The GPS reference uses a GPS receiver to synchronize the internal clocks. The stratum level for
this reference is 1. To use the GPS reference, the GPS option must be installed.
The Reference Stable may be either ‘TRUE’ or ‘FALSE’. It is ‘TRUE’ when the Network Time
Adapter has acquired the time from a reference. It is ‘FALSE’ when the Network Time Adapter has
yet to acquire time from a reference.

Reference Status
The Reference Status consists of three fields, the GPS, Open Satellite Status, and GPS Settings. If
the GPS reference is not selected, then GPS will display ‘Fault’. If the GPS reference is selected and
not ready, then GPS will display ‘Acquiring’. If the GPS reference is selected and ready, then GPS
will display ‘Locked’. The Open Satellite Status link is available for the GPS reference only. The
GPS Settings link is available for the GPS reference only. The following two sections describe the
two links.
