This object is used to specify the
Cell Delay Variation of the outgoing
cell stream of a shaper.
CDV is one of the parameters configured
to alter the characteristics of the
cell streams to acquire a desired
QOS objective. It is the variation
in the delay time, induced by buffering
cell scheduling, experienced by a cell
at network entry and exit points.
CDV must be between 7 and 1000 uSec.
