    Dear folks

    All my sources of information seem to concur on is that E1 can provide up to 2.048Mbps.

    E1 has 32 time slots if all of them are used to carry data or voice then it makes since 32 TS x 64 kbps = 2.048 Mbps

    But of course TS0 is reserved not to carry data or voice as TS0 is allocated entirely to frame alignment signal pattern, a remote alarm indication bit,,,,,etc.

    TS16 reserved for CAS/CCS signalling in a voice environment, but TS16 won't be used in a data environment

    Means we will end up 30 time slots of bandwidth for voice and 31 time slots of bandwidth for data ,,,,,,,,right ?

    (Voice environment) TS0 and TS16 not to be used means we end up with 30 time slots x 64 kbps = can only achieve 1920 kbps.

    (Data environment) TS0 not to be used means we end up with 31 time slots x 64 = can only achieve 1984 kbps.

    Any clarification ?

    Those signalling channels are still carrying bits, so they don't detract from the number of megabits the line carries. Just as any TCP data they carry has headers which aren't deducted either.

    You referring to TS0 and TS16 right? Or only TS16?

    All of it. Total bandwidth is simply measured in the number of bits per second that a link can carry irrespective of whether they all get used. It has nothing to do with megabytes of data that it can deliver with that stream when x and y are used for purposes other than data. You seem to already have all the numbers you need and it looks like you are overthinking them.
