Description: The value of tmnxOamPmCfgThrDelayExclBinFrTca specifies the bin number
of the lowest delay bin to be excluded from the OAM-PM TCA calculations
for the specified bin group, bin type, and direction.

Configuring tmnxOamPmCfgThrDelayExclBinFrTca allows outlier high delay
frames to be ignored when deciding to raise or clear a delay TCA.

For example, suppose the following values are configured for bin group
255.

Object                                                 Value
----------------------------------------------------   -----
tmnxOamPmCfgBinGroupFdBinCount.255                        10
tmnxOamPmCfgThrDelayLowestBin.255.fd(1).forward(1)         6
tmnxOamPmCfgThrDelayExclBinFrTca.255.fd(1).forward(1)      8

Then, the decision to raise or clear a Frame Delay (FD) TCA for the
forward direction will be made based on the packet counts in bins 6 and
7 (while ignoring the packet counts in bins 8 and 9).

Configuring tmnxOamPmCfgThrDelayExclBinFrTca to the value -1 specifies
that no bins are to be excluded.

Configuring tmnxOamPmCfgThrDelayExclBinFrTca does not affect the value
of delay bin packet counters (e.g. tmnxOamPmStsDelayDmmBinFwdCount).

An attempt to change tmnxOamPmCfgThrDelayExclBinFrTca to a non-default
value will be rejected if the specified bin does not exist.  Bins are
created using:
   tmnxOamPmCfgBinGroupFdBinCount,
   tmnxOamPmCfgBinGroupFdrBinCount,
   tmnxOamPmCfgBinGroupIfdvBinCount, and
   tmnxOamPmCfgBinGroupRowStatus.

An attempt to change tmnxOamPmCfgThrDelayExclBinFrTca to a non-default
value will be rejected if tmnxOamPmCfgThrDelayExclBinFrTca is less than
or equal to tmnxOamPmCfgThrDelayLowestBin.

An attempt to change tmnxOamPmCfgThrDelayExclBinFrTca will be rejected
if the specified bin group (i.e. tmnxOamPmCfgBinGroupId) is 1.

tmnxOamPmCfgThrDelayExclBinFrTca can be changed regardless of the
specified bin group's administrative status (i.e.
tmnxOamPmCfgBinGroupAdminStatus).
