Working principle and work flow:
Receive Direction
The interface module accesses the signals sent from the external Ethernet equipment such as a LAN switch or a router, decodes the signals, converts the signals into parallel signals, and sends the parallel signals to the service processing module. The service processing module performs frame delimitation, preamble stripping, CRC code termination, and Ethernet performance counting for the parallel signals. The service processing module also classifies the traffic for the parallel signals according to the service type and configuration requirements. Then, the service processing module sends the signals to the mapping module for VC-12 or VC-3 mapping. Finally, the mapping module sends the signals to the cross-connect unit.
Transmit Direction
The mapping module demaps the VC-12 or VC-3 signals from the cross-connect unit and sends the signals to the encapsulation module. The encapsulation module encapsulates the signals and sends the signals to the service processing module. The service processing module determines the route according to the level of the equipment, classifies the traffic according to the service type and configuration requirements, performs frame delimitation, preamble adding, CRC code calculation, and Ethernet performance counting, and sends the signals to the interface module. The interface module converts the signals into serial signals, encodes the signals, and sends the signals through an Ethernet port.
