GSCC01 SSN1GSCC01 03706410 Optical Control and Communication Board for OSN3500 System Fiber Optic Equipment

Function：It mainly completes system control, communication, and overhead processing functions.Through the LanSwitch and the fast 485 bus inter - board channel, it communicates with each single - board, realizes the management of each single - board in the sub - rack, monitors performance and alarms, and collects the status information of other functional blocks.It can also complete the fast recovery and protection switching of various services when a service failure occurs. Communication Function：It transmits OAM information to other network elements through the DCC channel, reports device alarms and performance data to the network management terminal, and responds to the commands issued by the network management terminal. Overhead Processing：Through the overhead bus sent by each service board, after time - slot switching, the FPGA processes the official - business overhead bytes to realize functions such as official - business telephones, broadcast data ports, and 64K in - phase data ports.
