We have a customer who wants to install a Cisco 1004 ISDN router (to
replace an Ascend Pipeline).
We can only take DOSBS ISDN calls through the central office he calls
(the CO's DMS-100 switch is not equipped to provide PRI service).
We have not yet found the configuration commands needed to set up DOSBS.
The user appears to make a connection lasting about 22 seconds, but not
authenticate, and the call drops.
There is another potential problem: the user has probably set up his
router per the User Guide to authenticate using CHAP...we don't do CHAP
(although if necessary we could for this user). I only started looking
at that part of the issue this morning...presumably the
ppp authentication chap
statement in the example in the User Guide chan be changed to
ppp authentication pap
and I'll contact the user about that this morning.
Thanks for your help!
Note: the equipment taking the call on our end is a PortMaster 3 (our
Cisco AS5300 is used on other incoming T1s, but not the one the customer
comes in on). So Cisco NAS debugging command advice won't help here,
The primary cause of problems is solutions.
