Description: 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.
