Objectives

We assume here that you want to make a connection to the internet using synchroneous ppp and that you use an internal passive ISDN card. The isdn4linux driver is documented for Euro ISDN

The setup is tested with different providers ( T-online, MSN, and my own ppp Server) on 486er and Pentium machines using the AVM Fritz and an Elsa Microlink card.

Specific questions conserning the Hisax driver can be looked up at the i4l faq and the Readme for Hisax

Special cases like canal bundeling, callback etc are not yet tested but should be possible. Refer to the hisax guide. Although the use of active cards, like the avm b1, is possible,it is not tested, and should require some extra work.

Users with external ISDN modems should look at the ppp dial up page..

Comments on this section should be addressed to its maintainer: Eric Wolzak .

Important

ISDN-cards connect quiet, and usually without any signs. If you have a wrongly configured machine on your network, you could experience a lot of undesired connections: you will not notice it until the next telephone bill!. So, especially for a start, check your messages file regulary. I use the beep.lrp which gives an audible signal on connecting. During the setup disconnect the ISDNline until you know that all other parts do function.
