Whether the STG board is mandatory

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 based on the clock signal and frame header of the clock board. Therefore, the STG board is mandatory for the OSN 8800 of version V100R002 or later. Otherwise, centralized service grooming cannot be implemented. The OSN 6800 is asynchronous, having no requirement on a unique clock signal or frame header. Therefore, no clock board is required. The STG board is required only when IEEE 1588v2 needs to be enabled at the electrical layer.
