MODE is the PTP time mode, either UTC or PTP.
TTL is the PTP multicast time-to-live in a range from 1 to 255.
CLASS is the PTP clock class one of SYNCHRONIZED, HOLDOVER, or UNLOCKED.
SCALE is the PTP timescale either PTP or ARB.
STATE is the PTP port state one of MASTER, PASSIVE, LISTENING or INITIALIZING.
CLKID is the PTP clock source either GPS or OSC.
UTC is the PTP utc offset in seconds from TAI.
UTCV is the PTP utc offset valid, either TRUE or FALSE.
CA is the PTP clock accuracy one of 25ns, 100ns, 250ns, 1us, 2.5us, 10us, 25us, 100us,
250us, 1ms, 2.5ms, 10ms, or Unknown.
L59 is the PTP leap 59 second indicator, either TRUE or FALSE.
L61 is the PTP leap 61 second indicator, either TRUE or FALSE.
TT is the PTP time traceable indicator, either TRUE or FALSE.
FT is the PTP frequency traceable indicator, either TRUE or FALSE.
PTP Operation
The Sonoma is congured as an IEEE-1588 Grandmaster Clock (default prole). Verify that the
network settings have been congured and tested using netconfig. Once the network has been
congured the Sonoma will begin to transmit PTP Sync messages after it is locked.
The PTP Sync Interval is user congured. 1, 2, 4, 8, 16, 32, 64, or 128 packets per second are trans-
mitted as a multicast. The packets are only transmitted when the clock is fully synchronized or in
holdover with a known clock accuracy.
The PTP Announce Interval is user congured. Packets are transmitted every 1, 2, 4, 8, or 16 seconds
as a multicast. The packets are only transmitted when the clock is fully synchronized or in holdover
with a known clock accuracy.
The Delay Request Interval is not user-congurable. It is set to 32 seconds.
The PTP Priority 1 is user congured in a range from 0 to 255.
The PTP Priority 2 is user congured in a range from 0 to 255.
