Configure 2911 PRI serial

Answered Question
Aug 5th, 2010

I have a 2911 router that I'm trying to configure a PRI interface for but under the Serial interface I do not see the isdn commands.

Attached is my config:

IOS=  c2900-universalk9-mz.SPA.151-1.T1.bin

Do I need different IOS, I looked on CCO with s'ware advisor and it tols me the version I'm using has it but can't figure out how to find them.


I have this problem too.

Your controller configuration is wrong; try a 'pri-group timeslots 1-24' instead.
