The most basic of topologies is the point-to-point:  point A to point B. A point-to-point switching topology is
shown in Figure 3-4. Multiserver 5000 units can operate in a point-to-point switching topology over
terrestrial, satellite, and microwave services at speeds ranging from 9.6 to 72 Kbps. Feeder muxes can be
attached to either or both ends of the network.
