I am troubleshooting some issues on an Ericsson RBS 2×06. I am gettnig a lost of sites with Timeslots blocked, multiple TS on the dTRU are blocked. I checked the transmission and the DIP’s and they look OK.
I am seeing TS Sync Faults and Loop Test Failed on the BSC.. and TRA PCU alarms on the RBS.
Any ideas as to the possible cause.
