Whether system control boards are required when NG WDM devices are used as slave subracks

1. OSN 8800 subracks are classified into T16, T32, T64, platform subracks, and universal platform subracks (UPSs).
Principles for configuring system control boards on OptiX OSN 8800 T16 subracks:
For electrical subracks, TN16XCH or TN16UXCM boards must be configured.
For optical subracks (master subrack), the TN16SCC board must be configured.
For optical subracks (slave subracks), no system control boards need to be configured.
Principles for configuring system control boards on OptiX OSN 8800 platform subracks and UPSs:
For the master subrack, system control boards must be configured.
For slave subracks, no system control boards need to be configured.
Principles for configuring system control boards on other OptiX OSN 8800 subracks:
System control boards must be configured on both the master and slave subracks.
2. OptiX OSN 9800 subracks are classified into U16, U32, U64, P18, and UPSs. CTU system control boards must be configured on the U16, U32, and U64 subracks of OptiX OSN 9800.
52SCC boards must be configured for OptiX OSN 9800 P18 subracks and UPSs.
Principles for configuring system control boards:
For the master subrack, system control boards must be configured.
For slave subracks, no system control boards need to be configured.
3. System control boards must be configured on both the master and slave subracks of OptiX OSN 6800.
