order you assign to your available references typically is a function of their accuracy and reli
ability.
Note: The References shown on your screen may look different from the ones in
the illustration below, depending on your NetClock 9400 Series Time Server
model and hardware configuration.
Each available type of Time and 1PPS input reference is assigned a human-readable name or
“title” that is used in the Reference Priority table, indicating the type of reference. The reference
titles are listed in the following table:
Table 3-1:
Reference priority titles
