ISDN getting no active line w/ Teles card

ISDN getting no active line w/ Teles card

Post by B.J. Recht » Tue, 27 Jan 1998 04:00:00

When trying to start the ippd for synchroneous ppp after confiuring an
ISDN interface with one of the example scripts from the ISDN4linux
package (version 2.0) the kernel starts printing warnings:
'kernel: isdn_ppp_bind: No usable ippd device'found.

Checking things with the telecom-provider showed that no valid packets
were in effect recognized by the telephone-exchange.
Strange thing is, that the duvox (also caled moduvox) working just fine
with the same S0-bus.

Things are configured to use the EURo/DSS1 protocol for ISDN, so that
shuold be right.

I am currently using kernel version 2.0.33. with the ISDN subsystem and
PP support compiled directly into thek ernel and the Hisax driver built
and used as module.
The Hisax driver loads without any problems and states that it has added
two channels.

Even trying to a dial with  minicom via the ttyI* devices resulted in
either 'BUSY'or 'No CARRIER'. ISDNlog di not show any information at all,
which suports the statement about invalid packets.

Question is ofcourse why the kernel is sending the wrong packets, thus
getting no answer from the telephone-exchange and the complaining about
no usable devices.

Any help in solving this strange problem is welcome.

1. I cant get my Teles ISDN card configured in linux

Does anybody know how I can configure the Teles ISDN BRI 16.3 card
into Linux? I have followed the instructions in the various README's
and HOWTO's, but I'm still confused. I cant get it right.
What should I do about the pppd stuff? Or should I use ipppd?
I have Slackware 3.0 with the kernel upgraded to 2.0.21.
I don't have very much experience in Linux, but I'm learning.

Thank You
