Hi we can use. ZERO command to see if any interference on trx TSs.(e.g I.lev 4).
Also we r using one report numbered 999. I don’t know whether it is custom made for us by the local Nokia vendor.
It tells us bts wise what’s the reason for drop call. Wheather it is trx failures, transcoder fails, failures at A-bis, failures at A interface….
Tk cr.
