I have an E1 PRI plugged into a cisco 5350. There are no other circuits attached to the router. The clock source is set to the line, and the tdm bus is set to use this port.
The cisco reports a huge amount of timing slip (300 to 400 Slip Secs per 900 sec interval). There are no other errors.
I do not have physical access to the router or circuit, but on-site staff has tested the circuit, and claim it tested good.
We are a US company, and this our first E1. Is there something special that needs to be configured?
What could be causing these errors? What should I be looking at?
thanks --jeff
