I found that in a document.And I have also seen that from stat that SD TS have higher BER(both in uplink and downlink) than other TS.Does BER in SD TS increased with increase in SD traffic???
I have just copied the lines from that document below:
‘SDCCH timeslots generally have higher BER than TCH, so if a carrier has high BER and the cause cannot be found, check to see if it has a very high amount of SDCCH traffic. If so, there may be nothing wrong with the carrier.’
