Configuring "NTP Stratum Synchronization"
NTP Stratum Synchronization refers to the concept of using a different NTP Server or
Peer as your primary reference (instead of e.g., GNSS). This will make the VersaSync you
are configuring a Stratum2 server, since the other server is Stratum1.
To configure Stratum 2 (or greater) operation for VersaSync:
1.
Navigate to MANAGEMENT > NETWORK: NTP Setup:
2.
Click the GEAR icon in the NTP Services panel.
3.
The Edit NTP Services window will display. Click the Stratum1 tab.
4.
Uncheck all three options:
Enable Stratum 1 Operation
Uncheck this option. When the checkbox Prefer Stratum1 is unchecked,
the input from a different NTP Server or Peer will be used at all times.
Prefer Stratum1
Uncheck this option to prevent VersaSync's NTP service from “weighing” the
Timing System input heavier than input from other NTP servers. Thus, during
normal operation, the time provided by the external Stratum1 NTP server will
be used (unless its quality is determined to be low).
Note: If enabled, this function would give GPS additional
“weight” for NTP to select the GNSS input over other NTP
Servers.
Enable Stratum1 1PPS
Uncheck this option to prevent NTP from using the 1PPS input from the Tim-
ing System, but instead use the 1PPS signal from another NTP server. This will
ensure the time signal and the 1PPS signal to correlate, which tends to result
in better NTP performance.

2.8.9.8 NTP Servers and Peers
VersaSync can be configured to receive time from one or more available NTP Servers (Ver-
saSyncs or different models). This allows for NTP Servers on a timing network to be con-
figured as potential (fallback) input time references for VersaSync System Time
synchronization. In the event that a current reference becomes unavailable, VersaSync can
fallback to the other NTP Servers available on the network.
