[c-nsp] Need some help: Cisco 2801 Router with G.703 and ADSL-Backup

[Florian Taeger]

Hello everyone,

I've got a Cisco 2801 Router with a VWIC-1MFT1E and a WIC-1ADSL-I-DG. I want
this Router to connect via G.703 Line to our Router and if this line fails, I
want the router to establish a dsl-link. Over this dsl-link, the router receivs
the same routed net as over the G.703 Line. Both, the serial-link and the
dsl-link are terminated on routers of mine.

The problem is: The G.703 Line (Serial 0/1/0:0) works fine. But if I pull the
plug of this line out of the router, the dsl-line does not establish the backup
link. The line itself works fine - I have tested it with another router. Can
anyone find the failure in the config listed below? And yes, I am sure, that I
need to use pap to authenticate with the dsl-gateway :)

If I want to connect to this router via telnet, I become the message "password
required, but not set". Why? I want the router to allow login for the user
listed in the "username <USER> password 7 <PASSWORD>" section.

Thank you for any help.

Best regards

Florian
