    every BTS are the same structure. NOKIA, Nortel, Alcatel, …

    antenna = copler = tx => radio bcf => transmission => BSC…

    For NOKIA BTS ultrasite:

    LOOK at this:
    G like GSM
    D like DCS

    copler:

    DVGA => GSM
    DVDC => DCS

    Connection BYPASS or not:
    passive card for 1 or more TRX. You lose 3db if you connected by WCGA or WCDA.
    M2HA => DCS
    M2LA => GSM
    WCDA => DCS
    WCGA => GSM

    TX:(power part)

    TSDA => DCS no EDGE
    TSDB => DCS EDGE

    TSGA => GSM no EDGE
    TSGB => GSM EDGE

    BB2xx card is intelligent part of TRX.

    BB2A => No EDGE only compatible with TSGA and TSGB
    BB2E => EDGE (first generation of BB2xx EDGE) compatible with ALL, TX A and B
    BB2F => EDGE

    Radio:

    BOIA => BCF, MMI connection with BTS manager, Hubmanager and HWmanager.

    Transmission

    FXC ET1/T1 => in/out MIC 2Mbit signal.
    RRI => flexihopper I like “integrated” same function like FIU 19″

    DEAR PRAMOD GUPTA,
    1 POWER SUPPLY- GIVE POWER TO BTS
    2.BASE BAND CARD(BB2F)-CONVERT ALOLOG TO DIGITAL SINGAL
    3.BOIA CARD– ALL THE DATA WILL STORE IN IT
    4.TRANSMISSION CARD- IT IS FOR TRANSIMMION PERPOSE EITHER IT IS RRI ,E1T1,E1 OR OTHER ELSE
    5.TRX-IT IS THE CARDS WHICH HANDLE THE DIFFRENT CALLS, RECEIVER , TRANSMITTING
    6.MULTICOPLIER(M2LA)- IT DESIDE THE CALL TO WHICH TRX MEANS GIVING PATH TO PARTICULAR TRX
    7.WCDA-IT COMBINE THE SIGNAL TO REDUCE THE POWER LOSS
    8.DVJA-IT IS THE DUPLER ,WHICH RECEIVE AND TRANSMIT THE CALLS

    DEAR GEO,

    DAC VALUE IS ACTULLY SET , BECASUE THE DATE WILL TRANSFER IN 13MHZ , THROUGH BSC OR MSC , IT IS PRE SET FROM MSC THOUGH 2M EVEN , BUT IF IT IS BREAK FROM MSC THAT CASE, IT IS SET, NO PROBLEM IF IT IS LOW OR HIGH , SET FROM FREQUENCY COUNTER, INCEEASE THE DAC VALUE , WHEN FQEN COUN. SHOW 13 MHZ APPOX VALUE , SET IT PERMENATELY
