Provisioning the Input Reference
When operating in normal (locked) mode, the TimeProvider 2300/2700 uses an
external reference, such as GNSS, to acquire the frequency and/or TOD alignment.
Selection among multiple references inputs is based on the priority or PQL value of
each qualified input. Reference switching behavior is determined by the switching
mode. The reference mode, criteria, and switching behavior are all configured with
the
set ref command. Figure 4-7 shows the set ref command hierarchy.

The reference auto selection algorithm switches to the best reference immediately
whenever it is better than the current reference according to the priority or PQL
value among the qualified input ports.
