OSN3500 Site A OptiX OSN 3500 devices with UXCSB cross boards with expansion subracks. the site's clock signal references an external clock source signal and forms an MSP ring with other OptiX OSN 3500 devices. the other site clocks track the source of this site's clock.
OSN3500 External Source Output Thresholds
Parameter Meaning
External Source Output Threshold - Sets the external source output quality threshold to control the external source output using the 2M phase-locked source failure action when the clock quality level of the external source output is lower than the external source threshold.
Impact on System
Does not affect system operation.
Parameter Value
|
Value range |
Default value |
|---|---|
|
Threshold not activated, not inferior to G.813 SETS signal, not inferior to G.812 local office clock signal, not inferior to G.812 transfer office clock signal, not inferior to G.811 clock signal |
Threshold not activated |
The meaning of each parameter value is as follows.

Description |
|---|---|
|
Threshold not activated |
External source output quality threshold not activated |
|
Not inferior to G.813 SETS signal |
The external source will be disabled if the external source output quality is less than G.813 signaling |
|
Not inferior to G.812 local station clock signal |
External source will fail if the external source output quality is less than the G.812 local office clock signal |
|
Not inferior to G.812 transfer office clock signal |
External source will fail if the output quality of the external source is less than the G.812 transfer office clock signal |
|
Not inferior to G.811 clock signals |
If the output quality of the external source is less than the G.811 signal, the external source will be invalidated. |
Principle of value
The external source output clock quality should not be inferior to the value set by the quality threshold, so the set quality threshold should be less than or equal to the clock quality level output by the network element.
Correlation with other parameters
This parameter is valid only when the "Protection Status" is set to "Enable Standard SSM Protocol".
