The value of tmnxOamPmCfgBgTyDirExclBinsFrAvg specifies the set of delay bins to be excluded from OAM-PM average delay calculations for the specified bin group, bin type, and direction. Configuring a set of delay bins using tmnxOamPmCfgBgTyDirExclBinsFrAvg allows outlier delay values to be excluded from average delay calculations. For example, suppose tmnxOamPmCfgBgTyDirExclBinsFrAvg has the value { bin0, bin9 } for bin group 255, bin type 'ifdv(3)', and the forward direction. Suppose the configured lower bounds for {bin group 255, bin type 'ifdv(3)'} are as follows. Bin Number Lower Bound (microseconds) 0 0 (not configurable) 1 1 2 5000 3 10000 4 15000 5 20000 6 25000 7 30000 8 35000 9 40000 Then, the average forward IFDV delay calculations for tests using bin group 255 will ignore any delay measurement that is less than 1 microsecond, or greater than or equal to 40000 microseconds. The following objects present the result of an average delay calculation: tmnxOamPmStsDelayDmmFwdAvg, tmnxOamPmStsDelayDmmBwdAvg, tmnxOamPmStsDelayDmm2wyAvg, tmnxOamPmStsDelayTwlFwdAvg, tmnxOamPmStsDelayTwlBwdAvg, and tmnxOamPmStsDelayTwl2wyAvg. Configuring tmnxOamPmCfgBgTyDirExclBinsFrAvg does not affect minimum delay or maximum delay calculations. An attempt to change tmnxOamPmCfgBgTyDirExclBinsFrAvg will be rejected if the specified bin group (i.e. tmnxOamPmCfgBinGroupId) is 1. An attempt to change tmnxOamPmCfgBgTyDirExclBinsFrAvg will be rejected if the specified bin group's administrative status (i.e. tmnxOamPmCfgBinGroupAdminStatus) is enabled.
