A table that contains a history of the
cgspLinkUtilizationRcvd and cgspLinkUtilizationRcvd
objects. In order to properly manage network capacity
it is necessary to collect utilization information during
short interval. These intervals are less than 5 minutes and
can be as low as 1 minute. The number of links supported by
a signalling point prevent polling each signalling point
to collect information. This table is provided to allow an
NMS to collect the information during a normal poll cycle.
