narchai,
as a temporary workaround, put the trx pref mark to 7 on trx2 and trx3.
thanks for the indicators, those are exactly the ones I was asking for.
could you also give me the path balance (it is located in the TRX / Indicators / Radio Measurement / Path Balance / Path_balance_avg)
The problem is definitely a hardware problem… and that should translate as a poor path balance
do you know if those 2 TRX (2 & 3) are connected to the same side of the ANC ? (the ANC can be seen as “two sided” : the 2 top TRXs and the 2 bottom TRXs… each halves of the ANC is rather independant form the other)
also, i would recommend checking fi there is no feeder swap between the BTS and the Antennas, or perhaps even within the BTS. But in this case you should also see some problems in other sectors of this BTS. Unless the other sectors do not carry much traffic.
