This read-write value represents the expected long-term utilization of the channel's bandwidth by this end point, and for CESM-8T1/E1/T3/E3 cards it is fixed at 100 percent since circuit emulation channels are provisioned to continuously use their full allocated bandwidth. An administrator would generally not need to adjust this on these card types given the fixed 100 percent expectation inherent to CES traffic. This value exists mainly for PXM's routing calculations, which use expected utilization when planning capacity across shared trunks.
