A configuration command that modifies the clock source type of the BTS. In this command, the following parameters uniquely identify the BTS:
BTS Index or BTS Name
1. For IP BTS, the tracing of BSC clock is not supported, and the tracing of transmission clock and IP clock are supported.
2. The parameters E1/T1 Type and E1/T1 Port No. can be configured only when the parameter Clock Type is set to IP_TRANSFER(Trace Transport Clock).
| ID | Name | Description |
|---|---|---|
| IDXTYPE | Index Type | Meaning:Index Type Value range:BYNAME(By Name),BYIDX(By Index) Explanation: Index type. Default value:None |
| BTSIDX | BTS Index | Meaning:BTS Index Value range:0~2047 Explanation: This parameter specifies the index number of a BTS. Each BTS is numbered uniquely in a BSC. Default value:None |
| BTSNAME | BTS Name | Meaning:BTS Name Value range:1-32 characters Explanation: This parameter specifies the name of a BTS. The name of each BTS is unique in a BSC. Excluding the invalid characters ';',',','"','''','=','\','%%','+++','&','#'. Default value:None |
| CLKTYPE | Clock Type | Meaning:Clock Type Value range:INT_CLK(Internal Clock),TRCBSC_CLK(Trace BSC Clock),EXTSYN_CLK(External sync. clock),IP_TIME(IP Time),IP_TRANSFER(Trace Transport Clock),TRCGPS_CLK(Trace GPS Clock),UM_CLK(Um Clock) Explanation: This parameter specifies the work mode of the BTS clock. In internal clock working mode, the BTS cannot trace the external clock. The internal clock signal of high precision is in free-run working mode. In trace BSC clock mode, the clock signals of high precision within the BTS traces the clock signals transmitted on the BSC side. In external sync. clock mode, the clock signals of high precision within the BTS traces the synchronous clock signals imported from outside. In IP clock working mode, the clock synchronization is achieved through the handshake between the IP network equipment and the IP clock server. In trace transmission clock working mode, when the BTS upgrades its transmission mode from E1 transmission to IP transmission, you can obtain the clock from the E1 cable in the transmission network given that no IP clock is available. In trace GPS clock working mode, the BTS obtains the clock from the GPS card on the DGPS board, and thus the clock synchronization is fulfilled. Default value:None |
| E1T1TYPE | E1/T1 Type | Meaning:E1/T1 Type Value range:E1(E1),T1(T1) Explanation: Transmission bearing mode of the BTS. Default value:None |
| E1T1PN | E1/T1 Port No. | Meaning:E1/T1 Port No. Value range:0~7 Explanation: E1/T1 Port No. Default value:None |
