same highest priority and quality level, the existing reference is maintained (if it belongs to this
group), otherwise an arbitrary reference from this group is selected.

QL-Disabled Mode
In QL-Disabled mode, the following parameters contribute to the selection process:
• Signal failure
• Priority
• IP Subscriber Awareness over Ethernet
• External commands
Note • If no external commands are active, the algorithm selects the reference (for clock selection) with the
highest priority that does not experience a signal fail condition. For multiple inputs having the same
highest priority, the existing reference is maintained (if it belongs to this group). Otherwise an
arbitrary reference from this group is selected.
