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

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 4 illustrates the topology of this connection example.
