You can get the ICN-ISDN-card from:
Thinking Objects Software GmbH

The card communicates with the PC by two interfaces:
1. A range of 4 successive port-addresses, whose base address can be
configured with the switches.
2. A memory window with 16KB-256KB size, which can be setup in 16k steps
over the whole range of 16MB. Isdn4linux only uses a 16k window.
The base address of the window can be configured when loading
the lowlevel-module (see README). If using more than one card,
all cards are mapped to the same window and activated as needed.
Setting up the IO-address dipswitches for the ICN-ISDN-card:
Two types of cards exist, one with dip-switches and one with
hook-switches.
1. Setting for the card with hook-switches:
(0 = switch closed, 1 = switch open)
S3 S2 S1 Base-address
0 0 0 0x300
0 0 1 0x310
0 1 0 0x320 (Default for isdn4linux)
0 1 1 0x330
1 0 0 0x340
1 0 1 0x350
1 1 0 0x360

2. Setting for the card with dip-switches:
(0 = switch closed, 1 = switch open)

The ICN driver may be built into the kernel or as a module. Initialization
depends on how the driver is built:
Driver built into the kernel:
The ICN driver can be configured using the commandline-feature while
loading the kernel with LILO or LOADLIN. It accepts the following syntax:
icn=p,m[,idstring1[,idstring2]]
where
p = portbase (default: 0x320)
m = shared memory (default: 0xd0000)
When using the ICN double card (4B), you MUST define TWO idstrings.
idstring must start with a character! There is no way for the driver
to distinguish between a 2B and 4B type card. Therefore, by supplying
TWO idstrings, you tell the driver that you have a 4B installed.
If you like to use more than one card, you can use the program
"icnctrl" from the utility-package to configure additional cards.
You need to configure shared memory only once, since the icn-driver
maps all cards into the same address-space.
Using the "icnctrl"-utility, portbase and shared memory can also be
changed during runtime.
The D-channel protocol is configured by loading different firmware
into the card's memory using the "icnctrl"-utility.
Driver built as module:
The module icn.o can be configured during "insmod'ing" it by
appending its parameters to the insmod-commandline. The following
syntax is accepted:
portbase=p membase=m icn_id=idstring [icn_id2=idstring2]
where p, m, idstring1 and idstring2 have the same meanings as the
parameters described for the kernel-version above.
When using the ICN double card (4B), you MUST define TWO idstrings.
idstring must start with a character! There is no way for the driver
to distinguish between a 2B and 4B type card. Therefore, by supplying
TWO idstrings, you tell the driver that you have a 4B installed.
Using the "icnctrl"-utility, the same features apply to the modularized
version like to the kernel-builtin one.
The D-channel protocol is configured by loading different firmware
into the card's memory using the "icnctrl"-utility.
Loading the firmware into the card:
The firmware is supplied together with the isdn4k-utils package. It
can be found in the subdirectory icnctrl/firmware/
There are 3 files:
loadpg.bin - Image of the bootstrap loader.
pc_1t_ca.bin - Image of firmware for german 1TR6 protocol.
pc_eu_ca.bin - Image if firmware for EDSS1 (Euro-ISDN) protocol.
Assuming you have installed the utility-package correctly, the firmware
will be downloaded into the 2B-card using the following command:
icnctrl -d Idstring load /etc/isdn/loadpg.bin /etc/isdn/pc_XX_ca.bin
where XX is either "1t" or "eu", depending on the D-Channel protocol
used on your S0-bus and Idstring is the Name of the card, given during
insmod-time or (for kernel-builtin driver) on the kernel commandline.
To load a 4B-card, the same command is used, except a second firmware
file is appended to the commandline of icnctrl.
-> After downloading firmware, the two LEDs at the back cover of the card
(ICN-4B: 4 LEDs) must be blinking intermittently now. If a connection
is up, the corresponding led is lit continuously.
For further documentation (adding more ICN-cards), refer to the manpage
icnctrl.8 which is included in the isdn4k-utils package.
