Cause why error code 38664 is returned when an SW SNCP service is configured for the TOM board on the OSN 6800

The OSN 8800 of version V100R002 or later is a synchronous system, requiring that all service boards and cross-connect boards are synchronized (with the same frequencies and aligned frame headers). Therefore, a unique reference clock signal and a unique frame header are required. To meet this requirement, each service board outputs services according to the clock signal and frame header of a clock board. Therefore, the STG board is mandatory for the OSN 8800 of version V100R002 or later. If no STG board is configured, centralized service scheduling cannot be achieved. The OSN 6800 is an asynchronous system and does not require a unique reference clock or unique frame header. Therefore, no STG board needs to be configured for the OSN 6800.

The restrictions on the NQ2 line mode are as follows: In OptiX OSN 6800, if the TN12XCS board is used, the NQ2 board supports a service capacity of 40 Gbit/s when it is installed in slot 1, 4, 11, or 14. Only optical ports IN1/OUT1 and IN2/OUT2 of the NQ2 board are available and therefore the board supports a service capacity of 20 Gbit/s when it is installed in any of the other slots. If the TN11XCS board is used, only optical ports IN1/OUT1 and IN2/OUT2 of the NQ2 board are available and therefore the board supports a service capacity of only 20 Gbit/s regardless of the slot housing the board. In OptiX OSN 8800, the NQ2 board can be installed in any slot to support 40 Gbit/s service capacity.

The transmission distances of a TOM board on OSN 6800 can be 10 km, 40 km, and 80 km. The receive optical power range is �? to �?0 dB.

To create tributary SNCP protection, you need to first set the service mode and port working mode for tributary boards. Please check whether the service mode and port working mode have been configured for the TOM board.

The TN52TOM board does not support distributed ODU1 cross-connections.
