SCUB Control card

Description

The SCUB board is an MA5600 control board. This board controls the system and transmits upstream services to the IP network. The SCUB board can only be installed in slots 7 and 8 of the MA5600 service shelf or slot 7 of the MA5603 shelf. Always place it in slot 7 to configure SCUB.The basic working principles of the SCUB 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 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
