Working Principle and Signal Flow

The EFS8 board consists of the interface module, service processing module, mapping/demapping module, interface conversion module, communications and control module, and power module.

Figure 1 considers a channel of FE signals as an example to show the working principle of the EFS8 board.

Figure 1 Principle block diagram of the EFS8 board

In the Transmit Direction

The cross-connect unit transmits signals to the encapsulation and mapping module through the interface conversion module for demapping and decapsulation. The service processing module determines the service routes according to the equipment level, and classifies the flow according to the service type and configuration requirements. Then, the service processing module performs frame delimitation, preamble adding, CRC code computing, and Ethernet performance count. Finally, the interface conversion module converts the parallel signals to series signals, and transmits the series signals through an Ethernet interface.

In the Receive Direction

After accessing the Ethernet signals from external Ethernet equipment (for example, an Ethernet switch and a router), the Ethernet interface module decodes the signals, and then coverts serial signals to parallel signals. Then, the service processing module aligns the frames, strips the preamble code, terminates the cyclic redundancy check (CRC) code and performs the statistics for the Ethernet performance. The service processing module also classifies the flow according to service type and configuration requirement. The packets in the IEEE 802.1q-compliant and IEEE 802.1ad-compliant formats are supported. In addition, the service processing module adds CVlan and SVlan tags for mapping and forwarding the services. Then, the encapsulation module encapsulates the Ethernet frames in the HDLC, LAPS, or GFP-F format, transmits the frames to the mapping/demapping module, which then maps the frames. Finally, the encapsulation module transmits the frames to the cross-connect unit through the interface conversion module.

Communication and Control Module

The communication and control module provides the communication, control, and service configuration functions of the board.
