In this example, PSTN users in Salt Lake City, Utah, can dial a local number and establish a private line connection in a remote location. As in the previous example (that is, a PSTN gateway using an FXO connection) Router SLC in Salt Lake City is connected directly to the PSTN through an FXO interface. Figure 4-4 shows the topology of this connection example.
