Revertive — Indicates that for a re-validated or a newly val-
idated reference source which has a higher priority than the cur-
rently selected reference has reverted to the new reference
source.
Non-revertive — The clock cannot revert to a higher pri-
ority clock if the current clock goes offline.
(value) — The frequency offset of the currently selected
timing reference in parts per million.
ref1, ref2 — Indicates that the priority order of the timing
references.
down — The ref1 or ref2 configuration is administratively
shutdown.
up — The ref1 or ref2 configuration is administratively
enabled.
Selected — Indicates whether the first/second timing refer-
ence being used by the synchronous timing subsystem.
If it is in use, the frequency offset is indicated.
Not Selected — The first/second timing reference is not
being used by the synchronous timing subsystem.
Qualified — The timing references is qualified for use by
the synchronous timing subsystem.
Disqualified — The timing references is not qualified for
use by the synchronous timing subsystem.
Not applicable — This MDA does not use the transmit
timing subsystem.
Indicates whether the method is presently selected.
Indicates the reason why the method is not selected.
