A desired threshold for the number of Severely Errored Seconds
(SES) within any given 1-day performance data collection
interval.
If the number of SESs in a particular 1-day collection interval
reaches or exceeds this value, a gBondPmTca1DaySESCrossing
notification MAY be generated if enabled by
gBondPortConfPmTcaEnable.
At most one notification can be sent per interval.
Setting this attribute to zero (default) effectively disables
gBondPmTca1DaySESCrossing notification.
This object maps to the TR-159 attribute
aGroupPerfThreshold1DaySES.
