Hey, got a quick question here. I configured a couple of point to point 1841 routers for a new WAN to our remote office. Everything worked fine when i tested them here. I shipped the remote router out, had it hooked up and the circuit came up instantly. I setup monitoring and that night got a lot of alerts saying the circuit was down. I checked it in the morning and on my side, the router had a lot of CRC errors. I made sure framing, linecode, encapsulation was all good. both sides are using the line clocking etc. Its a full t1 and after running extended ping tests with a lot of drops i figured the line wasnt clean. Well Verizon tested the circuit 2 times and they said it was good. Any ideas? here is a running config and a sh int. Also if i clear the counters the errors will start to increase again on this end. Thanks.
