I have an OC-3 (POS running PPP) between two POPs (an M10i at each end) getting errors, and this is the first time I've had to debug errors on a SONET link.
I am seeing BIP-B3 and REI-P incrementing in spurts on the Z end (e.g. 99 BIP-B3 and 45 REI-P, both showing 2 seconds), as well as ES-P and ES-PFE matching the seconds (2 in since I cleared the counters). No other error counters are incrementing (no section or line errors at all). I have seen some errors at the A end as well, but not as many or as often. When I get a spurt of errors, both ends will show an interface flap (at least most of the time; I'm not sure this is 100% of the time or not). Reading various docs, this means there is a problem somewhere between telco devices with the transmission from the Z end to the A end. Is that correct? I opened a telco ticket, but they pretty much blew it off. I know little about SONET so I am having trouble telling them what to check. I'd like to avoid intrusive testing if possible (since this is a major circuit for us). Part of the problem is that this circuit goes through 7 (yes 7!) different carriers, and I am not sure that the telco that owns the whole thing is looking at anything other than the loop on the Z end (the only piece they actually own).
