hi guys
certain cells in our network are having high rate of tch half rate allocation failure what can be the reson. we are using motorola equipment.
many thanks in advance
maybe BSC congestion ?
i’m not familiar with Motorola, but half rate is well known to overload the TSU boards (signalling boards in BSC). That’s perhaps your problem ?
hi pix thanks for your response
i find out from our customer refrence document that high allocation failur is cause by tch congestion at bts.
any way have u ever come across call mute or one way speech in your neteork what it is cause by?
