3.2 Making PSTN Calls
The following section shows you how to make and receive calls via a connection to
the PSTN. This example covers:
• The PSTN Connection - configuring the outbound line group (connection
settings) from the FXO interface card to the PSTN.
• Creating a Dialing Rule for PSTN - creating a rule which tells the X2002
when to use the PSTN connection when completing outbound calls.
• Assigning an LCR to an Authority Group - giving extensions the right to
make outbound calls via the PSTN connection.

3.2.1 The PSTN Connection
This example assumes that the X2002 has an FXO interface card already installed
(refer to the Quick Start Guide) and that you have connected your telephone
cables to the outlets that connect to your local telephone company. The front of
your X2002 should look as shown in the following figure.
In this example, the FXO interface card is installed in slot B and ports 1 - 4 are
used for the connections. You will use this information in a web configurator
screen later.
