NAME
daic —
isdn4bsd driver for EICON.Diehl
active ISDN cards
SYNOPSIS
daic0 at isa? iomem 0xd8000 irq 10
DESCRIPTION
The
daic driver supports the old Diehl active cards:
S, SX, SXn, SCOM and
QUADRO.
For a
QUADRO card, the driver will detect the board type and
use all four ports, each attached as a controller of its own to the isdn4bsd
system, which can be listed using the daicctl utility.
The
daic driver interfaces the ISDN card to the ISDN4BSD
kernel subsystem. All lower layer ISDN control is handled by the card. This
should allow you to run any national ISDN protocol delivered by EICON.Diehl
for your card, but the driver has only been tested with the DSS1 protocol and
some parts of the cards interface are ISDN protocol dependent.
The
daic driver is written to conform to the software
interface documented by Diehl in their
ISDN-Karten
Benutzerhandbuch from 1992.
MICROCODE DOWNLOAD
Every active card needs its own operating software before it can work. You have
to download this to the card before using it with isdn4bsd. Use the daicctl
utility to do this, i.e. call
daicctl -d te_etsi.sx 1 to
download the file
te_etsi.sx to controller number 1. Use
daicctl -l to list all available controllers (and ports).
You have to select the correct ISDN protocol file for your ISDN interface, see
the Diehl documentation for details.
The cards bootstrap process involves another file, which is independent of the
card type you use and the protocol you run. It is called
download.bin in current versions of the Diehl software
distribution and has to be copied to the kernel compile directory under
dev/microcode/daic and converted into a header file used
when compiling the kernel by running
make in that directory.
Your kernel compile will fail and remind you of this if you forget to do this.
Due to copyright restrictions we cannot distribute the driver with this file
integrated. But if you own a card, you do have the file (or can get it from
the Diehl web server).
