Quality Of Service
Quality Level (QL)
The quality of the timing signal(s) that are provided to clock a network element. The
level is provided by the Synchronization Status Marker which can accompany the timing
signal. If the System and Output Timing Quality Level mode is "Enabled", and if the
signal selected for the Station-Clock Output has a quality level below the Acceptance
Quality Level, the network element "squelches" the Station-Clock Output Signal, which

Clock) - SSU_T (Synchronization Supply Unit - Transit) - SSU_L (Synchronization
