INPAIS	The specified input port has an	T1	NSA	MN		MN		MN
	AIS. When detected, the input
	is immediately removed as a
	possible reference. The AIS
	must be continuously present
	for the FLTDELAY period before
	disqualifying the input as a pos-
	sible reference. Once set, this
	alarm clears when the input sig-
	nal is fault-free for the CLRDE-
	LAY period.

INPLOS	The specified input port has a	T1	NSA	MN		MN		MN
	LOS. When detected, the input is
	immediately removed as a possi-
	ble reference. The LOS must be
	continuously present for the FLT-
	DELAY period before disqualify-
	ing the input as a possible
	reference. The alarm clears
	when the input signal is fault-free
	for the CLRDELAY period.

INPOOF	The specified input port has an	T1	NSA	MN		MN		MN
	OOF. When detected, the input
	is immediately removed as a
	possible reference. The OOF
	must be continuously present for
	the FLTDELAY period before dis-
	qualifying the input as a possible
	reference. The alarm clears
	when the input signal is fault-free
	for the CLRDELAY period.

INPFRQ	The specified input port’s	T1	NSA	MN		MN		NR
	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	Specified input port has an	T1	NSA	MN		MN		MN
