    how many timeslots available in one E1 ?
    32 TS
    how many can be used to carry traffic ?
    let’s say 26 TS available for traffic
    and let’s say you are talking about the A interface, where there is only 1 channel per TS (1 channel = 64kb/s)

    There you go:
    BHT = “unknown”
    lines = 27
    blocking % = 0.5% (0.005)

    click on “calc”
    BHT = 16.55 erlang



    IF 30 SLOT OF ONE E1 is busy for one hour, how we can calculate earl age?
    plz answer me step by step.


    hi all;
    just i need to adding my information.

    1E1 have 32 TS..2 TS decrease will be get 30TS

    now we can say we have 30 TS will be used for BTS ,
    every Trx take 2 TS from PCM + 0.5 TS for signaling to this TRX
    the summation 2.5 TS related to 1Trx in BTS

    now must do calculation how many TRX can carry for 1STM
    30/2.5= 12 Trx..
    for FR
    12*8=96 TS
    assume every 4 TRx per sector that mean 2 TS will be decrease for every sector (1BCCH+1SDCCH).
    4*8-2=30 TS from Btable 20Erli ber sector

    for three sector 60 Erl.

    for HR carry double

    Many thanks for all..
