This object is used to set a low warning threshold on
the optical parameter being monitored.
A threshold crossing condition will be indicated if the value
given by cOpticalParameterValue goes from above the value
configured in this object to below the value configured in this
object, or if the initial value of cOpticalParameterValue
object is lower than the value configured in this object. For
network elements that incorporate a soak time in the status
indications, this threshold violation will be indicated in the
cOpticalParamAlarmStatus object only after it persists for
a period of time that equals the set soak interval.
This threshold crossing may or may not be alarmed or
reported, based on the severity level specified by the
cOpticalParamLowWarningSev object.
