PRS Input Port Status Configuration


The Primary Reference Signal (PRS) is one of four possible inputs that are available on the TimeProvider. It can be enabled (eligible for input select), or disabled (not eligible for input select).

The status is either OK (no alarms) or ALM (active alarm(s) on outputs). When an input is in alarm mode, it will always be disqualified.

The  can be set from 1 to 9, this value determines which input is used when the active input is disqualified.

1 = PRS
2 = UNK/STU
3 = TYPE II/ST2
4 = TYPE I
5 = TYPE V/TNC
6 = TYPE III/ST3E
7 = TYPE IV/ST3
8 = G.813OPT3/SMC
9 = DUS

The priority setting determines which input is selected. A lower Priority level number indicates a higher priority and the input with the highest qualified priority is the one that is selected.

A PRS input supports three analog frame type values 2,048 kHz (2M), 1.544 MHz (1.544M), 2.048 MHz (2M), 5.00 MHz (5M), 6.312 MHz (6.312M) and  10.00 MHz (10M).

The highest alarm level can be critical, major, minor, or OK.

The port name is a user entered name to identify the port.
