    SPDCH is a radio timeslot, allocated on the Air interface. On the Abis, it’s called a nibble, or a GCH.

    FPDCH & BPDCH : I’ve never heard about this before. Where did you ?

    Cheers,

    Thanks for your support.

    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?

    David,

    We don’t have the same vocabulary 🙂 All the words you are using depends on which vendor you’re working on. Since i’m working with Alcatel-Lucent, I can’t help you, sorry.

    Abis allocation is the same : it strictly depending on your vendor…

    Hi david,

    fpdch(fixed pdch) – it is fixed for edge time slot and abis also fixed .can’t use any other cell

    spdch (semi dedicated pdch)- it is also for edge but in this abis are not dedicated .abis will use only when there will be demand.so in this u can save the abis.its just like switchable timeslot.
