This object specifies the threshold of usage for all
SS7 links in SP. This object is used to determine when
to generate the cItpSpLinkRcvdUtilChange or
cItpSpLinkSentUtilChange notifications.
A value of zero indicates that no default threshold
is specified. Therefore, only links with non-zero
values for cItpSpLinkUtilThresholdRcvd or
cItpSpLinkUtilThresholdSent will generate notifications
based on link utilization.
Changes to the utilization threshold will take effect
at the end of the current interval.
