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.

Displays the port number.
|
|
Displays the minimum threshold for the laser bias current; the default (15 min/1 day) is 50 percent.
|
|
Displays the maximum threshold for the laser bias current; the default (15 min/1 day) is 150 percent.
|
|
Displays the minimum threshold for the optical power transmitted; the default (15 min/1 day) is 80 percent.
|
|
Displays the maximum threshold for the optical power transmitted; the default (15 min/1 day) is 120 percent.
|
|
Displays the minimum threshold for the optical power received; the default (15 min/1 day) is 50 percent.
|
|
Displays the maximum threshold for the optical power received; the default (15 min/1 day) is 200 percent.
|
|
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.
