Read-write Alarm notifies operations personnel if the
optical input signal of the 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 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.
