Overview
The SCUB/SCUK board is a control board of the MA5600. It controls the system and transmits services upstream to the IP network.The SCUB/SCUK board can be installed in only slots 7 and 8 of the MA5600 service shelf, or slot 7 of the MA5603. Insert control board in slot 7 when the control board was configured.

Working Principles
Figure 2 Working principles of the SCUB/SCUK boardThe basic working principles of the SCUB/SCUK board are as follows:
· The control module configures the entire system, collects and reports status information (for example, receive the alarms of the boards through the high-level protocol between the service boards and the control board), and processes protocols.
· The switching module allocates the GE bus of the backplane.
· The power module supplies power to each functional module of the board.
· The clock module provides clock signals for each functional module of the board.
The services are processed as follows:
· In the upstream direction, the service data is transmitted to the service boards and then to the SCUB/SCUK board through the backplane. The switching module processes the data and then transmits the data upstream through the optical or electrical port.
· In the downstream direction, the service data is transmitted to the switching module through the optical or electrical port. After processing the data, the switching module transmits the data to the service boards through the backplane.
