But No man, all these are based on TS allocation for EDGE in Abis interface. r u sure air interface has a ts called spdch? epansion is Packet data channel. And FPDCH is the number of TS we allocate for EDGE in radio part. And BPDCH is Basic PDCH, where in allocation is only for GPRS and not EDGE. I wanna know the details of SPDCH in Abis. Any idea?
