CHAPTER 6: ACTUAL VALUES
is the present state of the port's PTP clock. The PTP clock state is:
PORT 1...3 PTP STATE
Disabled is the port's function setting is Disabled
No Signal if enabled but no signal from an active master has been found and selected
Calibrating if an active master has been selected but lock is not at present established
Synch'd (No Pdelay) if the port is synchronized, but the peer delay mechanism is non-operational
Synchronized if synchronized
is the time difference, measured in nanoseconds, between the fractional seconds portion of the time
PTP - IRIG-B DELTA
being received via PTP and that being received via IRIG-B. A positive value indicates that PTP time is fast compared to IRIG-
B time.
