When the received optical power level (in dBm) is lower than
the power low threshold setting, the Power Low alarm will
occur. (MPM-10G card only)
The threshold value is entered using an on-screen keypad,
and can range from -10.0 dBm to -100.0 dBm in increments
of 0.1 dBm. The default value is -100.0 (Disabled).
For the MPM-100G and MPM-100AR cards, the
Low Threshold setting is supported on the MLD tab.
Sets the threshold for which the Frequency Wide alarm
occurs. When the received Line Frequency Offset (in ppm)
exceeds the set threshold setting, the Frequency Wide alarm

The threshold value is entered using an on-screen keypad,
and can range from 0 ppm to +/- 300.0 ppm in increments of
0.1 ppm. The default value is 0 ppm (Disabled).
