An OM command that starts the TRX loopback test, channel loopback test, and speech codec test.
1. The BSC must communicate properly with the BTS.
2. The target BTS must be configured, and the TRX must be in active state.
3. TRX loopback is performed to test the TRX performance and the channel transmission condition. The TRX loopback test includes the BIU loopback test and the TRX self loopback test.
4. Channel loopback is performed to test the transmission capability of the traffic channel and the speech channel. The channel loopback test includes the BIU loopback test and the TRX RF self loopback test on the traffic channel and the BTS speech loopback test and TRX speech loopback test on the speech channel.
5. Channel codec test is performed to test the speech codec mode of the speech channel. The test result is reported.
| ID | Name | Description |
|---|---|---|
| TSTMODE | Test mode | Meaning: test mode Value range: TRXLOOPBACK, CHLLOOPBACK, CHLCODEC Explanation: 1. In TRXLOOPBACK mode, TRX loopback is performed to test the performance of the TRX and the channel transmission condition. The loopback test includes the BIU loopback test and the TRX self loopback test. 2. In CHLLOOPBACK mode, channel loopback is performed to test the transmission capability of the traffic channel and the speech channel. The channel loopback test includes the BIU loopback test and the TRX RF self loopback test on the traffic channel and the BTS speech loopback test and TRX speech loopback test on the speech channel. 3. In CHLCODEC mode, channel codec test is performed to test the speech codec mode of the speech channel. Default value: None |
| IDXTYPE | Index Type | Meaning: how to specify a BTS Value range: BYNAME(By Name), BYIDX(By Index) Explanation: This parameter determines whether to specify a BTS by its name or index. Default value: None |
| BTSIDX | BTS Index | Meaning: BTS index Value range: 0-2047 Explanation: 1. This parameter specifies the number of the BTS. Each BTS is numbered uniquely in a BSC. 2. This parameter is mandatory if Index Type is set to BYIDX(By Index). Default value: None |
| BTSNAME | BTS Name | Meaning: BTS name Value range: 1-32 characters Explanation: 1. This parameter specifies the name of the BTS. Each BTS is named uniquely in a BSC. 2. This parameter is mandatory if Index Type is set to BYNAME(By Name). Default value: None |
| BTTSTTYPE | BT test type | Meaning: TRX loopback test type Value range: BIULOOP, TRXSELFTEST Explanation: 1. In BIULOOP type, the transmission condition of the timeslots of the TRX signaling channel on the DBUS is tested. 2. In TRXSELFTEST type, the running status of the TRX is tested. Default value: None |
| CHNTSTTYPE | Channel test type | Meaning: channel loopback test type Value range: TRXRFSELFLOOP, BIULOOP, BTSSPEECHLOOP, TRXSPEECHLOOP Explanation: 1. In TRXRFSELFLOOP type, the quality of the receiving channel and transmitting channel of the TRX is tested. 2. In BIULOOP type, the transmission condition of the timeslots of the TRX traffic channel on the DBUS is tested. 3. In BTSSPEECHLOOP type, the connection condition of the TRX speech channel between the Um interface and the BTS DBUS is tested. 4. In TRXSPEECHLOOP type, the connection condition of the TRX speech channel between the Um interface and the DSP is tested. 5. For BTS3001C, BTS3002C, or BTS3001CP, this parameter cannot be set to BTSSPEECHLOOP or TRXSPEECHLOOP. Default value: None |
| TRXNO | TRX No. | Meaning: TRX number Value range: 0-71 Explanation: This parameter specifies the TRX number in the BTS. Default value: None |
| CHNNO | Channel No. | Meaning: channel number Value range: 0-7 Meaning: This parameter specifies the channel number. Default value: None |
| SCHNNO | Sub channel No. | Meaning: subchannel number Value range: 0-7 Explanation: All the subchannels are selected if subchannel number is not specified. Default value: None |
| CHLSCHNNO | Sub channel No. | Meaning: subchannel number Value range: 0-7 Explanation: All the subchannels are selected if subchannel number is not specified. Default value: None |
| DURATH | Duration hour | Meaning: hours of the duration Value range: 0-12 Explanation: This parameter specifies the hours of the duration of the command. Default value: None |
| CHLDURATH | Duration hour | Meaning: hours of the duration Value range: 0-12 Explanation: This parameter specifies the hours of the duration of the command. Default value: None |
| DURATM | Duration minute | Meaning: minutes of the duration Value range: 0-59 Explanation: This parameter specifies the minutes of the duration of the command. Default value: None |
| DURATS | Duration second | Meaning: seconds of the duration Value range: 0-59 Explanation: This parameter specifies the seconds of the duration of the command. Default value: None |
| TRXDURATS | Duration second | Meaning: seconds of the duration Value range: 0-59 Explanation: This parameter specifies the seconds of the duration of the command. Default value: None |
| PWL | Power level | Meaning: power level Value range: 0-31 Explanation: This parameter specifies the power level of the TRX. A lower level indicates a greater power. Default value: None |
