The value of tmnxOamPmNotifThrBinLowerBound indicates the configured lower bound (in microseconds) of the MEF-35 delay bin which is the subject of the enclosing notification. When this object is part of a tmnxOamPmThrRaise notification, the notification was raised because the number of PDUs with delay greater than or equal to tmnxOamPmNotifThrBinLowerBound (in the specified measurement interval) met or exceeded the configured threshold tmnxOamPmCfgThrDelayRaise. When this object is part of a tmnxOamPmThrClear notification, the notification was raised because the number of PDUs with delay greater than or equal to tmnxOamPmNotifThrBinLowerBound (in the specified measurement interval) was less than or equal to the configured threshold tmnxOamPmCfgThrDelayClear. For example, suppose an OAM-PM delay raise threshold is configured with tmnxOamPmCfgThrDelayRaise = 1000 and tmnxOamPmCfgThrDelayLowestBin = 6. Suppose the configured lower bound (i.e. tmnxOamPmCfgBinLowerBound) for the specified bin 6 is 30,000 microseconds. Then, if the count of PDUs with delay at or above 30,000 microseconds (e.g. tmnxOamPmStsDelayDmmBin2wyCount) is 1000, and a TCA is raised, this object will report 30,000. This value must be ignored if the enclosing notification is a loss TCA (i.e. when tmnxOamPmNotifThrType is not 'delay(1)').
