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.
