Reply To: GSM Nortel SDCCH Failed Assigment Rate

M@u,

SDCCH assignment unsuccesses are usually due to:
Congestion
Interference
Poor coverage
Hardware failures

Since the counter is counting a timer expiry, I’d go for bad coverage and faulty hardware first.
Can you check the path balance of trx 1 ? Could you try reallocating the BCCH and SDCCH to another TRX ?
