This reports the administrator-assigned priority for this specific timing reference unit within its protection group, determining the order in which the system will prefer this unit over its siblings when multiple units in the group are simultaneously available and of acceptable quality. An admin wanting a GPS-based reference preferred over a BITS feed within the same group would configure the GPS unit's priority number lower, higher preference, than the BITS unit's. For example, a unit with priority 1 would be selected ahead of a sibling unit configured with priority 2, all else being equal.
