    SDCCH Drop : MS is using a SDCCH channel, and the channel is released unexpectedly.
    TCH Drop : MS is using a TCH channel, and the channel is released unexpectedly.

    SDCCH Block: MS requires a SDCCH channel but there is no more available (all busy), so the request is rejected.

    TCH block… same, but MS is asking for a TCH channel.

    Dear All,
    Good Morning,

    We have checked all the parameters related to TCH & SDCCh drop in our BSCs.

    We cannot find the reason for the drop.

    When we give the restart to our system than drop is normal for 2 to 3 days but after that problem is repeat.

    Kindly suggest if any solution is available for this isuues.
