3 T_MSRFPCI expired: on the new channel no ms rf power capability indication were received in BTS (from BSC) within 20 sec fron Channel Activation. In this case probably MS was never presented on the new channel (no SABM was received in BTS);
5 handover access failure: T3105 expires ny1 times and MS never accessed on the target cell;
4 distance limit exceeded: the distance between MS and BTS exceed the maximum allowed one into the cell (attribute excessiveDistance) and so the call is released;
7 remote transcoder failure: no DL TRAU frames were received in DL direction after channel activation (for the timer TTRAU).
