OSN3500 SSN1SEP1 board completes STM-1 signal processing. When SEP1 uses panel out, it completes the processing of 2-channel STM-1 electrical signals; when the SEP1 board is coupled with a terminal block, 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, and they are collectively called SEP1 when they do not distinguish the logical single board.

When SEP1 board is used with different outgoing boards and electrical interface protection inversion boards, it has different access capabilities to STM-1 signals, as shown in Table 2.
| Use of single boards together | Function Description |
|---|---|
| None | Access and process 2-channel STM-1 electrical signals, does not support TPS protection. |
| EU04 | Access and process 4-channel STM-1 electrical signals. |
| EU08 | Accesses and processes 8 STM-1 electrical signals. |
| OU08 | Accesses and processes 8-channel STM-1 optical signals. |
| EU04+TSB4 | Accesses and processes 4-channel STM-1 electrical signals and realizes TPS protection for the SEP1 board. |
| EU08+TSB8 | Accesses and processes 8 STM-1 electrical signals and realizes TPS protection for the SEP1 board. |
| EU04+TSB8 | Accesses and processes 4 STM-1 electrical signals and realizes TPS protection for the SEP1 board. |
Description:
A SEP1 board supports access to the services of one interface board at most.2-way interface on the single board panel is not available when the SEP1 board is used with the outgoing board.
