Maintaining BTS boards involves querying the information about the BTS boards, maintaining the clock, testing the board performance, setting the board parameters, and resetting the boards.
Querying BTS Board Information
This describes how to query the information, running parameters and configuration parameters of the BTS board on the BSC6000 Local Maintenance Terminal.
Querying Board Matching Results
This describes how to query whether the actual board type matches the configured board type. You can query the board match for more than one BTS in one operation.
Querying Board Bar Code
This describes how to query the bar codes of BTS boards. You can query the bar codes of more than one BTS in one operation.
Querying the Frequency of a BTS Board
This describes how to query the frequency of a specific BTS board according to the BTS index, slot ID, and slot ID.
Querying the Status and Frequency of the Cavity Combiner
This describes how to query the status and frequencies of the cavity combiners in the DFCU/DFCB. The DFCU/DFCB has four cavities, each of which has its own status and frequency.
Modifying the Frequency of the Cavity Combiner
After the BTS is configured with a cavity combiner and runs for a short period, the frequency may be changed. You can forcedly tune the frequency of the cavity combiner.
Maintaining the BTS Clock
This describes how to query and set clock parameters, such as clock mode, trace mode, current value, and calibration value.
Switching Over a BTS Board
This describes how to manually transfer the services carried in the active board to the standby board and how to clear the alarms generated during the switchover. Only the ADMIN users, administrators, and custom users with related authorities can perform this operation.
Resetting Smoke Alarms
This describes how to clear smoke alarms for a power monitoring module manually.
Setting TMA Feeder
This describes how to set the TMA feeder, so that the DATU or the GATM can control whether to supply power to the TMA.
Setting the Bar Codes of the BTS Cabinets
The bar codes pasted on the BTS cabinets are input to the TMU board through an MML command. The BTS then reports the information to the equipment archive of the NMS to facilitate the inventory management of the devices.
Performing Loopback Test on Board Communication Links
This describes how to test the board loopback. Set the start character and step of the board data on the LMT; then, loop back the sent data; at last check the error between the received data with the sent data to learn the transmission performance of the board.
