    check your erlang table :
    SDCCH/8 = 8 channels
    SDCCH/4 = 4 channels

    depending on the blocking rate you choose, you’ll get your answer 🙂

    Hi Praveen,
    Reason for SDCCH and TCH can be different in different network. Mainly reasons for TCH are high Timing advance, Bad quality of radio network, Bad link quality, interference, congestion and wrong mapping of PCM.

    if no congestion, it means it is a radio problem.
    therefore :
    better coverage
    better frequency planning
    declare all neighbours
    ensure cell reselect offset is not too high in your serving cell

    regards

    TA drops happen if cell is shoting more than 32 km , so the solution depends on the coverge objective .
    If you really want to cover that far like hwy site then you need to set the cell to extended range .Of course everythng comes with a price so if you turnon extended range your capacity will cut in half
    IF the cell objective is less than 32 km then you should cut the coverge by tilting or/and by reducing the power
