Note: Peer-to-Peer Delay Mechanism is only applic-
able on networks equipped with Transparent
Clocks (switches/routers IEEE 1588 compatible).
Peer-to-Peer Delay Mechanism is not supported in
Unicast transmission mode.
PPS Offset: See "Advanced tab settings" on page504.

Configuration — General Steps
Ensure that SecureSync's PTP port is connected to the network (check the
Link Status in the PTP Status/Network page).
Ensure the PTP port speed is 100 Mb/s (see: PTP Status page > Advanced
tab > Port Speed).
Be sure that valid time and 1PPS references are currently selected (go to
MANAGEMENT/OTHER/Time Management).
In order to operate properly as a Master Clock, SecureSync must be syn-
chronized to a non-PTP reference. Confirm that the chosen reference transmits
the following information (as reported by the Time Properties on the PTP Status
page, under the Advanced tab):
The proper TAI or UTC time (including the current year)
The current TAI to UTC offset (required even if the reference’s time is in
TAI)
Pending leap second information at least a day in advance.
If the reference does not transmit this information, it must be provided by the
user in order for the Master Clock to function properly.
The built-in GNSS reference provides all information needed with no user inter-
vention.
