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.
