I am having some problems with a MAX TNT that seems to have Lucent TAC baffled and it definitely has me tied in knots. The symptoms started Tuesday morning at 8:40am cst. For some reason the fault light on the ATM DS-3 module would start flashing for about 60 seconds and then go on solid and the card would reboot. This would occur every 2-5 minutes. The only errors that I saw were excessive fbit errors, but I would only see the errors when the fault light would start flashing. I had a T-berd hooked to the loop and would only see framing errors on the link when the fault light flashed. To isolate the problem I put a hard loop on at the ATM Switch and the port on the ATM switch stayed green. I did the same on the TNT and saw the same symptoms (fault light and rebooting). We also noticed after reconnecting this circuit that latency was very high across the link all of the time (100-400 ms). We pulled all of the cards out of the chassis with the exception of the control card, a channelized DS-3 module, and the ATM DS-3 module. Still saw the same symptoms. Replaced the ATM DS-3 module with a known good module and still saw the same symptoms. Did the same with the Channelized module with the same results... Replaced the Control Module with new software and TFTP'd configuration and got the same symptoms. Only thing left was the chassis so we replaced it and got the same symptoms. So.... With a totally new device and new software and config we were seeing the same issue. We ended up also rebuilding our Channelized DS-3 on another High Speed port off of the DCS and still got the same symptoms. We also rebuilt the ATM DS-3 link to 2 different ports on two different ATM switches and got the same symptoms. At this point the only thing that was still the same was the configuration and the software which was pretty old (7.2.3). We decided to upgrade the software to 8.0.5 and we got similiar symptoms (fault light would no longer flash... It would just go on solid and reboot). Does anyone have any ideas? I'm pretty desperate to figure this out...
