I am having an issue with fax machines connecting and transmitting.
I have a 2821 router with 4 total PRI connections.
2 connections go to a Mitel PBX and 2 go to the PSTN.
I have a fax machine on the Mitel side try to fax and it fails. If I do a show controllers t1, I see a ton of frame errors on the PRI's to the PBX but not on the PSTN PRI's.
If I switch the clock select from the backplane to on of the PBX PRI's, the PSTN PRI's start throwing errors.
How can I configure these clock sources?

You should have pstn line clocking and select, pbx clock internal, participate but no select.

Can you explain this further?
0/0/0 and 0/0/1 are to the PSTN
0/1/0 and 0/1/1 are to the PBX.

pstn lines use line clock and select, pbx internal clock and participate only.
