Clock Source Threshold - Huawei OptiX OSN 550 Configuration Manual

7 List of Parameters

7.118 Clock Source Threshold

Description
The Clock Source Threshold parameter indicates the lower quality threshold of 2M external
clock source. When the clock quality level of the external clock source that is selected from the
2M phase-locked source priority table is inferior to the threshold, the 2M phase-locked source
becomes invalid, and the action specified for 2M phase-locked source failure is invoked to
control the external clock source output.
Impact on the System
The system running is not affected.
