Reply To: RX Diversity Alarm


To Michael:

The fault arises when one or several TRUs have
reported a signal strength imbalance of at least 12 dB during 50 minutes.

Use OMT/Maitenance/monitor/Diversity supervision meas/… check all TRUs (You should wait 5-10 min during monitoring). Select TRU with worse SSI(Side A-B), try to exchenge DTRU betwin cells, perfom monitoring again, if fault (bad SSI)goes with DTRU – install a new one, ather case – try to replase CXU. Monitor again.
