Likely cabling problem. However, you should use clock source internal when connecting PBX.

Router rarely fails.

Check cabling and configure internal clock.

Re: ROUTER E1 OR PABX E1 PROBLEM

one thing, the e1 configs are still intact on the configuration. doesnt this dictate that the hardware is okay?

controller E1 0/0/0

pri-group timeslots 1-31

interface Serial0/0/0:15

no ip address

encapsulation hdlc

isdn switch-type primary-net5

isdn incoming-voice voice

no cdp enable

No.

You can do loopback tests, but in most cases it's just wasting time, because the problem is something else.
