156 kbit- can run full speed video over phone wire, Novell servers can act as routers. They are expensive. We do NOT want direct connects per room but do want ethernet drops per room. This requires dumb hubs per room and probably intermediate distribution hubs that are smart hubs. These are all star systems, not backbone.
Video is backbone.
Each dumb hub can take 4-16 devices with other dumb hubs considered a device. Distance from dumb hub to device cannot exceed 100 meters. Server needs network interface card and bridges needed between systems.
