OSHysteresis
Loss of Input Signal
Hysteresis
Integer
(0 to 1000)
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 Cisco Systems
Engineer to determine the
correct value for your
application. As a guideline,
Cisco recommends setting the
value 1 dBm above the LOS
Threshold value. With this
setting, the module will clear
the alarm if it detects a signal
level of 1 dBm above the
current LOS Threshold value.
Valid entries are between 0 and
1000 and are in dBm times 100.
For example, if the hysteresis
required is 1 dBm, the power
alarm hysteresis is 100.

Case temperature
minimum
Integer
(–10 to 10)
Read-write Notifies operations personnel
notification 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. Users should
consult with a Cisco Systems
Engineer to determine the
threshold value for their
application. As a guideline,
Cisco recommends that
minimum case temperature be
set at 1
°C. Valid entries are
between –10 and 10
°C.
