Parameter Name |
RACH Min.Access Level(dbm) |
|---|---|
Description |
For the BTS3X in 03.0529 or later and the double-transceiver BTSs, this parameter specifies the level threshold for the random access of the MS. If the receive level of the RACH burst is smaller than the value of RACH Min.Access Level, the BTS regards this access as an invalid one and no decoding is performed. If the receive level of the RACH burst is greater than the value of RACH Min. Access Level, the BTS considers that an access request exists on this timeslot, and determines together with the value of Random Access Error Threshold whether the RACH access is valid. Generally, RACH Busy Threshold is higher than RACH Min.Access Level. Therefore, for the BTS24, RACH Min.Access Level is shielded. For the BTS2X (excluding the BTS24), the RACH Min.Access Level parameter is invalid. |
