The ST2 boards intended for OSN 8800 devices can be installed in OSN 6800 subracks. To use the clock function of the ST2 boards, the ST2 boards must be installed in subracks that are equipped with clock boards.

Whether an OptiX OSN 8800 subrack can function as a slave subrack of an OptiX OSN 6800 subrack
Yes, it can function as a slave subrack of an OptiX OSN 6800 subrack.

Principles for configuring the ST2 board in the OptiX OSN 8800 T64 subrack
The ST2 board is optional for an OptiX OSN 8800 T64 subrack and is configured based on service requirements. It receives, processes, and transmits two OSC signals in the east and west directions. In addition, it can process IEEE 1588v2 synchronous clock signals and transparently transmit two FE signals. The ST2 board is not recommended for the networks where the ROP board, Raman board, HBA board, or optical-layer ASON is used. In such a network, the SC1 or SC2 board is recommended.

Whether TN52SCC boards can be installed in a slave OSN 6800 subrack
Yes, they can.

Impact if the ST2 board of the OSN 8800 is inserted into an extended OSN 6800 subrack due to insufficient slot resources
Normal optical monitoring can be implemented, but the IEEE 1588v2 feature is affected. In general, no STG board is required on the OSN 6800. If the IEEE 1588v2 function is required, STG boards need to be configured on the OSN 6800.
