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 Synchronization"" on page104.
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 check-
box.
2.
For all other references, uncheck the Enabled checkbox, so that they are all dis-
abled.
3.
Configure the NTP Service as described under "Configuring "NTP Stratum Syn-
chronization"" on page104.
Note: When selecting NTP as an input reference, do not select another ref-
erence (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 syn-
chronize SecureSync, a “User” needs to be created and enabled in the
Reference Priority table. "The "User/User" Reference" on page188.
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.
Step-by-step procedure:
1.
If necessary (see NOTE above), create a “User.”
2.
Move the reference which has “User 0” in the Time column and “User 0” in the
1PPS column to the top of the table, with a Priority value of 1. Click the Enabled
checkbox.
