    I want to know about working of an MSC. How its connected with BSCs and the protocols involved. I know somethings about SS7, MTP, SCCP etc, but need detailed descripton. WHat things about the network must be known before installing the MSC. What links (m-link, b-link?) must be known? in short I really need very detailed information about MSC. Basic things I know very well. If someone could send me any documents that would be really appreciated. Especially Ericsson MSC.

    1. You need to know signalling data – MSC SP, SP of BSC, HLR and all other switches you connected with.
    2. You need to know data for sccp –
    GT of MSC, VLR, HLR.
    3. Numbering plan – MSISDN, MSRN/HON segments. And also all required numbering info of other networks (PSTN, PLMN). Dialing rules accepte in network. How to manage special service prefixes.
    4. You need get announcement files from operator and prepare them for load into MSC
