The analog device is connected to basic telephone services through the same ISDN line the router uses. Also, if you are outside of North America, you might need to provide an adapter cable for the type of connector that your device uses (the telephone uses an RJ-11 connector.) To connect the analog device to the router, connect the telephone cable (provided with the analog device) to the RJ-11 port (labeled with a telephone icon) on the rear panel of the router, as shown in Figure 4-3.
