To set the alarm thresholds, use the SET-TH-DWDMand SET-TH-EQPTcommands (see

“SET-TH-DWDM” section on page 9-61and “SET-TH-EQPT” section on page 9-63). Alarm threshold attributes are described in Table 8-1.

Table 8-1 Alarm Threshold Attribute Definitions

	Variable		Maximum
Attribute	Definition	Syntax	Access	Description
LOSTH	Loss of signal	Integer	Read-write	Alarm notifies operations personnel if
	(input power)	(–3100 to		the optical input signal of the
	threshold	–1500)		ONS 15216 EDFA2 drops below a
				level that impacts proper operation of
				optical 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 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.
