Optics Thresholds
Use the Optics Thresholds tab to provision alarm/alert threshold values. For a list of ONS nodes and cards that support this subtab, see Provisioning.
 
Port
Displays the port number.
LBC-LOW
Displays the minimum threshold for the laser bias current; the default (15 min/1 day) is 50 percent.
LBC-HIGH
Displays the maximum threshold for the laser bias current; the default (15 min/1 day) is 150 percent.
OPT-LOW
Displays the minimum threshold for the optical power transmitted; the default (15 min/1 day) is 80 percent.
OPT-HIGH
Displays the maximum threshold for the optical power transmitted; the default (15 min/1 day) is 120 percent.
OPR-LOW
Displays the minimum threshold for the optical power received; the default (15 min/1 day) is 50 percent.
OPR-HIGH
Displays the maximum threshold for the optical power received; the default (15 min/1 day) is 200 percent.
Set OPR
Setting the optical power received establishes the received power level as 100 percent. If the receiver power decreases, then the OPR percentage decreases to reflect the loss in receiver power. For example, if the receiver power is 6 dBm and decreases to 3 dBm, the OPR decreases by 50 percent.
Types
Select TCA or Alarm. To change the type of threshold, choose one and click Refresh.
Intervals
Select 15 Min or 1 Day for the PM interval. To change the time interval, choose the desired interval and click Refresh.
Refresh
Refreshes the tab fields.
Reset to Default
Resets the values of all thresholds to the node default threshold values.
Apply
Applies changes made to the fields in the tab.
Reset
Cancels any changes to the tab and returns the fields to their last-saved settings.
Help
Displays context-sensitive help.
