What are the cause of Far End SEF/AIS errors on a Point to Point T1
What are the cause of Far End SEF/AIS errors on a Point to Point T1. I have a Microwave T1 connection between two facilities and have two cisco routers terminating the connections. I have a fluke t1 tester in line with the t1 and it shows these random far end errors. Is there anything to look for as far as configuration errors on the routers?
