Provisioning the Input Reference
Provisioning the Input Reference
When operating in normal (locked) mode, the TimeProvider 5000 uses an external
reference (such as GPS) to acquire the system’s frequency and/or TOD alignment.
Table 4-14 shows the configurable parameters for reference selection.
Setting Reference Mode
The TP 5000 can be in either Time mode or Frequency mode for reference
selection. GPS, GNSS and 1PPS+TOD references inputs are time references. The
E1 and T1 reference inputs are frequency references.
Time Mode
In Time mode with a time reference, the system will track the phase of the input and
the system time will be set from the time of the input reference. With a frequency
input reference, the system will only track the frequency of the reference.
Table 4-14. Configurable Parameters for Reference Selection
Parameter Value Range Description/Notes
