Russell, If you are trying to setup a B2B, you have to use the channel-group command instead of pri-group.
Clock source internal is only supported when using channel-group.

When doing network side isdn to a pbx, you have to provide them the clock, I like Brian have not figured out that part of the 4K voodoo.

Performing an integration with a Nortel PBX (back to back PRI) where i need to be the clock source on the underlying T1 circuit. In the past on ISR G2 platforms (like a 2921), I could configure "clock source internal" under the controller T1 interface. On the 4331 I get the following error when the clock source it set to internal under the controller T1 TIV-4331-01-TEMP(config-controller)#pri-group timeslots 1-24 %Cannot create ds0/tdm/pri-group with clock source internal %pri-group voice-dsp cannot be created under the clock source configuration How do I accomplish the same on this newer platform or is it no longer possible ? The NIM does have it's own DSP resources. I can get the integration up and working, with the default "clock source line", but I get slips on the t1 as the Nortel side is free running and looking to the line as a clock source on its end. I hope I'm just missing something obvious.
