MOTOROLA MVME147SC-1 Timer card

In the topology illustrated in Figure 15, an AT-8024 connects together 10/100 Mbps Ethernet hubs. This type of topology is often referred to as a collapsed backbone topology. The switch functions as the focal point of the network by acting as a bridge between the different workgroups. The switch transfers an Ethernet frame from hub to hub only when the destination end-node for the frame is on a different hub than the endnode that originated the frame. This reduces the amount of unnecessary data traffic in each workgroup, freeing up bandwidth and improving network performance.

Mixed Topology 

You can always combine topologies as well as build a larger network by connecting different switches together. If the switches are within 100 meters (328 feet) of each other, you can use the twisted pair ports. If the switches are further apart, then you will need to use fiber optic ports. Figure 16 illustrates a network of three AT-8026FC Fast Ethernet Switches.
