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.
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 refernces.
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.
Frequency Mode
In Frequency mode, the system will track the frequency of the input reference. Any
phase or time information from a time reference will not be used in Frequency
mode.
Note: The command "set ref mode time" has the same
meaning as "set tod-source GPS" and "set ref mode
frequency" has the same meaning as "set tod-source sys".
