    basically, both can reduce SDCCH Drop. Higher value will get better SDCCH drop. Based on my experience, RACH Threshold should be less than Rx LevAmi…

    RACH threshold is the minimum rxlev below which a RACH burst is not decoded

    RXLEV Access Min is the minimum rxlev below which a RACH burst is decoded and contains a Request for a Call (Normal or Emergency), but is rejected.

    Increasing the RLAM is usually enough to increase the SDCCH success… fyi, in alcatel, the RACH Threshold is not changeable.

    yeah, that’s why we cant set RACH Threshold > Rx Level Minimum.
