ACR DPLL Statis-
tics
Frequency offset mean — The ACR frequency offset mean for the
previous 15 sets of 60-second intervals.
Frequency offset stddev — The ACR frequency offset standard
deviation for the previous 15 sets of 60-second intervals.
Phase error mean — The ACR input phase error mean and output
DCO mean for the previous 15 sets of 60-second intervals.
Phase error stddev — The ACR input phase error standard deviation
and output DCO standard deviation for the previous 15 sets of 60-
second intervals.
Algorithm State
Counts
Normal — The number of 2-second intervals the ACR algorithm was
in the normal state.
Phase-tracking — The number of 2-second intervals the ACR
algorithm was in the phase-tracking state.
Freq-tracking — The number of 2-second intervals the ACR
algorithm was in the frequency tracking state.
Holdover — The number of 2-second intervals the ACR algorithm
was in the holdover state.
Free-run — The number of 2-second intervals the ACR algorithm was
in the free-run state.
Events
ACR Calc Out of Range — The number of times the ACR algorithm
was internally reset.
Prolonged ACR failure — The number of times the ACR algorithm
was in the phase-tracking or holdover state for an extended period of
time.
Excessive Packet Loss — Increments every 2-second interval that
ACR is in the phase-tracking state and the tolerated packet loss
threshold is exceeded.
Excessive Phase Shift — Increments each time the ACR algorithm
transitions to the phase-tracking state from normal as a result of a
phase shift above the tolerated shift level.
