Description: This is a bit string contained in one character representing the third nibble of the GPS fault status word. Unfortunately, SNMP numbers the bits in the reverse order, so that the enumerated values are backwards from the description contained in the User's Manual for the fault status field returned by the gpsstat command. Each bit indicates a fault when set. Currently defined fault states encoded in this value:

Bit 3: Primary Redundant Power Supply is Faulting. Bit 2: Secondary Redundant Power Supply is Faulting. Bit 1: Oscillator PLL Faulting. Bit 0: GPS Antenna or Feedline is Shorted or Open.
