Huawei TN52UXCM board consists of the ODUk/VC cross-connect module, packet switch module, control and communication module, and power supply module.


Module Function

ODUk/VC cross-connect module
The cross-connect module receives the data from each service board through the backplane to implement the electrical-layer grooming of ODUk (k= 0, 1, 2, 2e, 3, 4 or flex) signals or VC-4/VC-3/VC-12 signals. Then, the cross-connect module sends the signals to each service board to complete service cross-connection.

Packet switch module
The packet switch module receives packets from the packet processing boards through the backplane and sends services to the packet processing boards. In this manner, the packet switch module implements packet switching of Ethernet services.

Control and communication module
Controls operations on the board.
Controls operations on each module of the board according to CPU instructions.
Collects information about alarms, performance events, working states and voltage detection from each functional module on the board.
Communicates with the system control and communication board.
Power supply module
Converts the DC power supplied by the backplane into the power required by each module on the board.
