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

L61
is the PTP leap 61 second indicator, either TRUE or FALSE.

PTP Operation
The RTM3205 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 RTM3205 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.
