The interval in which the metering information is
collected.
This object makes sense only if ccmtrCollectionType object
is stream which indicates that the metering records
are to be streamed to an external collection server.
This object is deprecated and replaced by
ccmtrCollectionRevInterval. While retrieving the value of
ccmtrCollectionInterval, the minimum value of 15 will be
returned if the value of ccmtrCollectionRevInterval is lower
than 15.
