l 4.4.4 Data Configuration Management
l 4.4.5 Security Management
l 4.4.6 Performance Management
l 4.4.7 Alarm Management
l 4.4.8 Loading Management
l 4.4.9 Upgrade Management
l 4.4.10 BTS Loading Management
l 4.4.11 BTS Upgrade Management
Hardware Involved
The OM subsystem consists of the OMUa board, OMUb board, or GBAM.
OMUa = Operation and Maintenance Unit REV:a
Power Supply Principle
The power supply subsystem of the BSC6900 adopts the dual-circuit design and point-by-point monitoring solution. It consists of the power input part and the power distribution part.
The power supply subsystem of the BSC6900 consists of the -48 V DC power system, DC power distribution frame (PDF), and DC power distribution box (PDB) at the top of the cabinet.
If a site has heavy traffic or more than two switching systems, two or more independent power supply systems should be provided. In the case of a communication center, independent power supply systems should be configured on different floors to supply power to different equipment rooms.
