This is what they sent after my first ticket: We found this circuit was on a higher level DWDM circuit that was bouncing in and out of service until it self corrected and cleared on 7/5/2023 at 09:31:21pm EDT. The [redacted] transport team has identified a high speed circuit card failure in

At a previous $dayjob, we employed a guy that was a bona fide optical guru. He had effectively memorized the 400+ page Nortel 6500 operating guide, and some of the hardware vendors would call him for advice when their TACs couldn't figure a problem out. Allegedly, he was the person who discovered

Ask them for an RFO report. They should be able to explain the diagnostics and reason for the original flapping. It's quite possible they found a problem somewhere on the path with a DWDM multiplexor or something. That wouldn't need any card replacement on your prem. -mel

I have a wave transport vendor that suffered issues twice about ten days apart, causing my link to flap a bunch. I put in a ticket on the second set of occurrences. I was told that there was a card issue identified and would be notified when the replacement happened. Ticket closed. Three
