Access Description
Read-write Used to set the amount the input signal
must increase above the LOS Threshold
level before the alarm is cleared. This
attribute, in conjunction with the loss of
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.
Read-write Alarm notifies operations personnel if
the case temperature of the
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

Read-write Used to set the amount that the case
temperature of the module must rise
above the minimum case temperature
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.
