Reply To: call drop due to expiry of T200 timer


Pix, I am also in bit doubt about T200 accomodation. Certainly T200 supervises the acknowledged transfer between MS and Network on the radio path (not on A-bis). But where is it accomodated on network side? in BSC or BTS? I see in 08.58 and came to conclusion that most likely than not that it is supervised by BTS on network side. And after T200 has expired N200 times then BTS sends ERROR INDication to BSC but it isn’t resets communication board because problem may be on MS side or radiointerface
