+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"

+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

+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

+   HUPTIMER.

+   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.
