    1/ that’s 3GPP specs.
    2/ 32 transcoders ?? what do you mean ?
    3/ i don’t understand

    when i started to answer, i thought i’d be able to answer more than 50%, but i understand only 33% of the questions. Let’s look at the bright side: I answered 100% of the questions that I understood 😀

    interviewers ask the weirdest questions, really.

    and there is no need to write in capital letters…

    1/ there is certainly a good reason for it… let’s see:
    a speech frame contains speech for 20ms.
    and with GSM codecs and protection, 20ms of speech are coded in 456 bits.
    so you need a net bit rate of 456 bits / 20ms..
    I’ll stop here because i don’t see how you can link that to 8TS/TRX… 🙂

    2/ there is no transcoder in the BSC. the transcoder is a dedicated equipment, outside the BSC. And one BSC is connected to one transcoder via Ater interfaces.

    Regards
    Pix
