Reply To: High SDCCH drop an low CSSR



a call is done on a TCH that belongs to a TRX that is different than the TRX with the SDCCH.

So you might have a problem on one frequency, creating high SDCCH drop, but the users that manage to access a TCH are fine, because they fall on a TRX with good quality..

you chsould check this 🙂
