GSR 12008 STM-1 all link down

We have GSR 12008 router & we face problem on STM-1

All links went down on STM-1 on STM-1 Link.As per me it was some issue with Nortel SDH Eqpt's port.

Find the logs.All link down/up log is not attached all link went down at 00:20:20 & all link cam up at 00:20:25.In Between link up & down our sonet link went down at 00:20:22 .

find the log

Nov 9 00:20:22 IST: %CONTROLLER-5-UPDOWN: Controller SONET 5/0, changed

state to down

Nov 9 00:20:22 IST: %CONTROLLER-5-UPDOWN: Controller SONET 5/1, changed

state to down

Nov 9 00:20:23 IST: %CONTROLLER-5-UPDOWN: Controller SONET 5/0, changed

state to up

Nov 9 00:20:23 IST: %GRP_CHOCX-5-PATH_UPDOWN: Path STM1.AU4 5/1.1,

changed state to down

I need to check whether there was any problem on GSR SONET controller bcuz Nortel Epuipemt team sent that they strongly suspect that the outage has occured due to common SDH/SONET

frame crashing and loss on temp basis within the card in slot no 5 of GSR Router.

Please if any one can tell me why link went down
