I am trying to hand off a PRI to a Mitel phone system and I am having issues with Slips. This is the first time I have done it on the 4321 but I have accomplished this many times on 2800 & 2900's. The issue here is in the controller I am unable to set the clock source to internal while at the same time setting it as a PRI.
In the past my controller config looked like this:
controller T1 0/1/0
framing esf
clock source internal
linecode b8zs
cablelength short 110
pri-group timeslots 1-24
But on this 4321 I get an error when I try to set the PRI group with the clock source set to internal
%Cannot create ds0/tdm/pri-group with clock source internal
%pri-group voice-dsp cannot be created under the clock source configuration
Has anyone ever done this with a 4321 or have any ideas?
Here is the configuration without the clock source internal set. Also, I should mention that the network-clock sync is set to auto.
controller T1 0/1/0
framing esf
linecode b8zs
cablelength short 110
pri-group timeslots 1-24

I'm just getting back to this project. Wanted to give it a bump in case anyone has information.

I apologize but I'm not sure how I can elaborate any more than I already have in my very first post. Is there something more specific details you're looking for?

Ritesh,
Thank you for the reply, but in this case we are emulating the network to the phone system thus we have to be the clock source not the other way around. I do understand what you're saying but sadly in this case is not the solution. As stated above on the older 2800 and 2900 series ISRs I can set clock source internal which is what I want to do but the 4300 is giving me the error mentioned above

Hey Hi Douglas,
Refer to same URL as shared above with Title section:Configuring Cisco Fourth-Generation T1/E1 Voice and WAN Network Interface Module. Refer to Configuring the T1/E1 Network Interface Module for Data Support. Document mentions.
Specifies the clock source. The options are as follows:
internal—Sets the controller framer as the clock master.
The clock source internal command is only applicable with the channel-group command and the pri-group (for data) command.
Note: The pri-group command is supported on the NIM-xCE1T1-PRI for data without the keyword voice-dsp.
Can you check by doing this? Please try...

Ritesh,
I did read that document. The issue is this is a PRI voice circuit without Data. I am not sure now how to accomplish this without being able to set the clock source to internal. I can't imagine that Cisco has removed this type of support as they still allow the isdn protocol-emulate network under the serial interface.

The clocking command has changed with the ISR 4XXX Routers. Look at the posting below.
