This object is automatically updated in association with writes
to nbsRoadmCommonStagingApply. It indicates whether or not this
port's updated nbsRoadmCommittedTable is equivalent to a
standard ITU grid such as would come from
nbsRoadmCommonStagingQuickCfg.
If the nbsRoadmCommittedTable matches the results from a
nbsRoadmCommonStagingQuickCfg of std100Ghz(4), then this object
will report std100Ghz(4).
If the nbsRoadmCommittedTable matches the results from a
nbsRoadmCommonStagingQuickCfg of std50Ghz(5), then this object
will report std50Ghz(5).
If the nbsRoadmCommittedTable matches neither the results from a
nbsRoadmCommonStagingQuickCfg of std100Ghz(4) or std50Ghz(5),
then this object will report customized(3).
