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.
