Scenarios in which STG is required in the OSN 6800

2

The OSN 6800 is an asynchronous system and does not require a unique reference clock or unique frame header. Therefore, no STG board is required. The STG board is required only when IEEE 1588v2 needs to be enabled at the electrical layer.

Cause why the STG board is mandatory for the OSN 8800 but optional for 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.
