Reply To: High TCH Drop due to Bad Quality Uplink



have you tried changing the other frequencies ?
if there is interference on bcch, the you would see bad call setup, sdcch drop, sdcch assignment failure and tch drop.
if there is interference on non-bcch trx, then you’d see mostly tch drop, except if sdcch ts is also located on this trx. In which case you’d see call setup failures/sd drop/sd assign fail as well.
