You can get the ICN-ISDN-card from:

Thinking Objects Software GmbH
Obere Heerbergstr. 17
97078 W�rzburg
Tel: +49 931 2877950
Fax: +49 931 2877951

email info@think.de

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
      1  1  1  NOT ALLOWED!
