I have seen behavior like this that was caused by having the wrong
switch type configured. However, we had the wrong one configured
because we actually trusted Qwest! <g> They told us we had a 5ESS
switch which was partially true. In reality it was a 5ESS switch
running National ISDN software. In that situation you need to configure
a basic-ni1 switch type.
I don't know what the specific problem might be in your case, but it
might be something along those lines. If you don't know *for certain*
it might be worthwhile to check with your provider and verify the switch
type.
BTW, could we see the debug output as well as the output from "show
isdn status"?
Good luck,
John

Hello,
I am configuring Cisco 801 ISDN routers to link two offices together
via
dial-on-demand. The connection fails to even get to the CHAP
authentication
stage (tried PAP also). On debugging the connection attempts (debug
PPP
negotiation), it is clear that the failure is occuring at the LCP
stage.
Neither router is sending LCP configuration details. Whichever side
initiates the connection, there is no incoming request received in
response
to the outgoing conFREQ's and so the connection times-out after 24
seconds.
IOS version is 12 and ISDN connectivity is proven (basic net 3).
Can anyone help with where to look for the problem?
Thanks in advance.
Row.
