I've got a point-to-point T-1 from my headquarters to another location about 10 miles away. The line coding is set to ami (not sure why, it's only been out there for about a year)... But on the HQ side of the circuit, I show the red alarm on the smartjack, on the remote side, no alarm and the circuit stays up, but I'm sure I am showing alarm for some reason... I would think this would cause some performance issues or at least some jitter. The guys at the telco are clueless, and tell me it's my equipment. I've changed out equipement on both sides and still have the same issue...
I've hardcoded on both routers to set the linecode to AMI with:
service-module t1 data-coding inverted
service-module t1 linecode ami
Does anyone have any ideas on what could be the issue here??
