Hello,I have problem with sctor A of RBS 2116,the DRU have been blocked because they don’t carry traffic.upon trouble shooting to identfy the problem the following was observed…
I swapped the y-link cable from the DXU without touching any thing of DRU the problem shifted to DRU of sector B and C.so what to conclude here because after doing this DRU of sector A operation LED light although has been blocked.
