The index of the eventEntry that is used when an unsuccessful poll is made after a number of successful polls. The eventEntry identified by a particular value of this index is the same as identified by the same value of the eventIndex object. If there is no corresponding entry in the eventTable, then no association exists. In particular, if this value is zero, no associated event will be generated, as zero is not a valid event index. This object may not be modified if the associated remPollStatus object is equal to valid(1).
