A desired threshold for the number of Errored Seconds (ES)
within any given 1-day performance data collection interval.
If the number of ESs in a particular 1-day collection interval
reaches or exceeds this value, a gBondPmTca1DayESCrossing
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
gBondPmTca1DayESCrossing notification.
This object maps to the TR-159 attribute
aGroupPerfThreshold1DayES.
