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 configured as an IEEE-1588 Grandmaster Clock (default profile). Verify that the
network settings have been configured and tested using
netconfig
. Once the network has been
configured the Sonoma will begin to transmit PTP Sync messages after it is locked.
The PTP Sync Interval is user configured. 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 configured. 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-configurable. It is set to 32 seconds.
The PTP Priority 1 is user configured in a range from 0 to 255.
The PTP Priority 2 is user configured in a range from 0 to 255.
NOTE
If using a single Grandmaster, keep the default setting of 128 for Priority 1 and Priority 2. If using two
redundant Grandmasters, then you can configure the preferred clock by setting Priority 1 to 127 and Prior-
ity 2 to 128.
The PTP Delay Mechanism is user configured to either E2E or P2P. E2E uses the delay request-re-
sponse mechanism and P2P uses the peer delay mechanism.
The PTP Domain is user configured in a range from 0 to 255.
The PTP Time Mode is user configured to either UTC or PTP. When UTC Time mode is configured
the clock transmits the UTC epoch and sets the PTP Scale to ARB. When the Time mode is PTP the
