c. Select a 15 Min or 1 Day performance monitoring interval radio button (available for TCA only),
and then click Refresh.
d. Click Refresh to view or modify the thresholds for each selection.
Step3 Click Apply.
Note See Chapter9, “Manage Alarms” for information about the Alarm Behavior tab, including alarm
profiles and alarm suppression.
Table18-8 Optics Threshold Options
Heading Description Options
Port Port number 1–16 for an STM-16 card, 1–4 for an
STM-64 card, 1-1-1 to 4-4-1 for an ASAP
port number
LBC-HIGH Laser bias current–maximum. Maximum
threshold for LBC.
Numeric percentage of the baseline value
LBC-LOW Laser bias current–minimum. Minimum
threshold for LBC.
Numeric percentage of the baseline value
OPT-HIGH Optical power transmitted–maximum.
Maximum threshold for OPT.
Numeric percentage of the baseline value
OPT-LOW Optical power transmitted–minimum.
Minimum threshold for OPT.
Numeric percentage of the baseline value
OPR-HIGH Optical power received–maximum.
Maximum threshold for OPR.
Numeric percentage of the baseline value
OPR-LOW Optical power received–minimum.
Minimum threshold for OPR.
Numeric percentage of the baseline value
Set OPR Setting the optical power received (OPR)
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
decreases 3 dBm, the OPR decreases 50
percent.
Click Set.
Types Sets the threshold values of alerts that
