PSTN Gateway Access Using FXO Connection (PLAR Mode)
The following example shows how to configure Voice over IP to link users with the PSTN Gateway using an FXO connection (PLAR mode).
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, Router SLC in Salt Lake City is connected directly to the PSTN through an FXO interface.
Figure 15 illustrates the topology of this connection example.
