Reply To: querries regarding NOKIA BTS Comm.


Hi Patrick,

I am Hubert working for a Nokia project as BTS Engineer

I have a problem on Channel Failure Rate, on a certain timeslot specifically Timeslot 1 which has the SDCCH. Quality Engineers always ask for TRX replacement, is it really necessary, or are there BSC parameters needed to be corrected.

Also, Why is it that Timeslot 3 and 4 during TRX test on the TRX that has the MBCCH gives “invalid Channel Configuration” during the test. TRX test is done when site is on air. What is allocated for TRX 3 and 4 timeslot is it the GPRS allocation defined at the BSC?

I hope to be cleared on the queries .
