Hi,
Sometimes my routers loose connectivity, when I go back and I check their serial interfaces I see carrier transitions as well as interface resets.
When I use the show service-module serial command I have "Receiver has no alarms". My question is: How could I determine whether the problem is on my end or not? I am almost sure this is an ISP problem because I have performed loopback test to my serial interfaces and they seem to be Ok.
This problem happens specially when I am not at the office.
Does anybody has a link to a document that explains all those counters?
Help.

Carrier transitions are the main clue that it is a line problem.

Can you provide a show controllers for the interface as well as the show interface serial. Since it is an intermittant problem can you provide the configuration for the Service-Module and the interface. Possibly you and the carrier are not the same on some timing parameters. These results can help us determine what and where your problem lies....

Hi,
Thanks for all your help. In fact those counters show issues with your ISP. I called them and they confirmed they had issues.
Thanks again.
