The icn, act2000 and pcbit drivers are all for very old hardware, and it is highly unlikely that anyone is actually still using them on modern kernels, if at all. All three drivers apparently are for hardware that predates PCI being the common connector, as they are ISA-only and active PCI ISDN cards were widely available in the 1990s. Looking through the git logs, it I cannot find any indication of a patch to any of these drivers that has been tested on real hardware, only cleanups or global API changes.

README file for the PCBIT-D Device Driver.
|
|
------------------------------------------------------------------------------
|
|
|
|
The PCBIT is a Euro ISDN adapter manufactured in Portugal by Octal and
|
|
developed in cooperation with Portugal Telecom and Inesc.
|
|
The driver interfaces with the standard kernel isdn facilities
|
|
originally developed by Fritz Elfert in the isdn4linux project.
|
|
|
|
The common versions of the pcbit board require a firmware that is
|
|
distributed (and copyrighted) by the manufacturer. To load this
|
|
firmware you need "pcbitctl" available on the standard isdn4k-utils
|
|
package or in the pcbit package available in:
|
|
|
|
ftp://ftp.di.fc.ul.pt/pub/systems/Linux/isdn
|
|
|
|
Known Limitations:
|
|
|
|
- The board reset procedure is at the moment incorrect and will only
|
|
allow you to load the firmware after a hard reset.
|
|
|
|
- Only HDLC in B-channels is supported at the moment. There is no
|
|
current support for X.25 in B or D channels nor LAPD in B
|
|
channels. The main reason is that these two other protocol modes have,
|
|
to my knowledge, very little use. If you want to see them implemented
|
|
*do* send me a mail.
|
|
|
|
- The driver often triggers errors in the board that I and the
|
|
manufacturer believe to be caused by bugs in the firmware. The current
|
|
version includes several procedures for error recovery that should
|
|
allow normal operation. Plans for the future include cooperation with
|
|
the manufacturer in order to solve this problem.

Information/hints/help can be obtained in the linux isdn
|
|
mailing list (isdn4linux@listserv.isdn4linux.de) or directly from me.
