PSTN Gateway Access Using an FXO Connection in PLAR Mode
The following example shows how to configure VoIP to link users with the PSTN gateway using an
Foreign Exchange Office (FXO) connection in private line, automated ringdown (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 (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.
