XCCTSP error on Cisco 1760 with ISDN-2 BRI and MGCP

[KronosNOC]

Hi all,

Somebody has seen this error message before?

Error- ISDN BRI backhaul XCCTSP created failed

This is happend when you will bind the ISDN-2 port to MGCP using "isdn bind-l3 ccm-manager service mgcp".

Can´t find anything on the forum..

Any suggestions?

TIA.

Don't believe BRI Backhaul is supported on the 1760.

Kevin,

Sorry it is 1760-V. And yes it is supported because it is working on other three ports of VIC2-BRI module.

But the fourth port issue the error!

Right, just checked feature navigator and it is supported on the 17xx platforms. The technote is not terribly clear on that :-(

Is layer 2 up on the affected BRI?

If it is up then I would recommend opening a TAC case to determine if there are any know issues with backhauling multiple BRIs.

Kevin,

Yes it is up but if you want to apply those command "isdn bind-l3...." you need to shut the port firs.

See below the log:

The weird thing is that this configuration has worked for more than two weeks and stops working suddently since this morning! At least the fourth port of it...
