				Mode		Mode		Mode

INPFRQ	The specified input port’s	T1	NSA	MN		MN		MN
	calculated received frequency
	exceeds the pull-in range of the
	LO. This alarm disqualifies an
	input as a system reference.
	Once set, this alarm clears
	when the input frequency is
	within the defined pull-in range
	limits.

INP	The specified input port has an	T1	NSA	MN		MN		MN
PHASE	excessive phase measurement
	that disqualifies it from being
	used.

EXDSC	The specified input has had	T1	NSA	MN		MN		MN
	excessive discontinuities,
	indicated by more than 3 signal
	faults of the same type within a
	5-minute window. The alarm
	clears when the window
	contains less than 3 alarms of
	the same type.

FFOFF	The specified input port has	T1	NSA	MN		MN		MN
	exceeded the Fractional
	Frequency Offset threshold.

MTIE	The specified input port has	T1	NSA	MN		MN		MN
	exceeded at least 1 of the MTIE
	alarm thresholds.

	AID = INP1 or INP2

INPDISQ	The specified input port has	T1	NSA	MN		MN		MN
	been disqualified as a possible
	system reference. The fault
	condition must be continuously
	present for the FLTDELAY
	period before disqualifying the
	input as a possible reference.
	Once set, this alarm clears
	when the input is fault-free for
	the CLRDELAY period.
