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.

The specific functions and characteristics of the SEP1 veneer are shown in Table 1.

The SEP1 board, when used with different outgoing boards and electrical interface protection inversion boards, has different access capabilities for STM-1 signals, as shown in Table 2.

Use with single board	Function Description
None	Access and process 2-channel STM-1 electrical signals, TPS protection is not supported.
EU04	Access and process 4-channel STM-1 electrical signals.
