A configuration command that modifies the call access control parameters of a cell. In this command, the following parameters uniquely identify the cell:
Cell Index or Cell Name
| ID | Name | Description |
|---|---|---|
| IDXTYPE | Index Type | Meaning:Index Type Value range:BYNAME(By Name),BYIDX(By Index) Explanation:Index Type. Default value:None |
| CELLIDX | Cell Index | Meaning:Cell Index Value range:0~2047 Explanation: This parameter indicates the source cell index. The source cell index must be unique. Default value:None |
| CELLNAME | Cell Name | Meaning:Cell Name Value range:1-32 characters Explanation: This parameter indicates the name of the source cell. The name of each cell under one BSC must be unique. Default value:None |
| VOICEVER | Speech Version | Meaning:Speech Version Value range:Full_rate_Ver1(1),Full_rate_Ver2(2),Full_rate_Ver3(3),Half_rate_Ver1(4),Half_rate_Ver2(5),Half_rate_Ver3(6) Explanation:This parameter specifies the speech version supported by the BSC. The value of this parameter has six bits. The six bits (from the most significant bit to the least significant bit) indicate the following speech versions respectively: half-rate version 3, half-rate version 2, half-rate version 1, full-rate version 3, full-rate version 2, and full-rate version 1. Here, versions 3, 2, and 1 indicate AMR, EFR, and FR respectively. If a bit is 1, you can infer that the BSC supports the corresponding speech version. If a bit is 0, you can infer that the BSC does not support the corresponding speech version. For example, if the parameter is set to 001011, you can infer that full-rate versions 1-2 and half-rate version 1 are supported. In the HDLC networking mode, if only full-rate version 1 among the three full-rate versions is selected, it is recommended that the AEC delay of all the DSPs in the DPUX and DPUC be set to 141 so that the downlink traffic flow is further decreased. Default value:None |
| TRXAIDSWITCH | TRX Aiding Function Control | Meaning:TRX Aiding Function Control Value range:TRXAid_NotAllow(TRX Aiding Not Allowed),AllowReForbid(Allowed & Recover Forbidden),AllowReImmed(Allowed & Recover Immediately),AllowReCheckRes(Allowed & Recover When Chk Res) Explanation:This parameter specifies the following rules for TRX aiding function control: TRX Aiding Not Allowed: The TRX aiding function is disabled. Allowed & Recover Forbidden: The TRX aiding is allowed but the switchback is forbidden after the faulty TRX is restored. Allowed & Recover Immediately: The TRX aiding is enabled but the switchback is performed immediately after the faulty TRX is restored. Allowed & Recover When Check Res: The TRX aiding is enabled and the switchback is not immediately performed after the faulty TRX is restored. Instead, the switchback is performed during the resource check in the early morning, usually 2 o'clock. Default value:None |
| RANERRTHRED | Random Access Error Threshold | Meaning:Random Access Error Threshold Value range:0~255 Explanation:This parameter specifies the correlation between training sequences. According the GSM protocols, the system determines whether the received signal is the random access signal of an MS through the correlation between training sequences (41 bits) and calculates the TA value. Default value:None |
| PWRDIVIND | Power Deviation Indication | Meaning:Power Deviation Indication Value range:NO(NO),YES(YES) Explanation:The MS does not receive the original power command after random access. This parameter indicates whether the power deviation is added to the class 3 MS on the DCS1800 band on the basis of the maximum MS transmit power. Default value:None |
| PWRDIV | Power Deviation[2dB] | Meaning:Power Deviation[2dB] Value range:0~3 Explanation:When Power Deviation Indication is set to Yes, the transmit power of an MS is the MS maximum transmit power level plus the power calculated from the power deviation if the class 3 MS on the DCS1800 band does not receive the original power command after random access. For details, see GSM Rec. 05.08. Default value:None |
