Subject: [nsp] Cisco 802 ISDN config


below is the runing config for a cisco 802 ISDN router. We trying to
establish
a dialup connection to a cisco AS5300 to establish a 128k link (both
channels).

The following error is reported from the show log;
ISDN-6-LAYER2DOWN: Layer 2 for Interface BRI0, TEI 255 changed to down.

Not sure what I am missing here or what I have futsed in the config. Feel
free
to tear it apart.

Thank

Dave

> Dave, what does your show isdn status say?

Checked this, made some minor mods to the config and checked the spids, am
still not getting successful calls and am also getting this error occasionally;
//
00:15:24: %PQICC-1-LOSTCARR: Unit 0, lost carrier. Transceiver problem?
//


here is the result of the sh isdn stat and debug output of attempted call

repeats...


is the receiving line not accepting the digital call or not correctly configured
for it? It is a valid number used for analog dialup conenctions, and is a Cisco
AS5300 with PRIs in each port. This line

00:16:51546402884: Cause i = 0xE281 - Unallocated/unassigned number

leads me to believe that there is something wrong, perhaps in routing the call
to the box? no idea. Anyone have a clue?
