upstream direction (from CPE to base). Similarly, the base can be configured to limit the amount of
data transmitted in the downstream direction (from base to CPE) on CPE by CPE basis.
Using SPEEDView, the graphic above illustrates a point-to-multipoint network topology. The

"beads" are used to indicate how much bandwidth is being used at a given point in time. The higher
