All, do you know of any issues of compatability between the NT Optera 3500 and 15454 MSPP SONET? Specifically getting LOP-P errors after building ckt through 3-node UPSR with a 3500 on 2 of the ends. The MSPP i/f is a MRC-12 OC3, and the handoff from the 3500 is an OC3. SONET test set shows path is good between MSPPs with a terminal l/b on a distant MSPP. Suspect the Optera, but if anyone has input, I'd appreciate it.
