Example 2 – IRIG as primary reference, NTP input as backup
In this use case, the objective is to use:
IRIG as the primary reference input
Another NTP server as backup reference
Step-by-step procedure:
1. Move the reference which has “IRIG 0” in both the Time column and “IRIG 0” in the
1PPS column to the top of the table, with a Priority value of 1. Click the Enabled
checkbox.
2.
Move the reference which has “NTP” in the Time column and “NTP” in the 1PPS
column to the second place in the table, with a Priority value of 2. Click the
Enabled checkbox.
3.
For all other references, uncheck the Enabled checkbox, so that they are all dis-
abled.
Since both of these references are
default
references, no additional references need to be
added to the Reference Priority table.
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 1 .
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 1 .
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.
