Table 2 Comparison of the access capability of SEP1 board with different outlet boards and electrical interface reversing boards

SEP1 board accomplishes STM-1 signal processing. When SEP1 adopts panel outlet (the logic single board of the network management display is SEP1), it completes the processing of 2-channel STM-1 electrical signals; when SEP1 board cooperates with wiring board (the logic single board of the network management display is SEP), it completes the processing of 8-channel STM-1 optical/electrical signals, or 4-channel STM-1 electrical signals. The physical single board of both is SEP1, collectively referred to as SEP1 when no distinction is made between logical single boards.
