Example 3 – NTP input as the only available input (“NTP Stratum2 oper-
ation”)
In this use case, the objective is to have NTP provided by another NTP server as
the only available reference input, i.e. the unit to be configured is operated as a
Stratum 2 server. For more information, see "Configuring "NTP Stratum Syn-
chronization"" on page122.
Step-by-step procedure:
1.
Move the reference which has “NTP” in the Time column and “NTP” in the
1PPS column to the top of the table, with a Priority value of 1. Click the
Enabled checkbox.
2.
For all other references, uncheck the Enabled checkbox, so that they are all
disabled.
3. Configure the NTP Service as described under "Configuring "NTP Stratum
Synchronization"" on page122.
Note: When selecting NTP as an input reference, do not select
another reference (such as GNSS, IRIG, etc.) to work with NTP as a
reference. NTP should always be selected as both the Time and 1PPS
input when it is desired to use NTP as an input reference.
Example 4 – Time set manually by the User. Other references may or
may not be available
Note: In order for a manually set time to be considered valid and
used to synchronize SecureSync, a “User” needs to be created and
enabled in the Reference Priority table. "The "User/User" Reference"
on page210.
In this use case, the objective is to use a hand- set time, in combination with
SecureSync's oscillator as a 1PPS source as valid references.
