LOSHYST

Loss of signal

Integer

Read-write

Used to set the amount the input signal

 

 

 

(input power)

(0 to 1000)

 

must increase above the LOS

 

 

 

hysteresis

 

 

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.
