    khalil,

    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 🙂

    regards,
