Red Hat ISDN config
1.ISDN Hardware Configuration
1.1 Type of your ISDN adapter
Choose your ISDN card from the list. If your card isn't shown there, you
can find additional information in the kernel documentation under
/usr/src/linux/Dokumentation/isdn/README.HiSax about configuring the
card by hand.
The ISDN cards AVM B1, IBM Active 2000 and PCBIT-D as well as all cards
of the manufacturers ICN, Eicon and SpellCaster can't be configured with
this tool. In this case, please read the appropriate files under
/usr/src/linux/Documentation/isdn!
Please keep in mind that isdn4linux was tested only with the listed ISDN
adapters. Others may work, but neither we do guarantee that nor do we
support them.
With most ISDN cards additional information about the hardware
settings is needed.
ISA PnP and PCMCIA cards must be configured with the appropriate tools
before the ISDN configuration. In this case the defaults for the
interrupt and the I/O address are PNP or PCMCIA. These must be adjusted
to the same values as in the PnP or PCMCIA configuration.
1.2 Interrupt
The IRQ that should be assigned to the card. The IRQ shouldn't yet
be used yet by other devices (cat /proc/pci) and the ISDN card should
also be able to use this IRQ.
1.3 I/O Port
The port on which the card receives commands from the computer and
exchanges data with it. The value must be noted in hexadecimal, e.g.
0x280.
1.4 Memory adress
Some cards don't exchange the data over the input/output port, but
over a certain memory area. The memory address must be noted in
hexadecimal, e.g. 0xd0000.
1.5 Plug & Play / PCMCIA
ISA PnP and PCMCIA cards must be configured with the appropriate tools
before the ISDN configuration. In this case the defaults for the
interrupt and the I/O address are PNP or PCMCIA. These must be adjusted
to the same values as in the PnP or PCMCIA configuration.
1.6 ISDN-Protocol
Nowadays new lines are only assigned with the protocol EDSS1. However
sometimes with older telephone systems it can be necessary to change
the protocol over to 1TR6. The documentation of the telephone system
contains more exact information about the used protocol.
