Application Examples
VoiceXtender modems can be used in point-to-point or hub configurations. The
following subsections show typical examples of each of these applications, and
include configuration information for the modems.
For detailed information on configuration parameters and switch settings, refer
to Chapter 3, “Installation and Setup. ”
Example 1: Point-to-Point Application
In this application, a remote telephone is connected to the main Public
Switched Telecommunications Network (PSTN) network. This allows the
remote telephone to communicate with any telephone connected to the PSTN
network. As shown in Figure 2-4, the VoiceXtender provides a point-to-point
radio voice link between the remote telephone and the PSTN network.

You will only need to configure the parameters on each modem. The following
list describes the parameters for this particular application.
❚ RF Channel: Any of the ten available channels can be used. Choose a
channel that is not being interfered with. The channel selected for master
and slave units must be the same.

❚ Transmit Output Power: Typically, the minimum necessary power is
recommended for most applications. Both units in a link need not be set to
the same power level.
