    Hi All,

    I would like to list TCH establishment failure reason.

    Here are some of them.

    Could you please help me on completing the list or warn me if one of the item in list is wrong.

    1- TCHs that are rejected because there are no radio resources available (TCH Congestion)
    2- Number of attempts to seize a TCH because of SDCCH congestion
    3- Number of TCH requests rejected because of lack of capacity in one of the BCSU units
    (Signaling Unit in Nokia Type BSC)
    4- Full Rate reject due to Half Rate
    5- Half Rate reject due to Full Rate
    6- Mismatch between the types of the requested channel and the A interface circuit
    7- TCH requests rejected because of exceeded load in the target cell
    8- No Resources available due to priority subscriber
    9- TCH requests for an underlay overlay HO rejected because of a lack of resources
    10- TCH requests for a direct access to a super-reuse TRX that are rejected because of a lack of resources during the call setup phase

    Thanks in advance.
