			Variable		Maximum
		Attribute	Definition	Syntax	Access	Description
		cerent15216Edfa	Loss of	Integer	Read-write	Used to set the amount the input signal
		LOSHysteresis	signal	(0 to 1000,		must increase above the LOS Threshold
			(input	100		level before the alarm is cleared. This
			power)	default)		attribute, in conjunction with the loss of
			hysteresis			input signal alarm threshold, enables
						efficient clearing of alarms. Set this
						attribute at a value that is appropriate for
						the application so that the alarm
						condition will clear when input is stable.
						Consult with the Cisco TAC to determine
						the correct value for your application. As
						a guideline, Cisco recommends setting
						the value 1 dB above the LOS Threshold
						value. With this setting, the module will
						clear the alarm if it detects a signal level
						of 1 dB above the current LOS Threshold
						value. Valid entries are between 0 and
						1000 and are in dB times 100. For
						example, if the hysteresis required is 1
						dB, the power alarm hysteresis is 100.
		cerent15216Edfa	Minimum	Integer	Read-write	Alarm notifies operations personnel if
		CtmpMin	case	(–10 to 10,		the case temperature of the
			temperature	–5 default)		ONS 15216 EDFA2 drops below a level
						that impacts proper operation of the
						optical network. The minimum case
						temperature should be set at a value that
						is appropriate for the intended
						application and within product
						specifications. Consult with the Cisco
						TAC to determine the correct value for
						your application. As a guideline, Cisco
						recommends that minimum case
						temperature be set at 1°C. Valid entries
						are between –10 and 10°C.
		cerent15216Edfa	Minimum	Integer	Read-write	Used to set the amount that the case
		CtmpMinHystere	case	(0 to 10,		temperature of the module must rise
		sis	temperature	1 default)		above the minimum case temperature
			hysteresis			alarm level before the alarm is cleared.
						Set the hysteresis at a value that is
						appropriate for the application so that the
						alarm condition clears when the input is
						stable. Consult with the Cisco TAC to
						determine the correct value for your
						application. As a guideline, Cisco
						recommends that the hysteresis value be
						set at 1°C. Valid entries are between 0
						and 10°C. Setting this value to 0 disables
						this option.
