Table 4-1 Alarm Threshold Attribute Definitions

	Variable		Maximum
Attribute	Definition	Syntax	Access	Description
cerent15216Edfa	Configurati	True Value	Read-only	Indicates whether the current
CfgSaved	on saved			configuration has been saved. The value
	status			can be true or false. If false, the
				configuration is not saved.
cerent15216Edfa	Loss of	Integer	Read-only	Can be disregarded when operating
LpoutSetpoint	output	(0 to 1000,		amplifier in Constant Gain Temperature
	power	0 default)		Compensated mode (manufacturer
	setpoint			default) and Constant Pump Current
				mode. Setpoint object is only valid when
				amplifier is used in Constant Output
				Power and Idle modes.
cerent15216Edfa	Loss of	Integer	Read-write	Can be disregarded when operating
LpoutDeviation	output	(0 to 1000,		amplifier in manufacturer default
	power	200		Constant Gain Temperature
	deviation	default)		Compensated mode. Deviation object is
				only valid when amplifier is used in
				Constant Output Power and Idle modes.
cerent15216Edfa	Loss of	Integer	Read-write	Can be disregarded when operating
LpoutHysteresis	output	(0 to 1000,		amplifier in manufacturer default
	power	100		Constant Gain Temperature
	hysteresis	default)		Compensated mode. Hysteresis object is
				only valid when amplifier is used in
				Constant Output Power and Idle modes.
cerent15216Edfa	Loss of	Integer	Read-write	Alarm notifies operations personnel if
LOSThreshold	signal	(–3100 to		the optical input signal of the
	(input	–1500,		ONS 15216 EDFA2 drops below a level
	power)	–3000		that impacts proper operation of optical
	threshold	default)		network. Set this attribute at a value that
				is appropriate for the intended
				application so that the alarm condition is
				meaningful. Consult with the Cisco TAC
				to determine the threshold value for your
				application. As a guideline, Cisco
				recommends setting the threshold value
				at 3 dBm below the current input power
				level of the amplifier. Valid entries are
				between –3100 and –1500 in dBm times
				100. For example, if the total input power
				of the amplifier is –24 dBm and the loss
				of input power threshold required is –27
				dBm, the loss of input power alarm
				threshold is –2700.
