    “Please tell me what is GSM anteena and how it works, what technology they are used.”

    To be honest I don’t know what you mean… but any mobile telecom antenna is pretty much alike.. there are two types, Omni and Directional.. both uses Air Interface.

    Hai vijay&raj,

    Three types of LAPD configuring methodology used while using a single E1 in ERICSSON.

    1.LAPD Concentration.
    2.LAPD unconcentration.
    3.LAPD Multiplexing.

    In LAPD concentration 13 TRU’s can be used with a single E1.
    In LAPD unconcentration 10 TRU’s can be used.
    And in LAPD Multiplexing 15 TRU’s can be used.

    hi, vijayaraj

    1.LAPD Concentration.
    2.LAPD unconcentration.
    3.LAPD Multiplexing.

    In LAPD unconcentration 10 TRU’s can be used.
    And in LAPD Multiplexing 15 TRU’s can be used.
    ———————————
    would you like explain more about LAPD?

    1.LAPD Concentration: 13*2+(13 div 4) = 26+4 = 30 < 31(E1 TimeSlot) 2.LAPD unconcentration: 10*3 = 30 < 31(E1 TimeSlot) 3.LAPD Multiplexing: 15*2= 30 < 31(E1 TimeSlot) Am i right? In method 3, how is the LAPD signalling transfered to BSC?

    and you know, vijayaraj

    there are two kind of LAPD Multiplex, MPLEX16 and MPLEX32, what are the differences?

    Hai daniel,
    its not 15*2.It should be 15*1.75=26.25.Others for TRU signalling.
