Driver for active AVM Controller
|
|
================================
|
|
|
|
The driver provides a kernel capi2.0 Interface (kernelcapi) and
|
|
on top of this a User-Level-CAPI2.0-interface (capi)
|
|
and a driver to connect isdn4linux with CAPI2.0 (capidrv).
|
|
The lowlevel interface can be used to implement a CAPI2.0
|
|
also for passive cards since July 1999.
|
|
|
|
The author can be reached at calle@calle.in-berlin.de.
|
|
The command avmcapictrl is part of the isdn4k-utils.
|
|
t4-files can be found at ftp://ftp.avm.de/cardware/b1/linux/firmware
|
|
|
|
Currently supported cards:
|
|
|
|
- B1 ISA (all versions)
|
|
- B1 PCI
|
|
- T1/T1B (HEMA card)
|
|
- M1
|
|
- M2
|
|
- B1 PCMCIA
|
|
|
|
Installing
|
|
----------
|
|
|
|
You need at least /dev/capi20 to load the firmware.
|
|
|
|
::
|
|
|
|
mknod /dev/capi20 c 68 0
|
|
mknod /dev/capi20.00 c 68 1
|
|
mknod /dev/capi20.01 c 68 2
|
|
.
|
|
.
|
|
.
|
|
mknod /dev/capi20.19 c 68 20
|
|
|
|
Running
|
|
-------
|
|
|
|
To use the card you need the t4-files to download the firmware.
|
|
AVM GmbH provides several t4-files for the different D-channel
|
|
protocols (b1.t4 for Euro-ISDN). Install these file in /lib/isdn.
|
|
|
|
if you configure as modules load the modules this way::
|
|
|
|
insmod /lib/modules/current/misc/capiutil.o
|
|
insmod /lib/modules/current/misc/b1.o
|
|
insmod /lib/modules/current/misc/kernelcapi.o
|
|
insmod /lib/modules/current/misc/capidrv.o
|
|
insmod /lib/modules/current/misc/capi.o
|
|
|
|
if you have an B1-PCI card load the module b1pci.o::
|
|
|
|
insmod /lib/modules/current/misc/b1pci.o
|
|
|
|
and load the firmware with::
|
|
|
|
avmcapictrl load /lib/isdn/b1.t4 1
|
|
|
|
if you have an B1-ISA card load the module b1isa.o
|
|
and add the card by calling::
|
|
|
|
avmcapictrl add 0x150 15
|
|
|
|
and load the firmware by calling::
|
|
|
|
avmcapictrl load /lib/isdn/b1.t4 1
|
|
|
|
if you have an T1-ISA card load the module t1isa.o
|
|
and add the card by calling::
|
|
|
|
avmcapictrl add 0x450 15 T1 0
|
|
|
|
and load the firmware by calling::
|
|
|
|
avmcapictrl load /lib/isdn/t1.t4 1
|
|
|
|
if you have an PCMCIA card (B1/M1/M2) load the module b1pcmcia.o
|
|
before you insert the card.
|
|
|

Leased Lines with B1
|
|
--------------------
|
|
|
|
Init card and load firmware.
|
|
|
|
For an D64S use "FV: 1" as phone number
|
|
|
|
For an D64S2 use "FV: 1" and "FV: 2" for multilink
|
|
or "FV: 1,2" to use CAPI channel bundling.
