Symmetricom XLi IEEE 1588 manual F73 Alarm Control / Status, F72CR

SSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSS

F72<CR>

The XLi responds:

F72<SP>PLL: <CLK PLL ><SP> CLK: <CLK STATUS><SP><CLK REF:><SP> PWR1:<PWR1 STATUS><SP>

PWR2: <PWR2 STATUS><SP>OSC: <OSC STATUS> <CR><LF>

where:

F	=	ASCII character F
72	=	function number
<SP>	= ASCII space character one or more.
<CLK PLL>	= Clock Phase Loop Lock status, LOCKED or UNLOCKED
<CLK STATUS>	=	Clock Status, LOCKED or UNLOCKED to the reference source shown. The
		LOCKED state is based on the F73 Time Threshold value entered by the
		operator. F73 Time Threshold sets the threshold in ns above which Time Error
		triggers an alarm. When the oscillator's predicted worst-case time error ("F13 -
		Time Error" on page 51) exceeds F73 Time Threshold, Time Error enters a fault
		state and the CLOCK STATUS becomes UNLOCKED. Otherwise the CLOCK
		STATUS is LOCKED.
<CLK REF>	=	Clock reference source GPS PRI, GPS SEC, PTP PRI, PTP SEC, (not
		supported: IRIG A, IRIG B, NASA 36) AUX REF.
<PWR1 STATUS>	= Primary Power Supply status, OK or FAILED
<PWR2 STATUS>	=	Secondary Power Supply status, OK or FAILED
<OSC STATUS>	= Rubidium oscillator status, OK or FAILED (if installed)
<CR><LF>	=	output line terminator

For example, enter:

F72<CR>

The XLi responds:

F72 CLOCK PLL	LOCKED
CLOCK STATUS LOCKED GPS PRI
PRIMARY POWER SUPPLY	OK
SECONDARY POWER SUPPLY	OK

F73 – Alarm Control / Status

Use function F73 to do the following:

•See the state of an indicator (“Locked/Unlocked” or “OK/Fault”)

•Enable or disable the alarm for each indicator
