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.
