Hello,
I'm doing a test using a BRI back to back. using two(2) Cisco 2800 with VIC2-2BRI NT/TE.
After I've configured, I have this error on the router Network side.
I've already checked with IOS 12.4.24YB, 15.1.3T but no success. I have the same issue.
Is there any workaround? how to Check the clock source.
Below is the output of debug isdn q921.
