    Hi all

    I want to know what are the causes of having a cell with SDCCH traffic only, but TCH traffic is 0 Erl, inc HO nearly 0% because TCH assign is 0%

    Thanks for any help!!!

    Cell without TCH traffic… perhaps a cell at LAC Border : only Location Update are performed automatically. But nobody is calling.

    Can you check the Mean Holding Time in the cell ?
    Call drop rate ?

    Hi thank you for response.

    TCH mean holding time nearly normal value for our subscribers behaviour: 30 s, call drop about:1 %

    my cell is not border cell and is not isolated.

    You have a HW Pb in your cell.

    Hi all thanks for your responses. I solved my problem, of corse it is a HW problem (TRX).

    strange… so the TCH were not allocated in the faulty TRX ? So you should have seen a high TCH assignment failure rate…
