PATH: ACTUAL VALUES
STATUS
REAL TIME CLOCK SYNCHRONIZING
The RTC Sync Source actual value is the time synchronizing source the relay is using at present. Possible sources are:
Port 1 PTP Clock, Port 2 PTP Clock, Port 3 PTP Clock, IRIG-B, SNTP, and None.
The Grandmaster ID is the grandmasterIdentity code being received from the present PTP grandmaster, if any. When the
relay is not using any PTP grandmaster, this actual value is zero. The grandmasterIdentity code is specified by PTP to be
globally unique, so one can always know which clock is grandmaster in a system with multiple grandmaster-capable clocks.
Accuracy is the estimated maximum time error at present in the RTC, considering the quality information imbedded in the
received time signal, how long the relay has had to lock to the time source, and in the case of time signal interruptions, the
length of the interruption. The value 999,999,999 indicates that the magnitude of the estimated error is one second or more,
or that the error cannot be estimated.
PORT 1…3 PTP
STATE
is the present state of the port’s PTP clock. The PTP clock state is:
•
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, and
•
SYNCHRONIZED
if synchronized.
PTP-— IRIG-B DELTA
is the time difference, measured in nanoseconds, between the fractional seconds portion of the time
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. The value 999,999,999 indicates that the difference is not being measured due to one or both of the time sig-
nals being absent or disabled.
