ISDN Terminal Adapter

SuSE Linux: Versions 6.1 to 7.3
Kernel: Versions since 2.2.x

Request:

You want to connect to the Internet with your ISDN terminal adapter using wvdial. If you own a PBX with computer interface for the Internet, skip to the section --> 'Note for PBX'.

Procedure:

ISDN terminal adapters behave slightly differently than normal analog modems. They need special commands to handle the point-to-point-protocol.

Therefore, the modem configuration as described in the manual (chapter Configuration of wvdial) must be adjusted.

Do not use the automatic modem detection, which could be launched

SuSE Linux Version 6.3 or higher

Launch YaST and choose the menu and select your terminal adapter.

Then adjust the name of the serial device using the item Serial Port:.

All further configuration steps should be done as described in the manual.

If your terminal adapter is not included in the list, enter the initstrings manually in the Expert menu.
For the first inittstring, the AT command that switches the terminal adapter to the asynchronous PPP mode must embedded in the following way: AT&F<PPP-AT-command>. The second initstring is emtpy.
The <PPP-AT-command> is not standardized and depends on the adapter type. Refer to the manual of the terminal adapter. Often it can be found with the keyword asyncPPP.

For example, the <PPP-AT-command> of the models ELSA MicroLink ISDN-EU and ELSA MicroLink ISDN Internet
is $IBP=HDLCP. Therefore the first initstring is

       Init String 1 (sent to modem first): "AT&F$IBP=HDLCP"
       
Find a list of known initstrings below.

We would appreciate feedback about your initstring, if it is not listed below.
