    Hi Ishu.
    There are 2 methods
    One
    You can enable TCH observation for that cell & can analyse the clear codes.
    Two
    You can check the raw counters of dcr_8h(TCH drop call ratio after TCH assignment)to find out which type of drop call is happening after TCH assignment,Is it tch_rf_fai or tch_abis_fail or tch_tr_fail etc ,etc……..

    Hi Ishu
    You need to enable this in the BSC for that cell.
    MML Command is “ZTPS:OBSERV:TCH_OBS:Cell_ID:;”
