc.) If more
than two channels are to be bundled, feel free to create as many as you
want. InterfaceName must be a real interface, NOT a slave. Slave interfaces
start dialing, if the master interface resp. the previous slave interface
has a load of more than 7000 cps. They hangup if the load goes under 7000
cps, according to their "huptimeout"-parameter.
"isdnctrl sdelay <InterfaceName> secs."
This sets the minimum time an Interface has to be fully loaded, until
it sends a dial-request to its slave.
"isdnctrl dial <InterfaceName>"
Forces an interface to start dialing even if no packets are to be
transferred.
"isdnctrl mapping <DriverId> MSN0,MSN1,MSN2,...MSN9"
This installs a mapping table for EAZ<->MSN-mapping for a single line.
Missing MSN's have to be given as "-" or can be omitted, if at the end
of the commandline.
With this command, it's now possible to have an interface listening to
mixed 1TR6- and Euro-Type lines. In this case, the interface has to be
configured to a 1TR6-type EAZ (one digit). The mapping is also valid
for tty-emulation. Seen from the interface/tty-level the mapping
CAN be used, however it's possible to use single tty's/interfaces with
real MSN's (more digits) also, in which case the mapping will be ignored.
Here is an example:
You have a 1TR6-type line with base-nr. 1234567 and a Euro-line with
MSN's 987654, 987655 and 987656. The DriverId for the Euro-line is "EURO".
isdnctrl mapping EURO -,987654,987655,987656,-,987655
...
isdnctrl eaz isdn0 1 # listen on 12345671(1tr6) and 987654(euro)
...
isdnctrl eaz isdn1 4 # listen on 12345674(1tr6) only.
...
isdnctrl eaz isdn2 987654 # listen on 987654(euro) only.
Same scheme is used with AT&E... at the tty's.
6. If you want to write a new low-level-driver, you are welcome.
The interface to the link-level-module is described in the file INTERFACE.
If the interface should be expanded for any reason, don't do it
on your own, send me a mail containing the proposed changes and
some reasoning about them.
If other drivers will not be affected, I will include the changes
in the next release.
For developers only, there is a second mailing-list. Write to me
(fritz@isdn4linux.de), if you want to join that list.
Have fun!

If you know other passive cards with the Siemens chipset, please let me know.
To use the PNP cards you need the isapnptools.
You can combine any card, if there is no conflict between the ressources
(io, mem, irq).
Configuring the driver
----------------------
The HiSax driver can either be built directly into the kernel or as a module.
It can be configured using the command line feature while loading the kernel
with LILO or LOADLIN or, if built as a module, using insmod/modprobe with
parameters.
There is also some config needed before you compile the kernel and/or
modules. It is included in the normal "make [menu]config" target at the
kernel. Don't forget it, especially to select the right D-channel protocol.
Please note: All PnP cards need to be configured with isapnp and will work
only with the HiSax driver used as a module.
a) when built as a module
-------------------------
insmod/modprobe hisax.o \
io=iobase irq=IRQ mem=membase type=card_type \
protocol=D_channel_protocol id=idstring
or, if several cards are installed:
insmod/modprobe hisax.o \
io=iobase1,iobase2,... irq=IRQ1,IRQ2,... mem=membase1,membase2,... \
type=card_type1,card_type2,... \
protocol=D_channel_protocol1,D_channel_protocol2,... \
id=idstring1%idstring2 ...
where "iobaseN" represents the I/O base address of the Nth card, "membaseN"
the memory base address of the Nth card, etc.
The reason for the delimiter "%" being used in the idstrings is that ","
won't work with the current modules package.
The parameters may be specified in any order. For example, the "io"
parameter may precede the "irq" parameter, or vice versa. If several
cards are installed, the ordering within the comma separated parameter
lists must of course be consistent.
Only parameters applicable to the card type need to be specified. For
example, the Teles 16.3 card is not memory-mapped, so the "mem"
parameter may be omitted for this card. Sometimes it may be necessary
to specify a dummy parameter, however. This is the case when there is
a card of a different type later in the list that needs a parameter
which the preceding card does not. For instance, if a Teles 16.0 card
is listed after a Teles 16.3 card, a dummy memory base parameter of 0
must be specified for the 16.3. Instead of a dummy value, the parameter
can also be skipped by simply omitting the value. For example:
mem=,0xd0000. See example 6 below.
The parameter for the D-Channel protocol may be omitted if you selected the
correct one during kernel config. Valid values are "1" for German 1TR6,
"2" for EDSS1 (Euro ISDN) and "3" for leased lines (no D-Channel).
The Creatix/Teles PnP cards use io1= and io2= instead of io= for specifying
the I/O addresses of the ISAC and HSCX chips, respectively.

Running the driver
------------------
When you insmod isdn.o and hisax.o (or with the in-kernel version, during
boot time), a few lines should appear in your syslog. Look for something like:
Apr 13 21:01:59 kke01 kernel: HiSax: Driver for Siemens chip set ISDN cards
Apr 13 21:01:59 kke01 kernel: HiSax: Version 2.9
Apr 13 21:01:59 kke01 kernel: HiSax: Revisions 1.14/1.9/1.10/1.25/1.8
Apr 13 21:01:59 kke01 kernel: HiSax: Total 1 card defined
Apr 13 21:01:59 kke01 kernel: HiSax: Card 1 Protocol EDSS1 Id=HiSax1 (0)
Apr 13 21:01:59 kke01 kernel: HiSax: Elsa driver Rev. 1.13
...
Apr 13 21:01:59 kke01 kernel: Elsa: PCF-Pro found at 0x360 Rev.:C IRQ 10
Apr 13 21:01:59 kke01 kernel: Elsa: timer OK; resetting card
Apr 13 21:01:59 kke01 kernel: Elsa: HSCX version A: V2.1 B: V2.1
Apr 13 21:01:59 kke01 kernel: Elsa: ISAC 2086/2186 V1.1
...
Apr 13 21:01:59 kke01 kernel: HiSax: DSS1 Rev. 1.14
Apr 13 21:01:59 kke01 kernel: HiSax: 2 channels added
This means that the card is ready for use.
Cabling problems or line-downs are not detected, and only some ELSA cards can
detect the S0 power.
Remember that, according to the new strategy for accessing low-level drivers
from within isdn4linux, you should also define a driver ID while doing
insmod: Simply append hisax_id=<SomeString> to the insmod command line. This
string MUST NOT start with a digit or a small 'x'!
At this point you can run a 'cat /dev/isdnctrl0' and view debugging messages.
At the moment, debugging messages are enabled with the hisaxctrl tool:
hisaxctrl <DriverId> DebugCmd <debugging_flags>
<DriverId> default is HiSax, if you didn't specify one.
DebugCmd is 1 for generic debugging
11 for layer 1 development debugging
13 for layer 3 development debugging
where <debugging_flags> is the integer sum of the following debugging
options you wish enabled:
With DebugCmd set to 1:
0x0001 Link-level <--> hardware-level communication
0x0002 Top state machine
0x0004 D-Channel Frames for isdnlog
0x0008 D-Channel Q.921
0x0010 B-Channel X.75
0x0020 D-Channel l2
0x0040 B-Channel l2
0x0080 D-Channel link state debugging
0x0100 B-Channel link state debugging
0x0200 TEI debug
0x0400 LOCK debug in callc.c
0x0800 More paranoid debug in callc.c (not for normal use)
0x1000 D-Channel l1 state debugging
0x2000 B-Channel l1 state debugging
With DebugCmd set to 11:
0x0001 Warnings (default: on)
0x0002 IRQ status
0x0004 ISAC
0x0008 ISAC FIFO
0x0010 HSCX
0x0020 HSCX FIFO (attention: full B-Channel output!)
0x0040 D-Channel LAPD frame types
0x0080 IPAC debug
0x0100 HFC receive debug
0x0200 ISAC monitor debug
0x0400 D-Channel frames for isdnlog (set with 1 0x4 too)
0x0800 D-Channel message verbose
With DebugCmd set to 13:
1 Warnings (default: on)
2 l3 protocol descriptor errors
4 l3 state machine
8 charge info debugging (1TR6)
For example, 'hisaxctrl HiSax 1 0x3ff' enables full generic debugging.
Because of some obscure problems with some switch equipment, the delay
between the CONNECT message and sending the first data on the B-channel is now
configurable with
hisaxctrl <DriverId> 2 <delay>
<delay> in ms Value between 50 and 800 ms is recommended.
Downloading Firmware
--------------------
At the moment, the Sedlbauer speed fax+ is the only card, which
needs to download firmware.
The firmware is downloaded with the hisaxctrl tool:
hisaxctrl <DriverId> 9 <firmware_filename>
<DriverId> default is HiSax, if you didn't specify one,
where <firmware_filename> is the filename of the firmware file.
For example, 'hisaxctrl HiSax 9 ISAR.BIN' downloads the firmware for
ISAR based cards (like the Sedlbauer speed fax+).
Warning
-------
HiSax is a work in progress and may crash your machine.
For certification look at HiSax.cert file.
Limitations
-----------
At this time, HiSax only works on Euro ISDN lines and German 1TR6 lines.
For leased lines see appendix.
Bugs
----
If you find any, please let me know.

for instructions.
Appendix: Linux and ISDN-leased lines
-------------------------------------
Original from Juergen Quade, new version KKe.
Attention NEW VERSION, the old leased line syntax won't work !!!
You can use HiSax to connect your Linux-Box via an ISDN leased line
to e.g. the Internet:
1. Build a kernel which includes the HiSax driver either as a module
or as part of the kernel.
cd /usr/src/linux
make menuconfig
<ISDN subsystem - ISDN support -- HiSax>
make clean; make dep; make zImage; make modules; make modules_install
2. Install the new kernel
cp /usr/src/linux/arch/i386/boot/zImage /etc/kernel/linux.isdn
vi /etc/lilo.conf
<add new kernel in the bootable image section>
lilo
3. in case the hisax driver is a "fixed" part of the kernel, configure
the driver with lilo:
vi /etc/lilo.conf
<add HiSax driver parameter in the global section (see below)>
lilo
Your lilo.conf _might_ look like the following:
# LILO configuration-file
# global section
# teles 16.0 on IRQ=5, MEM=0xd8000, PORT=0xd80
append="hisax=1,3,5,0xd8000,0xd80,HiSax"
# teles 16.3 (non pnp) on IRQ=15, PORT=0xd80
# append="hisax=3,3,5,0xd8000,0xd80,HiSax"
boot=/dev/sda
compact # faster, but won't work on all systems.
linear
read-only
prompt
timeout=100
vga = normal # force sane state
# Linux bootable partition config begins
image = /etc/kernel/linux.isdn
root = /dev/sda1
label = linux.isdn
#
image = /etc/kernel/linux-2.0.30
root = /dev/sda1
label = linux.secure
In the line starting with "append" you have to adapt the parameters
according to your card (see above in this file)
3. boot the new linux.isdn kernel
4. start the ISDN subsystem:
a) load - if necessary - the modules (depends, whether you compiled
the ISDN driver as module or not)
According to the type of card you have to specify the necessary
driver parameter (irq, io, mem, type, protocol).
For the leased line the protocol is "3". See the table above for
the parameters, which you have to specify depending on your card.
b) configure i4l
/sbin/isdnctrl addif isdn0
# EAZ 1 -- B1 channel 2 --B2 channel
/sbin/isdnctrl eaz isdn0 1
/sbin/isdnctrl secure isdn0 on
/sbin/isdnctrl huptimeout isdn0 0
/sbin/isdnctrl l2_prot isdn0 hdlc
# Attention you must not set an outgoing number !!! This won't work !!!
# The incomming number is LEASED0 for the first card, LEASED1 for the
# second and so on.
/sbin/isdnctrl addphone isdn0 in LEASED0
# Here is no need to bind the channel.
c) in case the remote partner is a CISCO:
/sbin/isdnctrl encap isdn0 cisco-h
d) configure the interface
/sbin/ifconfig isdn0 ${LOCAL_IP} pointopoint ${REMOTE_IP}
e) set the routes
/sbin/route add -host ${REMOTE_IP} isdn0
/sbin/route add default gw ${REMOTE_IP}
f) switch the card into leased mode for each used B-channel
/sbin/hisaxctrl HiSax 5 1
Remarks:
a) Use state of the art isdn4k-utils
Here an example script:
#!/bin/sh

This document describes the ACT2000 driver for the
IBM Active 2000 ISDN card.
There are 3 Types of this card available. A ISA-, MCA-, and PCMCIA-Bus
Version. Currently, only the ISA-Bus version of the card is supported.
However MCA and PCMCIA will follow soon.
The ISA-Bus Version uses 8 IO-ports. The base port adress has to be set
manually using the DIP switches.
Setting up the DIP switches for the IBM Active 2000 ISDN card:
Note: S5 and S6 always set off!
S1 S2 S3 S4 Base-port
on on on on 0x0200 (Factory default)

IRQ is configured by software. Possible values are:
3, 5, 7, 10, 11, 12, 15 and none (polled mode)
The ACT2000 driver may either be built into the kernel or as a module.
Initialization depends on how the driver is built:
Driver built into the kernel:
The ACT2000 driver can be configured using the commandline-feature while
loading the kernel with LILO or LOADLIN. It accepts the following syntax:
act2000=b,p,i[,idstring]
where
b = Bus-Type (1=ISA, 2=MCA, 3=PCMCIA)
p = portbase (-1 means autoprobe)
i = Interrupt (-1 means use next free IRQ, 0 means polled mode)
The idstring is an arbitrary string used for referencing the card
by the actctrl tool later.
Defaults used, when no parameters given at all:
1,-1,-1,""
which means: Autoprobe for an ISA card, use next free IRQ, let the
ISDN linklevel fill the IdString (usually "line0" for the first card).
If you like to use more than one card, you can use the program
"actctrl" from the utility-package to configure additional cards.
Using the "actctrl"-utility, portbase and irq can also be changed
during runtime. The D-channel protocol is configured by the "dproto"
option of the "actctrl"-utility after loading the firmware into the
card's memory using the "actctrl"-utility.
Driver built as module:
The module act2000.o can be configured during modprobe (insmod) by
appending its parameters to the modprobe resp. insmod commandline.
The following syntax is accepted:
act_bus=b act_port=p act_irq=i act_id=idstring
where b, p, i and idstring have the same meanings as the parameters
described for the builtin version above.
Using the "actctrl"-utility, the same features apply to the modularized
version as to the kernel-builtin one. (i.e. loading of firmware and
configuring the D-channel protocol)
Loading the firmware into the card:
The firmware is supplied together with the isdn4k-utils package. It
can be found in the subdirectory act2000/firmware/
Assuming you have installed the utility-package correctly, the firmware
will be downloaded into the card using the following command:
actctrl -d idstring load /etc/isdn/bip11.btl
where idstring is the Name of the card, given during insmod-time or
(for kernel-builtin driver) on the kernel commandline. If only one
ISDN card is used, the -d isdstrin may be omitted.
For further documentation (adding more IBM Active 2000 cards), refer to
the manpage actctrl.8 which is included in the isdn4k-utils package.

ISDN subsystem for Linux.
Description of audio mode.
When enabled during kernel configuration, the tty emulator of the ISDN
subsystem is capable of a reduced set of commands to support audio.
This document describes the commands supported and the format of
audio data.
Commands for enabling/disabling audio mode:
AT+FCLASS=8 Enable audio mode.
This affects the following registers:
S18: Bits 0 and 2 are set.
S16: Set to 48 and any further change to
larger values is blocked.
AT+FCLASS=0 Disable audio mode.
Register 18 is set to 4.
AT+FCLASS=? Show possible modes.
AT+FCLASS? Report current mode (0 or 8).
Commands supported in audio mode:
All audio mode commands have one of the following forms:
AT+Vxx? Show current setting.
AT+Vxx=? Show possible settings.
AT+Vxx=v Set simple parameter.
AT+Vxx=v,v ... Set complex parameter.
where xx is a two-character code and v are alphanumerical parameters.
The following commands are supported:
AT+VNH=x Auto hangup setting. NO EFFECT, supported
for compatibility only.
AT+VNH? Always reporting "1"
AT+VNH=? Always reporting "1"
AT+VIP Reset all audio parameters.
AT+VLS=x Line select. x is one of the following:
0 = No device.
2 = Phone line.
AT+VLS=? Always reporting "0,2"
AT+VLS? Show current line.
AT+VRX Start recording. Emulator responds with
CONNECT and starts sending audio data to
the application. See below for data format
AT+VSD=x,y Set silence-detection parameters.
Possible parameters:
x = 0 ... 31 sensitivity threshold level.
(default 0 , deactivated)
y = 0 ... 255 range of interval in units
of 0.1 second. (default 70)
AT+VSD=? Report possible parameters.
AT+VSD? Show current parameters.
AT+VDD=x,y Set DTMF-detection parameters.
Only possible if online and during this connection.
Possible parameters:
x = 0 ... 15 sensitivity threshold level.
(default 0 , I4L soft-decode)
(1-15 soft-decode off, hardware on)
y = 0 ... 255 tone duration in units of 5ms.
Not for I4L soft decode (default 8, 40ms)
AT+VDD=? Report possible parameters.
AT+VDD? Show current parameters.
AT+VSM=x Select audio data format.
Possible parameters:
2 = ADPCM-2
3 = ADPCM-3
4 = ADPCM-4
5 = aLAW
6 = uLAW
AT+VSM=? Show possible audio formats.
AT+VTX Start audio playback. Emulator responds
with CONNECT and starts sending audio data
received from the application via phone line.
General behavior and description of data formats/protocol.
when a connection is made:
On incoming calls, if the application responds to a RING
with ATA, depending on the calling service, the emulator
responds with either CONNECT (data call) or VCON (voice call).
On outgoing voice calls, the emulator responds with VCON
upon connection setup.
Audio recording.
When receiving audio data, a kind of bisync protocol is used.
Upon AT+VRX command, the emulator responds with CONNECT, and
starts sending audio data to the application. There are several
escape sequences defined, all using DLE (0x10) as Escape char:
<DLE><ETX> End of audio data. (i.e. caused by a
hangup of the remote side) Emulator stops
recording, responding with VCON.
<DLE><DC4> Abort recording, (send by appl.) Emulator
stops recording, sends DLE,ETX.
<DLE><DLE> Escape sequence for DLE in data stream.
<DLE>0 Touchtone "0" received.
...
<DLE>9 Touchtone "9" received.
<DLE># Touchtone "#" received.
<DLE>* Touchtone "*" received.
<DLE>A Touchtone "A" received.
<DLE>B Touchtone "B" received.
<DLE>C Touchtone "C" received.
<DLE>D Touchtone "D" received.
<DLE>q quiet. Silence detected after non-silence.
<DLE>s silence. Silence detected from the
start of recording.
Currently unsupported DLE sequences:
<DLE>c FAX calling tone received.
<DLE>b busy tone received.
Audio playback.
When sending audio data, upon AT+VTX command, emulator responds with
CONNECT, and starts transferring data from application to the phone line.
The same DLE sequences apply to this mode.
Full-Duplex-Audio:
When _both_ commands for recording and playback are given in _one_
AT-command-line (i.e.: "AT+VTX+VRX"), full-duplex-mode is selected.
In this mode, the only way to stop recording is sending <DLE><DC4>
and the only way to stop playback is to send <DLE><ETX>.

Description of the "concap" encapsulation protocol interface
============================================================
The "concap" interface is intended to be used by network device
drivers that need to process an encapsulation protocol.
It is assumed that the protocol interacts with a linux network device by
- data transmission
- connection control (establish, release)
Thus, the mnemonic: "CONnection CONtrolling eNCAPsulation Protocol".
This is currently only used inside the isdn subsystem. But it might
also be useful to other kinds of network devices. Thus, if you want
to suggest changes that improve usability or performance of the
interface, please let me know. I'm willing to include them in future
releases (even if I needed to adapt the current isdn code to the
changed interface).
Why is this useful?
===================
The encapsulation protocol used on top of WAN connections or permanent
point-to-point links are frequently chosen upon bilateral agreement.
Thus, a device driver for a certain type of hardware must support
several different encapsulation protocols at once.
The isdn device driver did already support several different
encapsulation protocols. The encapsulation protocol is configured by a
user space utility (isdnctrl). The isdn network interface code then
uses several case statements which select appropriate actions
depending on the currently configured encapsulation protocol.
In contrast, LAN network interfaces always used a single encapsulation
protocol which is unique to the hardware type of the interface. The LAN
encapsulation is usually done by just sticking a header on the data. Thus,
traditional linux network device drivers used to process the
encapsulation protocol directly (usually by just providing a hard_header()
method in the device structure) using some hardware type specific support
functions. This is simple, direct and efficient. But it doesn't fit all
the requirements for complex WAN encapsulations.
The configurability of the encapsulation protocol to be used
makes isdn network interfaces more flexible, but also much more
complex than traditional lan network interfaces.
Many Encapsulation protocols used on top of WAN connections will not just
stick a header on the data. They also might need to set up or release
the WAN connection. They also might want to send other data for their
private purpose over the wire, e.g. ppp does a lot of link level
negotiation before the first piece of user data can be transmitted.
Such encapsulation protocols for WAN devices are typically more complex
than encapsulation protocols for lan devices. Thus, network interface
code for typical WAN devices also tends to be more complex.
In order to support Linux' x25 PLP implementation on top of
isdn network interfaces I could have introduced yet another branch to
the various case statements inside drivers/isdn/isdn_net.c.
This eventually made isdn_net.c even more complex. In addition, it made
isdn_net.c harder to maintain. Thus, by identifying an abstract
interface between the network interface code and the encapsulation
protocol, complexity could be reduced and maintainability could be
increased.
Likewise, a similar encapsulation protocol will frequently be needed by
several different interfaces of even different hardware type, e.g. the
synchronous ppp implementation used by the isdn driver and the
asyncronous ppp implementation used by the ppp driver have a lot of
similar code in them. By cleanly separating the encapsulation protocol
from the hardware specific interface stuff such code could be shared
better in future.
When operating over dial-up-connections (e.g. telephone lines via modem,
non-permanent virtual circuits of wide area networks, ISDN) many
encapsulation protocols will need to control the connection. Therefore,
some basic connection control primitives are supported. The type and
semantics of the connection (i.e the ISO layer where connection service
is provided) is outside our scope and might be different depending on
the encapsulation protocol used, e.g. for a ppp module using our service
on top of a modem connection a connect_request will result in dialing
a (somewhere else configured) remote phone number. For an X25-interface
module (LAPB semantics, as defined in Documentation/networking/x25-iface.txt)
a connect_request will ask for establishing a reliable lapb
datalink connection.
The encapsulation protocol currently provides the following
service primitives to the network device.
- create a new encapsulation protocol instance
- delete encapsulation protocol instance and free all its resources
- initialize (open) the encapsulation protocol instance for use.
- deactivate (close) an encapsulation protocol instance.
- process (xmit) data handed down by upper protocol layer
- receive data from lower (hardware) layer
- process connect indication from lower (hardware) layer
- process disconnect indication from lower (hardware) layer
The network interface driver accesses those primitives via callbacks
provided by the encapsulation protocol instance within a
struct concap_proto_ops.
struct concap_proto_ops{
/* create a new encapsulation protocol instance of same type */
struct concap_proto * (*proto_new) (void);
/* delete encapsulation protocol instance and free all its resources.
cprot may no loger be referenced after calling this */
void (*proto_del)(struct concap_proto *cprot);
/* initialize the protocol's data. To be called at interface startup
or when the device driver resets the interface. All services of the
encapsulation protocol may be used after this*/
int (*restart)(struct concap_proto *cprot,
struct net_device *ndev,
struct concap_device_ops *dops);
/* deactivate an encapsulation protocol instance. The encapsulation
protocol may not call any *dops methods after this. */
int (*close)(struct concap_proto *cprot);
/* process a frame handed down to us by upper layer */
int (*encap_and_xmit)(struct concap_proto *cprot, struct sk_buff *skb);
/* to be called for each data entity received from lower layer*/
int (*data_ind)(struct concap_proto *cprot, struct sk_buff *skb);
/* to be called when a connection was set up/down.
Protocols that don't process these primitives might fill in
dummy methods here */
int (*connect_ind)(struct concap_proto *cprot);
int (*disconn_ind)(struct concap_proto *cprot);
};
The data structures are defined in the header file include/linux/concap.h.
A Network interface using encapsulation protocols must also provide
some service primitives to the encapsulation protocol:
- request data being submitted by lower layer (device hardware)
- request a connection being set up by lower layer
- request a connection being released by lower layer
The encapsulation protocol accesses those primitives via callbacks
provided by the network interface within a struct concap_device_ops.
struct concap_device_ops{
/* to request data be submitted by device */
int (*data_req)(struct concap_proto *, struct sk_buff *);
/* Control methods must be set to NULL by devices which do not
support connection control. */
/* to request a connection be set up */
int (*connect_req)(struct concap_proto *);
/* to request a connection be released */
int (*disconn_req)(struct concap_proto *);
};
The network interface does not explicitly provide a receive service
because the encapsulation protocol directly calls netif_rx().
An encapsulation protocol itself is actually the
struct concap_proto{
struct net_device *net_dev; /* net device using our service */
struct concap_device_ops *dops; /* callbacks provided by device */
struct concap_proto_ops *pops; /* callbacks provided by us */
int flags;
void *proto_data; /* protocol specific private data, to
be accessed via *pops methods only*/
/*
:
whatever
:
*/
};
Most of this is filled in when the device requests the protocol to
be reset (opend). The network interface must provide the net_dev and
dops pointers. Other concap_proto members should be considered private
data that are only accessed by the pops callback functions. Likewise,
a concap proto should access the network device's private data
only by means of the callbacks referred to by the dops pointer.
A possible extended device structure which uses the connection controlling
encapsulation services could look like this:
struct concap_device{
struct net_device net_dev;
struct my_priv /* device->local stuff */
/* the my_priv struct might contain a
struct concap_device_ops *dops;
to provide the device specific callbacks
*/
struct concap_proto *cprot; /* callbacks provided by protocol */
};
Misc Thoughts
=============
The concept of the concap proto might help to reuse protocol code and
reduce the complexity of certain network interface implementations.
The trade off is that it introduces yet another procedure call layer
when processing the protocol. This has of course some impact on
performance. However, typically the concap interface will be used by
devices attached to slow lines (like telephone, isdn, leased synchronous
lines). For such slow lines, the overhead is probably negligible.
This might no longer hold for certain high speed WAN links (like
ATM).
If general linux network interfaces explicitly supported concap
protocols (e.g. by a member struct concap_proto* in struct net_device)
then the interface of the service function could be changed
by passing a pointer of type (struct net_device*) instead of
type (struct concap_proto*). Doing so would make many of the service
functions compatible to network device support functions.
e.g. instead of the concap protocol's service function
int (*encap_and_xmit)(struct concap_proto *cprot, struct sk_buff *skb);
we could have
int (*encap_and_xmit)(struct net_device *ndev, struct sk_buff *skb);
As this is compatible to the dev->hard_start_xmit() method, the device
driver could directly register the concap protocol's encap_and_xmit()
function as its hard_start_xmit() method. This would eliminate one
procedure call layer.
The device's data request function could also be defined as
int (*data_req)(struct net_device *ndev, struct sk_buff *skb);
This might even allow for some protocol stacking. And the network
interface might even register the same data_req() function directly
as its hard_start_xmit() method when a zero layer encapsulation
protocol is configured. Thus, eliminating the performance penalty
of the concap interface when a trivial concap protocol is used.
Nevertheless, the device remains able to support encapsulation
protocol configuration.

1. Features of the i4l diversion services
(Or what can the i4l diversion services do for me)
The i4l diversion services offers call forwarding and logging normally
only supported by isdn phones. Incoming calls may be diverted
unconditionally (CFU), when not reachable (CFNR) or on busy condition
(CFB).
The diversions may be invoked statically in the providers exchange
as normally done by isdn phones. In this case all incoming calls
with a special (or all) service identifiers are forwarded if the
forwarding reason is met. Activated static services may also be
interrogated (queried).
The i4l diversion services additionally offers a dynamic version of
call forwarding which is not preprogrammed inside the providers exchange
but dynamically activated by i4l.
In this case all incoming calls are checked by rules that may be
compared to the mechanism of ipfwadm or ipchains. If a given rule matches
the checking process is finished and the rule matching will be applied
to the call.
The rules include primary and secondary service indentifiers, called
number and subaddress, callers number and subaddress and whether the rule
matches to all filtered calls or only those when all B-channel resources
are exhausted.
Actions that may be invoked by a rule are ignore, proceed, reject,
direct divert or delayed divert of a call.
All incoming calls matching a rule except the ignore rule a reported and
logged as ASCII via the proc filesystem (/proc/net/isdn/divert). If proceed
is selected the call will be held in a proceeding state (without ringing)
for a certain amount of time to let an external program or client decide
how to handle the call.
2. Required hard- and software
For using the i4l diversion services the isdn line must be of a EURO/DSS1
type. Additionally the i4l services only work together with the HiSax
driver for passive isdn cards. All HiSax supported cards may be used for
the diversion purposes.
The static diversion services require the provider having static services
CFU, CFNR, CFB activated on an MSN-line. The static services may not be
used on a point-to-point connection. Further the static services are only
available in some countries (for example germany). Countries requiring the
keypad protocol for activating static diversions (like the netherlands) are
not supported but may use the tty devices for this purpose.
The dynamic diversion servives may be used in all countries if the provider
enables the feature CF (call forwarding). This should work on both MSN- and
point-to-point lines.
To add and delete rules the additional divertctrl program is needed. This
program is part of the isdn4kutils package.
3. Compiling, installing and loading/unloading the module
Tracing calling and diversion information
To compile the i4l code with diversion support you need to say yes to the
DSS1 diversion services when selecting the i4l options in the kernel
config (menuconfig or config).
After having properly activated a make modules and make modules_install all
required modules will be correctly installed in the needed modules dirs.
As the diversion services are currently not included in the scripts of most
standard distributions you will have to add a "insmod dss1_divert" after
having loaded the global isdn module.
The module can be loaded without any command line parameters.
If the module is actually loaded and active may be checked with a
"cat /proc/modules" or "ls /proc/net/isdn/divert". The divert file is
dynamically created by the diversion module and removed when the module is
unloaded.
4. Tracing calling and diversion information
You also may put a "cat /proc/net/isdn/divert" in the background with the
output redirected to a file. Then all actions of the module are logged.
The divert file in the proc system may be opened more than once, so in
conjunction with inetd and a small remote client on other machines inside
your network incoming calls and reactions by the module may be shown on
every listening machine.
If a call is reported as proceeding an external program or client may
specify during a certain amount of time (normally 4 to 10 seconds) what
to do with that call.
To unload the module all open files to the device in the proc system must
be closed. Otherwise the module (and isdn.o) may not be unloaded.
5. Format of the divert device ASCII output
To be done later

- S2M-Card ISA
DIVA Server family
------------------
- DIVA Server BRI/PCI 2M
- DIVA Server PRI/PCI 2M (9M 23M 30M)
supported functions of onboard DSPs:
- analog modem
- fax group 2/3 (Fax Class 2 commands)
- DTMF detection
ISDN D-Channel Protocols
------------------------
- ETSI (Euro-DSS1)
- 1TR6 (German ISDN) *not testet*
- other protocols exist for the range of DIVA Server cards,
but they are not fully testet yet.
You can load the module simply by using the insmod or modprobe function :
insmod eicon [id=driverid] [membase=<membase>] [irq=<irq>]
The module will automatically probe the PCI-cards. If the id-option
is omitted, the driver will assume 'eicon0' for the first pci card and
increases the digit with each further card. With a given driver-id
the module appends a number starting with '0'.
For ISA-cards you have to specify membase, irq and id. If id or
membase is missing/invalid, the driver will not be loaded except
PCI-cards were found. Additional ISA-cards and irq/membase changes
can be done with the eiconctrl utility.
After loading the module, you have to download the protocol and
dsp-code by using the eiconctrl utility of isdn4k-utils.
Example for loading and starting a BRI card with E-DSS1 Protocol.
eiconctrl [-d DriverId] load etsi
Example for loading and starting a PRI card with E-DSS1 Protocol.
eiconctrl [-d DriverId] load etsi -s2 -n
Details about using the eiconctrl utility are in 'man eiconctrl'
or will be printed by starting eiconctrl without any parameters.
ISDNLOG:
With eicon driver version 1.77 or newer and the eiconctrl utility
of version 1.1 or better, you can use the isdnlog user program
with your DIVA Server BRI card.
Just use "eiconctrl isdnlog on" and the driver will generate
the necessary D-Channel traces for isdnlog.

Fax with isdn4linux
===================
When enabled during kernel configuration, the tty emulator
of the ISDN subsystem is capable of the Fax Class 2 commands.
This only makes sense under the following conditions :
- You need the commands as dummy, because you are using
hylafax (with patch) for AVM capi.
- You want to use the fax capabilities of your isdn-card.
(supported cards are listed below)
NOTE: This implementation does *not* support fax with passive
ISDN-cards (known as softfax). The low-level driver of
the ISDN-card and/or the card itself must support this.
Supported ISDN-Cards
--------------------
Eicon DIVA Server BRI/PCI
- full support with both B-channels.
Eicon DIVA Server PRI/PCI
- full support on amount of B-channels
depending on DSPs on board.
The command set is known as Class 2 (not Class 2.0) and
can be activated by AT+FCLASS=2
The interface between the link-level-module and the hardware-level driver
is described in the files INTERFACE.fax and INTERFACE.

The driver for the HFC-PCI and HFC-PCI-A chips from CCD may be used
for many OEM cards using this chips.
Additionally the driver has a special feature which makes it possible
to read the echo-channel of the isdn bus. So all frames in both directions
may be logged.
When the echo logging feature is used the number of available B-channels
for a HFC-PCI card is reduced to 1. Of course this is only relevant to
the card, not to the isdn line.
To activate the echo mode the following ioctls must be entered:
hisaxctrl <driver/cardname> 10 1
This reduces the available channels to 1. There must not be open connections
through this card when entering the command.
And then:
hisaxctrl <driver/cardname> 12 1
This enables the echo mode. If Hex logging is activated the isdnctrlx
devices show a output with a line beginning of HEX: for the providers
exchange and ECHO: for isdn devices sending to the provider.
If more than one HFC-PCI cards are installed, a specific card may be selected
at the hisax module load command line. Supply the load command with the desired
IO-address of the desired card.
Example:
There tree cards installed in your machine at IO-base addresses 0xd000, 0xd400
and 0xdc00
If you want to use the card at 0xd400 standalone you should supply the insmod
or depmod with type=35 io=0xd400.
If you want to use all three cards, but the order needs to be at 0xdc00,0xd400,
0xd000 you may give the parameters type=35,35,35 io=0xdc00,0xd400,0xd00
Then the desired card will be the initialised in the desired order.
If the io parameter is used the io addresses of all used cards should be
supplied else the parameter is assumed 0 and a auto search for a free card is
invoked which may not give the wanted result.

1. About the driver
2. Loading/Unloading the driver
3. Entries in the /proc filesystem
4. The /proc/net/hysdn/cardconfX file
5. The /proc/net/hysdn/cardlogX file
6. Where to get additional info and help
1. About the driver
The drivers/isdn/hysdn subdir contains a driver for HYPERCOPEs active
PCI isdn cards Champ, Ergo and Metro. To enable support for this cards
enable ISDN support in the kernel config and support for HYSDN cards in
the active cards submenu. The driver may only be compiled and used if
support for loadable modules and the process filesystem have been enabled.
No other ISDN options need to be enabled for these cards.
Up to now these cards do not use or require the standard isdn interface
module (isdn.o), but registers itself as an ethernet card. All necessary
handlers for various protocols like ppp and others as well as config info
and firmware may be fetched from Hypercopes WWW-Site www.hypercope.de.
The driver has been included in the i4l tree as a CAPI compliant module
is under development and will be connected to the standard i4l modules
additionally.
2. Loading/Unloading the driver
The module has no command line parameters and auto detects up to 10 cards
in the id-range 0-9.
If a loaded driver shall be unloaded all open files in the /proc/net/hysdn
subdir need to be closed and all ethernet interfaces allocated by this
driver must be shut down. Otherwise the module counter will avoid a module
unload.
3. Entries in the /proc filesystem
When the module has been loaded it adds the directory hysdn in the
/proc/net tree. This directory contains exactly 2 file entries for each
card. One is called cardconfX and the other cardlogX, where X is the
card id number from 0 to 9.
The cards are numbered in the order found in the PCI config data.
4. The /proc/net/hysdn/cardconfX file
This file may be read to get by everyone to get info about the cards type,
actual state, available features and used resources.
The first 3 entries (id, bus and slot) are PCI info fields, the following
type field gives the information about the cards type:
4 -> Ergo card (server card with 2 b-chans)
5 -> Metro card (server card with 4 or 8 b-chans)
6 -> Champ card (client card with 2 b-chans)
The following 3 fields show the hardware assignments for irq, iobase and the
dual ported memory (dp-mem).
The fields b-chans and fax-chans announce the available card resources of
this types for the user.
The state variable indicates the actual drivers state for this card with the
following assignments.
0 -> card has not been booted since driver load
1 -> card booting is actually in progess
2 -> card is in an error state due to a previous boot failure
3 -> card is booted and active
And the last field (device) shows the name of the ethernet device assigned
to this card. Up to the first successfull boot this field only shows a -
to tell that no net device has been allocated up to now. Once a net device
has been allocated it remains assigned to this card, even if a card is
rebooted and an boot error occurs.
Writing to the cardconfX file boots the card or transfers config lines to
the cards firmware. The type of data is automatically detected when the
first data is written. Only root has write access to this file.
The firmware boot files are normally called hyclient.pof for client cards
and hyserver.pof for server cards.
After successfully writing the boot file, complete config files or single
config lines may be copied to this file.
If an error occurs the return value given to the writing process has the
following additional codes (decimal):
1000 Another process is currently bootng the card
1001 Invalid firmware header
1002 Boards dual-port RAM test failed
1003 Internal firmware handler error
1004 Boot image size invalid
1005 First boot stage (bootstrap loader) failed
1006 Second boot stage failure
1007 Timeout waiting for card ready during boot
1008 Operation only allowed in booted state
1009 Config line to long
1010 Invalid channel number
1011 Timeout sending config data
Additional info about error reasons may be fetched from the log output.
5. The /proc/net/hysdn/cardlogX file
The cardlogX file entry may be opened multiple for reading by everyone to
get the cards and drivers log data. Card messages always start with the
keyword LOG. All other lines are output from the driver.
The driver log data may be redirected to the syslog by selecting the
approriate bitmask. The cards log messages will always be send to this
interface but never to the syslog.
A root user may write a decimal or hex (with 0x) value t this file to select
desired output options. As mentioned above the cards log dat is always
written to the cardlog file independant of the following options only used
to check and debug the driver itself:
For example:
echo "0x34560078" > /proc/net/hysdn/cardlog0
to output the hex log mask 34560078 for card 0.
The written value is regarded as an unsigned 32-Bit value, bit ored for
desired output. The following bits are already assigned:
0x80000000 All driver log data is alternatively via syslog
0x00000001 Log memory allocation errors
0x00000010 Firmware load start and close are logged
0x00000020 Log firmware record parser
0x00000040 Log every firmware write actions
0x00000080 Log all card related boot messages
0x00000100 Output all config data sent for debugging purposes
0x00000200 Only non comment config lines are shown wth channel
0x00000400 Additional conf log output
0x00001000 Log the asynchronous scheduler actions (config and log)
0x00100000 Log all open and close actions to /proc/net/hysdn/card files
0x00200000 Log all actions from /proc file entries
0x00010000 Log network interface init and deinit

The card communicates with the PC by two interfaces:
1. A range of 4 successive port-addresses, whose base address can be
configured with the switches.
2. A memory window with 16KB-256KB size, which can be setup in 16k steps
over the whole range of 16MB. Isdn4linux only uses a 16k window.
The base address of the window can be configured when loading
the lowlevel-module (see README). If using more than one card,
all cards are mapped to the same window and activated as needed.
Setting up the IO-address dipswitches for the ICN-ISDN-card:

The ICN driver may be built into the kernel or as a module. Initialization
depends on how the driver is built:
Driver built into the kernel:
The ICN driver can be configured using the commandline-feature while
loading the kernel with LILO or LOADLIN. It accepts the following syntax:
icn=p,m[,idstring1[,idstring2]]
where
p = portbase (default: 0x320)
m = shared memory (default: 0xd0000)
When using the ICN double card (4B), you MUST define TWO idstrings.
idstring must start with a character! There is no way for the driver
to distinguish between a 2B and 4B type card. Therefore, by supplying
TWO idstrings, you tell the driver that you have a 4B installed.
If you like to use more than one card, you can use the program
"icnctrl" from the utility-package to configure additional cards.
You need to configure shared memory only once, since the icn-driver
maps all cards into the same address-space.
Using the "icnctrl"-utility, portbase and shared memory can also be
changed during runtime.
The D-channel protocol is configured by loading different firmware
into the card's memory using the "icnctrl"-utility.
Driver built as module:
The module icn.o can be configured during "insmod'ing" it by
appending its parameters to the insmod-commandline. The following
syntax is accepted:
portbase=p membase=m icn_id=idstring [icn_id2=idstring2]
where p, m, idstring1 and idstring2 have the same meanings as the
parameters described for the kernel-version above.
When using the ICN double card (4B), you MUST define TWO idstrings.
idstring must start with a character! There is no way for the driver
to distinguish between a 2B and 4B type card. Therefore, by supplying
TWO idstrings, you tell the driver that you have a 4B installed.
Using the "icnctrl"-utility, the same features apply to the modularized
version like to the kernel-builtin one.
The D-channel protocol is configured by loading different firmware
into the card's memory using the "icnctrl"-utility.
Loading the firmware into the card:
The firmware is supplied together with the isdn4k-utils package. It
can be found in the subdirectory icnctrl/firmware/
There are 3 files:
loadpg.bin - Image of the bootstrap loader.
pc_1t_ca.bin - Image of firmware for german 1TR6 protocol.
pc_eu_ca.bin - Image if firmware for EDSS1 (Euro-ISDN) protocol.
Assuming you have installed the utility-package correctly, the firmware
will be downloaded into the 2B-card using the following command:
icnctrl -d Idstring load /etc/isdn/loadpg.bin /etc/isdn/pc_XX_ca.bin
where XX is either "1t" or "eu", depending on the D-Channel protocol
used on your S0-bus and Idstring is the Name of the card, given during
insmod-time or (for kernel-builtin driver) on the kernel commandline.
To load a 4B-card, the same command is used, except a second firmware
file is appended to the commandline of icnctrl.
-> After dowloading firmware, the two LEDs at the back cover of the card
(ICN-4B: 4 LEDs) must be blinking intermittently now. If a connection
is up, the corresponding led is lit continuously.
For further documentation (adding more ICN-cards), refer to the manpage
icnctrl.8 which is included in the isdn4k-utils package.

README file for the PCBIT-D Device Driver.
------------------------------------------------------------------------------
The PCBIT is a Euro ISDN adapter manufactured in Portugal by Octal and
developed in cooperation with Portugal Telecom and Inesc.
The driver interfaces with the standard kernel isdn facilities
originally developed by Fritz Elfert in the isdn4linux project.
The common versions of the pcbit board require a firmware that is
distributed (and copyrighted) by the manufacturer. To load this
firmware you need "pcbitctl" available on the standard isdn4k-utils
package or in the pcbit package available in:
ftp://ftp.di.fc.ul.pt/pub/systems/Linux/isdn
Known Limitations:
- The board reset procedure is at the moment incorrect and will only
allow you to load the firmware after a hard reset.
- Only HDLC in B-channels is supported at the moment. There is no
current support for X.25 in B or D channels nor LAPD in B
channels. The main reason is that these two other protocol modes have,
to my knowledge, very little use. If you want to see them implemented
*do* send me a mail.
- The driver often triggers errors in the board that I and the
manufacturer believe to be caused by bugs in the firmware. The current
version includes several procedures for error recovery that should
allow normal operation. Plans for the future include cooperation with
the manufacturer in order to solve this problem.
Information/hints/help can be obtained in the linux isdn
mailing list (isdn4linux@listserv.isdn4linux.de) or directly from me.

Pedro.

Some additional information for setting up a syncPPP
connection using network interfaces.
---------------------------------------------------------------
You need one thing beside the isdn4linux package:
a patched pppd .. (I called it ipppd to show the difference)
Compiling isdn4linux with sync PPP:
-----------------------------------
To compile isdn4linux with the sync PPP part, you have
to answer the appropriate question when doing a "make config"
Don't forget to load the slhc.o
module before the isdn.o module, if VJ-compression support
is not compiled into your kernel. (e.g if you have no PPP or
CSLIP in the kernel)
Using isdn4linux with sync PPP:
-------------------------------
Sync PPP is just another encapsulation for isdn4linux. The
name to enable sync PPP encapsulation is 'syncppp' .. e.g:
/sbin/isdnctrl encap ippp0 syncppp
The name of the interface is here 'ippp0'. You need
one interface with the name 'ippp0' to saturate the
ipppd, which checks the ppp version via this interface.
Currently, all devices must have the name ipppX where
'X' is a decimal value.
To set up a PPP connection you need the ipppd .. You must start
the ipppd once after installing the modules. The ipppd
communicates with the isdn4linux link-level driver using the
/dev/ippp0 to /dev/ippp15 devices. One ipppd can handle
all devices at once. If you want to use two PPP connections
at the same time, you have to connect the ipppd to two
devices .. and so on.
I've implemented one additional option for the ipppd:
'useifip' will get (if set to not 0.0.0.0) the IP address
for the negotiation from the attached network-interface.
(also: ipppd will try to negotiate pointopoint IP as remote IP)
You must disable BSD-compression, this implementation can't
handle compressed packets.
Check the etc/rc.isdn.syncppp in the isdn4kernel-util package
for an example setup script.
To use the MPPP stuff, you must configure a slave device
with isdn4linux. Now call the ipppd with the '+mp' option.
To increase the number of links, you must use the
'addlink' option of the isdnctrl tool. (rc.isdn.syncppp.MPPP is
an example script)
enjoy it,
michael

X.25 support within isdn4linux
==============================
This is alpha/beta test code. Use it completely at your own risk.
As new versions appear, the stuff described here might suddenly change
or become invalid without notice.
Keep in mind:
You are using several new parts of the 2.2.x kernel series which
have not been tested in a large scale. Therefore, you might encounter
more bugs as usual.
- If you connect to an X.25 neighbour not operated by yourself, ASK the
other side first. Be prepared that bugs in the protocol implementation
might result in problems.
- This implementation has never wiped out my whole hard disk yet. But as
this is experimental code, don't blame me if that happened to you.
Backing up important data will never harm.
- Monitor your isdn connections while using this software. This should
prevent you from undesired phone bills in case of driver problems.
How to configure the kernel
===========================
The ITU-T (former CCITT) X.25 network protocol layer has been implemented
in the Linux source tree since version 2.1.16. The isdn subsystem might be
useful to run X.25 on top of ISDN. If you want to try it, select
"CCITT X.25 Packet Layer"
from the networking options as well as
"ISDN Support" and "X.25 PLP on Top of ISDN"
from the ISDN subsystem options when you configure your kernel for
compilation. You currently also need to enable
"Prompt for development and/or incomplete code/drivers" from the
"Code maturity level options" menu. For the x25trace utility to work
you also need to enable "Packet socket".
For local testing it is also recommended to enable the isdnloop driver
from the isdn subsystem's configuration menu.
For testing, it is recommended that all isdn drivers and the X.25 PLP
protocol are compiled as loadable modules. Like this, you can recover
from certain errors by simply unloading and reloading the modules.
What's it for? How to use it?
=============================
X.25 on top of isdn might be useful with two different scenarios:
- You might want to access a public X.25 data network from your Linux box.
You can use i4l if you were physically connected to the X.25 switch
by an ISDN B-channel (leased line as well as dial up connection should
work).
This corresponds to ITU-T recommendation X.31 Case A (circuit-mode
access to PSPDN [packet switched public data network]).
NOTE: X.31 also covers a Case B (access to PSPDN via virtual
circuit / packet mode service). The latter mode (which in theory
also allows using the D-channel) is not supported by isdn4linux.
It should however be possible to establish such packet mode connections
with certain active isdn cards provided that the firmware supports X.31
and the driver exports this functionality to the user. Currently,
the AVM B1 driver is the only driver which does so. (It should be
possible to access D-channel X.31 with active AVM cards using the
CAPI interface of the AVM-B1 driver).
- Or you might want to operate certain ISDN teleservices on your linux
box. A lot of those teleservices run on top of the ISO-8208
(DTE-DTE mode) network layer protocol. ISO-8208 is essentially the
same as ITU-T X.25.
Popular candidates of such teleservices are EUROfile transfer or any
teleservice applying ITU-T recommendation T.90.
To use the X.25 protocol on top of isdn, just create an isdn network
interface as usual, configure your own and/or peer's ISDN numbers,
and choose x25iface encapsulation by
isdnctrl encap <iface-name> x25iface.
Once encap is set like this, the device can be used by the X.25 packet layer.
All the stuff needed for X.25 is implemented inside the isdn link
level (mainly isdn_net.c and some new source files). Thus, it should
work with every existing HL driver. I was able to successfully open X.25
connections on top of the isdnloop driver and the hisax driver.
"x25iface"-encapsulation bypasses demand dialing. Dialing will be
initiated when the upper (X.25 packet) layer requests the lapb datalink to
be established. But hangup timeout is still active. Whenever a hangup
occurs, all existing X.25 connections on that link will be cleared
It is recommended to use sufficiently large hangup-timeouts for the
isdn interfaces.
In order to set up a conforming protocol stack you also need to
specify the proper l2_prot parameter:
To operate in ISO-8208 X.25 DTE-DTE mode, use
isdnctrl l2_prot <iface-name> x75i
To access an X.25 network switch via isdn (your linux box is the DTE), use
isdnctrl l2_prot <iface-name> x25dte
To mimic an X.25 network switch (DCE side of the connection), use
isdnctrl l2_prot <iface-name> x25dce
However, x25dte or x25dce is currently not supported by any real HL
level driver. The main difference between x75i and x25dte/dce is that
x25d[tc]e uses fixed lap_b addresses. With x75i, the side which
initiates the isdn connection uses the DTE's lap_b address while the
called side used the DCE's lap_b address. Thus, l2_prot x75i might
probably work if you access a public X.25 network as long as the
corresponding isdn connection is set up by you. At least one test
was successful to connect via isdn4linux to an X.25 switch using this
trick. At the switch side, a terminal adapter X.21 was used to connect
it to the isdn.
How to set up a test installation?
==================================
To test X.25 on top of isdn, you need to get
- a recent version of the "isdnctrl" program that supports setting the new
X.25 specific parameters.
- the x25-utils-2.X package from
ftp://ftp.hes.iki.fi/pub/ham/linux/ax25/x25utils-*
(don't confuse the x25-utils with the ax25-utils)
- an application program that uses linux PF_X25 sockets (some are
contained in the x25-util package).
Before compiling the user level utilities make sure that the compiler/
preprocessor will fetch the proper kernel header files of this kernel
source tree. Either make /usr/include/linux a symbolic link pointing to
this kernel's include/linux directory or set the appropriate compiler flags.
When all drivers and interfaces are loaded and configured you need to
ifconfig the network interfaces up and add X.25-routes to them. Use
the usual ifconfig tool.
ifconfig <iface-name> up
But a special x25route tool (distributed with the x25-util package)
is needed to set up X.25 routes. I.e.
x25route add 01 <iface-name>
will cause all x.25 connections to the destination X.25-address
"01" to be routed to your created isdn network interface.
There are currently no real X.25 applications available. However, for
tests, the x25-utils package contains a modified version of telnet
and telnetd that uses X.25 sockets instead of tcp/ip sockets. You can
use those for your first tests. Furthermore, you might check
ftp://ftp.hamburg.pop.de/pub/LOCAL/linux/i4l-eft/ which contains some
alpha-test implementation ("eftp4linux") of the EUROfile transfer
protocol.
The scripts distributed with the eftp4linux test releases might also
provide useful examples for setting up X.25 on top of isdn.
The x25-utility package also contains an x25trace tool that can be
used to monitor X.25 packets received by the network interfaces.
The /proc/net/x25* files also contain useful information.

ISDN-ABC-DW Extension
CONFIG_ISDN_WITH_ABC
These are many brand new Options and Features for the
ISDN SUBSYSTEM. Including Logical Device bindings,
Compression and other good stuff for Optimizing your
ISDN System.
To Use this Extensions you MUST HAVE THE NEWEST
ISDN4K-UTILS. You must have Version 3.1-Beta6 or
higher. Elsewhere you can not configure this Extensions.
WARNING ! THIS STUF IS NOT PRODUCTION RELEASE THE
FUNCTION ARE UNDER DEVELOPMENT. This ist BETA-CODE.
You can use it at you Own Risk.
For more Information on these Extensions take a look at
"linux/Documentation/isdn/dw-abc-extension-howto.txt or
Online at the Web "http://www.mediatronix.de/i4l/index.html"
Please Report Bugs to "mario@mediatronix.de" or
"delefw@isdn4linux.de"
D-Channel-Callback with Channel in use check
CONFIG_ISDN_WITH_ABC_CALLB
When a Interface is declared as an Callback Interface,
the Interface is checking that the other Side is not
Calling on the same time before the Interface is Dialing.
See "linux/Documentation/isdn/dw-abc-extension-howto.txt"
for more Information
In most case answer with "Yes" when you have Callback devices,
otherwise leave it "No"
Outgoing-EAZ-Support
CONFIG_ISDN_WITH_ABC_OUTGOING_EAZ
Enables the Feature to Define an other EAZ or MSN for
Outgoing calls on an Interface.
See "linux/Documentation/isdn/dw-abc-extension-howto.txt"
for more Information
Least Cost Router Support
CONFIG_ISDN_WITH_ABC_LCR_SUPPORT
This is the final Kernel Code for configuring an Least
Cost Router Softwarebased. The other Job is to do the
action in ISDNLOG. You need the ISDNLOG to use this
function. Currently the ISDNLOG have not the Support for
this Option.
So in most situations let the Option off.
TCP keepalive detect and response
CONFIG_ISDN_WITH_ABC_IPV4_TCP_KEEPALIVE
This Option works only with the TCP/IP V4. It enables
the Function that ISDN Devices are Answering TCP_KEEPALIVE Pakets
localy. So that TCP KEEPALIVE Pakets not longer takes the Line
open.
Drop frames Sourceadresse is not Interfaceadress
CONFIG_ISDN_WITH_ABC_IPV4_DYNADDR
This Option works only with the TCP/IP V4. It will allow only
the Transmitt of Pakets where the Sourceadresse is the Interface
adress. It is usefull when you have Lines with Dynamic IP.
See "linux/Documentation/isdn/dw-abc-extension-howto.txt"
for more Information
Receive do not reset the Hanguptimer
CONFIG_ISDN_WITH_ABC_RCV_NO_HUPTIMER
When you activate this option than the reiceive of pakets do
not reset the Hanguptimer. It is very usefull because if the
Paket vor your Network your Network generate an Response and
the Transmit is reseting the HUPTIMER. But when the Paket is
Rejected at your firewall your network generate no Response
and no Sendtraffic is generated. So in this case there is no
need to Reset the Huptimer because you have only received Data.
With that option only Transmitted Data/Pakets will reset the
HUPTIMER.
Support of (device-channel) and Binding Groups
CONFIG_ISDN_WITH_ABC_ICALL_BIND
This Option enables the Feature to Bind logical ISDN Interfaces
to an prefered ISDN Card or ISDN Card plus Channel. So you have
the Chance to keep Channels exclusively for one (or more)
Connection. Very usefull when you have more channels and Use
Calling Line Identification, because you can organize that your
call is going out over the Line with the right EAZ for the CLI.
Skip channel if used external (Dial Only)
CONFIG_ISDN_WITH_ABC_CH_EXTINUSE
When you have more than One ISDN Card in your System and you
will Dialout with an Interface you can become the Situation
that an External Device such a Telephone or Fax is Using the
B-Channels. Normaly ISDN4Linux does not detect this Situation
and dial everytime of the "External Busy" line out. With this
Option Enabled the I4L will detect that he can not dialout on
This Card and dial over the next Card out.
See "linux/Documentation/isdn/dw-abc-extension-howto.txt"
for more Information
Interface autodisable if Config error
CONFIG_ISDN_WITH_ABC_CONN_ERROR
This Option will detect an Device which generate Telephone
Cost but does not Function correctly because there are
Configerrors on one of the Site. In this Situation the
Interface will be marked as Unsuably for some time to do
not call every time this Site.
See "linux/Documentation/isdn/dw-abc-extension-howto.txt"
for more Information
UDP-Info-Support
CONFIG_ISDN_WITH_ABC_UDP_CHECK
This is the Mainoption to Enable or Disable the UDP
Info Support. An Option to Controll ISDN-Interfaces
Remotely. For this very Complex thing take a look at
"linux/Documentation/isdn/dw-abc-extension-howto.txt"
for more Information.
UDP Hangup Support
CONFIG_ISDN_WITH_ABC_UDP_CHECK_HANGUP
Sorry no more Information!
See "linux/Documentation/isdn/dw-abc-extension-howto.txt"
for more Information
UDP Dial Support
CONFIG_ISDN_WITH_ABC_UDP_CHECK_DIAL
Sorry no more Information!
See "linux/Documentation/isdn/dw-abc-extension-howto.txt"
for more Information
Limit on the line frames to two
CONFIG_ISDN_WITH_ABC_FRAME_LIMIT
This Option enables support for sending only 2 Pakets on
the Fly to the ISDN Driver. It is very usefull when you
will use the new RAW-IP Compression. Because of sending
Only 2 Pakets on the Fly makes the risk of overflowing
the ISDN Driver very smaller.
See "linux/Documentation/isdn/dw-abc-extension-howto.txt"
for more Information
Compression with RAWIP and X75I
CONFIG_ISDN_WITH_ABC_RAWIPCOMPRESS
With this Option you have the ability to make Datacompression
on RAW-IP Lines. It is function on HDLC and X75I Connection,
but the Prefered L2-Protocol for Compression is X75I because
the HDLC Protocol have no Errorcorrection.
To Use this Option YOU MUST HAVE ENABLED THE OPTION:
Support synchronous PPP
and must load after loading the main isdndrivers the
Modul "isdn_bsdcomp".

simple isdn4linux PPP FAQ .. to be continued .. not 'debugged'
-------------------------------------------------------------------
Q01: what's pppd, ipppd, syncPPP, asyncPPP ??
Q02: error message "this system lacks PPP support"
Q03: strange information using 'ifconfig'
Q04: MPPP?? What's that and how can I use it ...
Q05: I tried MPPP but it doesn't work
Q06: can I use asynchronous PPP encapsulation with network devices
Q07: A SunISDN machine can't connect to my i4l system
Q08: I wanna talk to several machines, which need different configs
Q09: Starting the ipppd, I get only error messages from i4l
Q10: I wanna use dynamic IP address assignment
Q11: I can't connect. How can I check where the problem is.
Q12: How can I reduce login delay?
-------------------------------------------------------------------
Q01: pppd, ipppd, syncPPP, asyncPPP .. what is that ?
what should I use?
A: The pppd is for asynchronous PPP .. asynchronous means
here, the framing is character based. (e.g when
using ttyI* or tty* devices)
The ipppd handles PPP packets coming in HDLC
frames (bit based protocol) ... The PPP driver
in isdn4linux pushes all IP packets direct
to the network layer and all PPP protocol
frames to the /dev/ippp* device.
So, the ipppd is a simple external network
protocol handler.
If you login into a remote machine using the
/dev/ttyI* devices and then enable PPP on the
remote terminal server -> use the 'old' pppd
If your remote side immediately starts to send
frames ... you probably connect to a
syncPPP machine .. use the network device part
of isdn4linux with the 'syncppp' encapsulation
and make sure, that the ipppd is running and
connected to at least one /dev/ippp*. Check the
isdn4linux manual on how to configure a network device.
--
Q02: when I start the ipppd .. I only get the
error message "this system lacks PPP support"
A: check that at least the device 'ippp0' exists.
(you can check this e.g with the program 'ifconfig')
The ipppd NEEDS this device under THIS name ..
If this device doesn't exists, use:
isdnctrl addif ippp0
isdnctrl encap ippp0 syncppp
... (see isdn4linux doc for more) ...
A: Maybe you have compiled the ipppd with another
kernel source tree than the kernel you currently
run ...
--
Q03: when I list the netdevices with ifconfig I see, that
my ISDN interface has a HWaddr and IRQ=0 and Base
address = 0
A: The device is a fake ethernet device .. ignore IRQ and baseaddr
You need the HWaddr only for ethernet encapsulation.
--
Q04: MPPP?? What's that and how can I use it ...
A: MPPP or MP or MPP (Warning: MP is also an
acronym for 'Multi Processor') stands for
Multi Point to Point and means bundling
of several channels to one logical stream.
To enable MPPP negotiation you must call the
ipppd with the '+mp' option.
You must also configure a slave device for
every additional channel. (see the i4l manual
for more)
To use channel bundling you must first activate
the 'master' or initial call. Now you can add
the slave channels with the command:
isdnctrl addlink <device>
e.g:
isdnctrl addlink ippp0
This is different from other encapsulations of
isdn4linux! With syncPPP, there is no automatic
activation of slave devices.
--
Q05: I tried MPPP but it doesn't work .. the ipppd
writes in the debug log something like:
.. rcvd [0][proto=0x3d] c0 00 00 00 80 fd 01 01 00 0a ...
.. sent [0][LCP ProtRej id=0x2 00 3d c0 00 00 00 80 fd 01 ...
A: you forgot to compile MPPP/RFC1717 support into the
ISDN Subsystem. Recompile with this option enabled.
--
Q06: can I use asynchronous PPP encapsulation
over the network interface of isdn4linux ..
A: No .. that's not possible .. Use the standard
PPP package over the /dev/ttyI* devices. You
must not use the ipppd for this.
--
Q07: A SunISDN machine tries to connect my i4l system,
which doesn't work.
Checking the debug log I just saw garbage like:
!![ ... fill in the line ... ]!!
A: The Sun tries to talk asynchronous PPP ... i4l
can't understand this ... try to use the ttyI*
devices with the standard PPP/pppd package
A: (from Alexanter Strauss: )
!![ ... fill in mail ]!!
--
Q08: I wanna talk to remote machines, which need
a different configuration. The only way
I found to do this is to kill the ipppd and
start a new one with another config to connect
to the second machine.
A: you must bind a network interface explicitly to
an ippp device, where you can connect a (for this
interface) individually configured ipppd.
--
Q09: When I start the ipppd I only get error messages
from the i4l driver ..
A: When starting, the ipppd calls functions which may
trigger a network packet. (e.g gethostbyname()).
Without the ipppd (at this moment, it is not
fully started) we can't handle this network request.
Try to configure hostnames necessary for the ipppd
in your local /etc/hosts file or in a way, that
your system can resolve it without using an
isdn/ippp network-interface.
--
Q10: I wanna use dynamic IP address assignment ... How
must I configure the network device.
A: At least you must have a route which forwards
a packet to the ippp network-interface to trigger
the dial-on-demand.
A default route to the ippp-interface will work.
Now you must choose a dummy IP address for your
interface.
If for some reason you can't set the default
route to the ippp interface, you may take any
address of the subnet from which you expect your
dynamic IP number and set a 'network route' for
this subnet to the ippp interface.
To allow overriding of the dummy address you
must call the ipppd with the 'ipcp-accept-local' option.
A: You must know, how the ipppd gets the addresses it wanna
configure. If you don't give any option, the ipppd
tries to negotiate the local host address!
With the option 'noipdefault' it requests an address
from the remote machine. With 'useifip' it gets the
addresses from the net interface. Or you set the address
on the option line with the <a.b.c.d:e.f.g.h> option.
Note: the IP address of the remote machine must be configured
locally or the remote machine must send it in an IPCP request.
If your side doesn't know the IP address after negotiation, it
closes the connection!
You must allow overriding of address with the 'ipcp-accept-*'
options, if you have set your own or the remote address
explicitly.
A: Maybe you try these options .. e.g:
/sbin/ipppd :$REMOTE noipdefault /dev/ippp0
where REMOTE must be the address of the remote machine (the
machine, which gives you your address)
--
Q11: I can't connect. How can I check where the problem is.
A: A good help log is the debug output from the ipppd...
Check whether you can find there:
- only a few LCP-conf-req SENT messages (less then 10)
and then a Term-REQ:
-> check whether your ISDN card is well configured
it seems, that your machine doesn't dial
(IRQ,IO,Proto, etc problems)
Configure your ISDN card to print debug messages and
check the /dev/isdnctrl output next time. There
you can see, whether there is activity on the card/line.
- there are at least a few RECV messages in the log:
-> fine: your card is dialing and your remote machine
tries to talk with you. Maybe only a missing
authentication. Check your ipppd configuration again.
- the ipppd exits for some reason:
-> not good ... check /var/adm/syslog and /var/adm/daemon.
Could be a bug in the ipppd.
--
Q12: How can I reduce login delay?
A: Log a login session ('debug' log) and check which options
your remote side rejects. Next time configure your ipppd
to not negotiate these options. Another 'side effect' is, that
this increases redundancy. (e.g your remote side is buggy and
rejects options in a wrong way).

"preparser" is a little tool to resolve special macros and conditional
preprocessor code in C files.
The special marcro and conditions are given in a control file.
The control file use the same syntax like the C preprocessor directives
"#define" and "#undef" plus a "#delete" command.
You can also use C-Comments in it.
Here are 2 implicit conditional defines in "preparser" for "#if 0"
and "#if 1" code segments.
Control file syntax:
#delete <item to delete>
#define <name> <value>
#undef <name>
<name> maybe also a function.
/* example control file */
#delete #include <linux/isdn_compat.h>
#define GET_USER get_user
#define PUT_USER put_user
#define idev_kfree_skb(a,b) dev_kfree_skb(a)
#define COMPAT_HAS_NEW_SYMTAB
#undef COMPAT_HAS_NEW_SETUP
/* end of example control file */
What does the Programm ?
1. It copies a input file into a output file (or stdout)
2. While copying it deletes all items given in #delete (exact string
matching).
3. While copying it resolve the marcros given in the control file.
4. It resolve any "#ifdef" "#ifndef" "#if" related to the marcros given in
the control file. Note: in the moment it don't calculate a value after
an "#if" directive, if here is a "#define" in the control file for
the string after "#if" and the value of that "#define" is empty, "#if" is
handled as false, if a value is given it is handled as true.
5. All items inside "strings" or C comments are not modified.
Usage
./preparser [options] <input file> [output file]
Valid options are:
-d increase debug level
-c,-C <controlfile> Use control file
-? Usage ; printout this information
"preparser" was written to write Linux portable Linux kernel code (portable
in the sense "portable between various kernel versions") and to remove
experimental code from C files. This avoid that contructs based on
KERNELVERSION are going into standard kernel.

# Makefile for the CAPI and AVM-B1 device drivers.
#
# Note! Dependencies are done automagically by 'make dep', which also
# removes any old dependencies. DON'T put your own dependencies here
# unless it's something special (ie not a .c file).
#
# Note 2! The CFLAGS definitions are now inherited from the
# parent makes..
#
# $Log$
# Revision 1.10 2000/03/03 16:48:38 calle
# - Added CAPI2.0 Middleware support (CONFIG_ISDN_CAPI)
# It is now possible to create a connection with a CAPI2.0 applikation
# and than to handle the data connection from /dev/capi/ (capifs) and also
# using async or sync PPP on this connection.
# The two major device number 190 and 191 are not confirmed yet,
# but I want to save the code in cvs, before I go on.
#
# Revision 1.9 2000/03/03 15:50:42 calle
# - kernel CAPI:
# - Changed parameter "param" in capi_signal from __u32 to void *.
# - rewrote notifier handling in kcapi.c
# - new notifier NCCI_UP and NCCI_DOWN
# - User CAPI:
# - /dev/capi20 is now a cloning device.
# - middleware extentions prepared.
# - capidrv.c
# - locking of list operations and module count updates.
#
# Revision 1.8 2000/01/25 14:33:38 calle
# - Added Support AVM B1 PCI V4.0 (tested with prototype)
# - splitted up t1pci.c into b1dma.c for common function with b1pciv4
# - support for revision register
#
# Revision 1.7 1999/09/15 08:16:03 calle
# Implementation of 64Bit extention complete.
#
# Revision 1.6 1999/07/20 06:41:44 calle
# Bugfix: After the redesign of the AVM B1 driver, the driver didn't even
# compile, if not selected as modules.
#
# Revision 1.5 1999/07/01 15:26:20 calle
# complete new version (I love it):
# + new hardware independed "capi_driver" interface that will make it easy to:
# - support other controllers with CAPI-2.0 (i.e. USB Controller)
# - write a CAPI-2.0 for the passive cards
# - support serial link CAPI-2.0 boxes.
# + wrote "capi_driver" for all supported cards.
# + "capi_driver" (supported cards) now have to be configured with
# make menuconfig, in the past all supported cards where included
# at once.
# + new and better informations in /proc/capi/
# + new ioctl to switch trace of capi messages per controller
# using "avmcapictrl trace [contr] on|off|...."
# + complete testcircle with all supported cards and also the
# PCMCIA cards (now patch for pcmcia-cs-3.0.13 needed) done.
#
# Revision 1.4 1997/03/30 17:10:40 calle
# added support for AVM-B1-PCI card.
#
# Revision 1.3 1997/03/22 02:00:57 fritz
# -Reworked toplevel Makefile. From now on, no different Makefiles
# for standalone- and in-kernel-compilation are needed any more.
# -Added local Rules.make for above reason.
# -Experimental changes in teles3.c for enhanced IRQ-checking with
# 2.1.X and SMP kernels.
# -Removed diffstd-script, same functionality is in stddiff -r.
# -Enhanced scripts std2kern and stddiff.
#
# Revision 1.1 1997/03/05 21:26:14 fritz

*
* $Log$
* Revision 1.6 1999/11/05 16:38:01 calle
* Cleanups before kernel 2.4:
* - Changed all messages to use card->name or driver->name instead of
* constant string.
* - Moved some data from struct avmcard into new struct avmctrl_info.
* Changed all lowlevel capi driver to match the new structur.
*
* Revision 1.5 1999/09/07 09:02:53 calle
* SETDATA removed. Now inside the kernel the datapart of DATA_B3_REQ and
* DATA_B3_IND is always directly after the CAPI message. The "Data" member
* ist never used inside the kernel.
*
* Revision 1.4 1999/08/04 10:10:08 calle
* Bugfix: corrected /proc functions, added structure for new AVM cards.
*
* Revision 1.3 1999/07/23 08:41:47 calle
* prepared for new AVM cards.
*
* Revision 1.2 1999/07/05 15:09:45 calle
* - renamed "appl_release" to "appl_released".
* - version und profile data now cleared on controller reset
* - extended /proc interface, to allow driver and controller specific
* informations to include by driver hackers.
*
* Revision 1.1 1999/07/01 15:26:22 calle

* $Id$
*
* Common module for AVM B1 cards.
*
* (c) Copyright 1999 by Carsten Paeth (calle@calle.in-berlin.de)
*
* $Log$
* Revision 1.12 1999/11/05 16:38:01 calle
* Cleanups before kernel 2.4:
* - Changed all messages to use card->name or driver->name instead of
* constant string.
* - Moved some data from struct avmcard into new struct avmctrl_info.
* Changed all lowlevel capi driver to match the new structur.
*
* Revision 1.11 1999/10/11 22:04:12 keil
* COMPAT_NEED_UACCESS (no include in isdn_compat.h)
*
* Revision 1.10 1999/09/15 08:16:03 calle
* Implementation of 64Bit extention complete.
*
* Revision 1.9 1999/09/07 09:02:53 calle
* SETDATA removed. Now inside the kernel the datapart of DATA_B3_REQ and
* DATA_B3_IND is always directly after the CAPI message. The "Data" member
* ist never used inside the kernel.
*
* Revision 1.8 1999/08/22 20:26:22 calle
* backported changes from kernel 2.3.14:
* - several #include "config.h" gone, others come.
* - "struct device" changed to "struct net_device" in 2.3.14, added a
* define in isdn_compat.h for older kernel versions.
*
* Revision 1.7 1999/08/04 10:10:09 calle
* Bugfix: corrected /proc functions, added structure for new AVM cards.
*
* Revision 1.6 1999/07/23 08:51:04 calle
* small fix and typo in checkin before.
*
* Revision 1.5 1999/07/23 08:41:48 calle
* prepared for new AVM cards.
*
* Revision 1.4 1999/07/09 15:05:38 keil
* compat.h is now isdn_compat.h
*
* Revision 1.3 1999/07/06 07:41:59 calle
* - changes in /proc interface
* - check and changed calls to [dev_]kfree_skb and [dev_]alloc_skb.
*
* Revision 1.2 1999/07/05 15:09:47 calle
* - renamed "appl_release" to "appl_released".
* - version und profile data now cleared on controller reset
* - extended /proc interface, to allow driver and controller specific
* informations to include by driver hackers.
*
* Revision 1.1 1999/07/01 15:26:23 calle
* complete new version (I love it):
* + new hardware independed "capi_driver" interface that will make it easy to:
* - support other controllers with CAPI-2.0 (i.e. USB Controller)
* - write a CAPI-2.0 for the passive cards
* - support serial link CAPI-2.0 boxes.
* + wrote "capi_driver" for all supported cards.
* + "capi_driver" (supported cards) now have to be configured with
* make menuconfig, in the past all supported cards where included
* at once.
* + new and better informations in /proc/capi/
* + new ioctl to switch trace of capi messages per controller
* using "avmcapictrl trace [contr] on|off|...."
* + complete testcircle with all supported cards and also the
* PCMCIA cards (now patch for pcmcia-cs-3.0.13 needed) done.
*

*
* $Log$
* Revision 1.6 2000/01/25 14:37:39 calle
* new message after successfull detection including card revision and
* used resources.
*
* Revision 1.5 1999/11/05 16:38:01 calle
* Cleanups before kernel 2.4:
* - Changed all messages to use card->name or driver->name instead of
* constant string.
* - Moved some data from struct avmcard into new struct avmctrl_info.
* Changed all lowlevel capi driver to match the new structur.
*
* Revision 1.4 1999/08/22 20:26:24 calle
* backported changes from kernel 2.3.14:
* - several #include "config.h" gone, others come.
* - "struct device" changed to "struct net_device" in 2.3.14, added a
* define in isdn_compat.h for older kernel versions.
*
* Revision 1.3 1999/07/09 15:05:40 keil

* Module for AVM B1 PCI-card.
*
* (c) Copyright 1999 by Carsten Paeth (calle@calle.in-berlin.de)
*
* $Log$
* Revision 1.19 2000/01/25 14:33:38 calle
* - Added Support AVM B1 PCI V4.0 (tested with prototype)
* - splitted up t1pci.c into b1dma.c for common function with b1pciv4
* - support for revision register
*
* Revision 1.18 1999/11/05 16:38:01 calle
* Cleanups before kernel 2.4:
* - Changed all messages to use card->name or driver->name instead of
* constant string.
* - Moved some data from struct avmcard into new struct avmctrl_info.
* Changed all lowlevel capi driver to match the new structur.
*
* Revision 1.17 1999/10/05 06:50:07 calle
* Forgot SA_SHIRQ as argument to request_irq.
*
* Revision 1.16 1999/08/11 21:01:07 keil
* new PCI codefix
*
* Revision 1.15 1999/08/10 16:02:27 calle
* struct pci_dev changed in 2.3.13. Made the necessary changes.
*
* Revision 1.14 1999/07/09 15:05:41 keil
* compat.h is now isdn_compat.h
*
* Revision 1.13 1999/07/05 15:09:50 calle
* - renamed "appl_release" to "appl_released".
* - version und profile data now cleared on controller reset
* - extended /proc interface, to allow driver and controller specific
* informations to include by driver hackers.
*
* Revision 1.12 1999/07/01 15:26:29 calle
* complete new version (I love it):
* + new hardware independed "capi_driver" interface that will make it easy to:
* - support other controllers with CAPI-2.0 (i.e. USB Controller)
* - write a CAPI-2.0 for the passive cards
* - support serial link CAPI-2.0 boxes.
* + wrote "capi_driver" for all supported cards.
* + "capi_driver" (supported cards) now have to be configured with
* make menuconfig, in the past all supported cards where included
* at once.
* + new and better informations in /proc/capi/
* + new ioctl to switch trace of capi messages per controller
* using "avmcapictrl trace [contr] on|off|...."

* Module for AVM B1/M1/M2 PCMCIA-card.
*
* (c) Copyright 1999 by Carsten Paeth (calle@calle.in-berlin.de)
*
* $Log$
* Revision 1.6 2000/01/25 14:37:39 calle
* new message after successfull detection including card revision and
* used resources.
*
* Revision 1.5 1999/11/05 16:38:01 calle
* Cleanups before kernel 2.4:
* - Changed all messages to use card->name or driver->name instead of
* constant string.
* - Moved some data from struct avmcard into new struct avmctrl_info.
* Changed all lowlevel capi driver to match the new structur.
*
* Revision 1.4 1999/08/22 20:26:26 calle
* backported changes from kernel 2.3.14:
* - several #include "config.h" gone, others come.
* - "struct device" changed to "struct net_device" in 2.3.14, added a
* define in isdn_compat.h for older kernel versions.
*
* Revision 1.3 1999/07/09 15:05:41 keil
* compat.h is now isdn_compat.h
*
* Revision 1.2 1999/07/05 15:09:51 calle
* - renamed "appl_release" to "appl_released".
* - version und profile data now cleared on controller reset
* - extended /proc interface, to allow driver and controller specific
* informations to include by driver hackers.
*
* Revision 1.1 1999/07/01 15:26:30 calle
* complete new version (I love it):
* + new hardware independed "capi_driver" interface that will make it easy to:
* - support other controllers with CAPI-2.0 (i.e. USB Controller)
* - write a CAPI-2.0 for the passive cards
* - support serial link CAPI-2.0 boxes.
* + wrote "capi_driver" for all supported cards.
* + "capi_driver" (supported cards) now have to be configured with
* make menuconfig, in the past all supported cards where included
* at once.
* + new and better informations in /proc/capi/
* + new ioctl to switch trace of capi messages per controller
* using "avmcapictrl trace [contr] on|off|...."
* + complete testcircle with all supported cards and also the
* PCMCIA cards (now patch for pcmcia-cs-3.0.13 needed) done.

* Module for AVM T1 HEMA-card.
*
* (c) Copyright 1999 by Carsten Paeth (calle@calle.in-berlin.de)
*
* $Log$
* Revision 1.9 2000/01/25 14:37:39 calle
* new message after successfull detection including card revision and
* used resources.
*
* Revision 1.8 1999/11/05 16:38:01 calle
* Cleanups before kernel 2.4:
* - Changed all messages to use card->name or driver->name instead of
* constant string.
* - Moved some data from struct avmcard into new struct avmctrl_info.
* Changed all lowlevel capi driver to match the new structur.
*
* Revision 1.7 1999/09/15 08:16:03 calle
* Implementation of 64Bit extention complete.
*
* Revision 1.6 1999/09/07 09:02:53 calle
* SETDATA removed. Now inside the kernel the datapart of DATA_B3_REQ and
* DATA_B3_IND is always directly after the CAPI message. The "Data" member
* ist never used inside the kernel.
*
* Revision 1.5 1999/08/22 20:26:28 calle
* backported changes from kernel 2.3.14:
* - several #include "config.h" gone, others come.
* - "struct device" changed to "struct net_device" in 2.3.14, added a
* define in isdn_compat.h for older kernel versions.
*
* Revision 1.4 1999/07/09 15:05:50 keil
* compat.h is now isdn_compat.h
*
* Revision 1.3 1999/07/06 07:42:04 calle
* - changes in /proc interface
* - check and changed calls to [dev_]kfree_skb and [dev_]alloc_skb.
*
* Revision 1.2 1999/07/05 15:09:54 calle
* - renamed "appl_release" to "appl_released".
* - version und profile data now cleared on controller reset
* - extended /proc interface, to allow driver and controller specific
* informations to include by driver hackers.
*
* Revision 1.1 1999/07/01 15:26:44 calle
* complete new version (I love it):
* + new hardware independed "capi_driver" interface that will make it easy to:
* - support other controllers with CAPI-2.0 (i.e. USB Controller)
* - write a CAPI-2.0 for the passive cards
* - support serial link CAPI-2.0 boxes.
* + wrote "capi_driver" for all supported cards.
* + "capi_driver" (supported cards) now have to be configured with
* make menuconfig, in the past all supported cards where included
* at once.
* + new and better informations in /proc/capi/
* + new ioctl to switch trace of capi messages per controller
* using "avmcapictrl trace [contr] on|off|...."
* + complete testcircle with all supported cards and also the
* PCMCIA cards (now patch for pcmcia-cs-3.0.13 needed) done.

* (c) Copyright 1999 by Carsten Paeth (calle@calle.in-berlin.de)
*
* $Log$
* Revision 1.4 2000/01/25 14:33:38 calle
* - Added Support AVM B1 PCI V4.0 (tested with prototype)
* - splitted up t1pci.c into b1dma.c for common function with b1pciv4
* - support for revision register
*
* Revision 1.3 1999/11/13 21:27:16 keil
* remove KERNELVERSION
*
* Revision 1.2 1999/11/05 16:38:02 calle
* Cleanups before kernel 2.4:
* - Changed all messages to use card->name or driver->name instead of
* constant string.
* - Moved some data from struct avmcard into new struct avmctrl_info.
* Changed all lowlevel capi driver to match the new structur.
*
* Revision 1.1 1999/10/26 15:31:42 calle
* Added driver for T1-PCI card.

* Revision 1.4 1999/08/25 20:02:21 werner
* Changed return values for stat_icall(w) from 3->4 and 4->5 because of conflicts
* with existing software definitions. (PtP incomplete called party number)
*
* Revision 1.3 1999/08/22 20:26:35 calle
* backported changes from kernel 2.3.14:
* - several #include "config.h" gone, others come.
* - "struct device" changed to "struct net_device" in 2.3.14, added a
* define in isdn_compat.h for older kernel versions.
*
* Revision 1.2 1999/07/04 21:37:32 werner
* Ported from kernel version 2.0
