Hi all.I have a problem in regard with a international serial link.I connected the serial interfaces with DTE cables on both ends but when I enter the show int serial command on both ends I get that the interface is up but the line protocol is down.On one side of the link I also see a lot of input errors and CRCs.
When telco establishes a loop I can see both interfaces go up(line protocol says it's looped as it should) but the second they remove the loop both ends go down.The link is achieved over an unmanagable network from point A to point B with classic TDM protocol.Any advice on what could be done to rectify the problem?Is this perhaps something a telco should resolve?
site A does not receive the frames sent by the remote end
Last input 00:51:28, output 00:00:00, output hang never
while frames from A to B are flowing :
Last input 00:00:00, output 00:00:01, output hang never
Site B is not able to receive correctly
72 packets input, 3540 bytes, 0 no buffer
Received 42 broadcasts, 0 runts, 0 giants, 0 throttles
7280383 input errors, 7280380 CRC, 2757891 frame, 8 overrun, 0 ignored, 2758028 abort
so there is a problem on local loop of site B
have the telco fix the circuit, this is a common problem
hope to help
