Before You Start

Please read and make sure you understand all the prerequisites for proper installation of your new Modem. Have
all the necessary information and equipment on hand before beginning the installation.

Installation Overview

The procedure to install the Modem can be described in general terms in the following steps:
1. Gather information and equipment needed to install the device. Before you begin the actual installation
make sure you have all the necessary information and equipment.
2. Install the hardware, that is, connect the cables (Ethernet and telephone) to the device and connect the
power adapter.
3. Check the IP settings on your computer and change them if necessary so the computer can access the
web-based software built into the Modem.
4. Use the web-based management software to configure the device to suit the requirements of your ADSL
account.

Requirements

To install and use the Modem you need a computer equipped with an Ethernet port (such as an Ethernet NIC)
and a web browser. You may also need to use information given to you by your ISP or ADSL service provider.
This information is stored in the Modem's memory and used to establish the ADSL connection and confirm your
identity. Read the next page for more details about these requirements.
Low Pass Filters
Since ADSL and telephone services share the same copper wiring to carry their respective signals, a filtering
mechanism may be necessary to avoid mutual interference. A low pass filter device can be installed for each
telephone that shares the line with the ADSL line. These filters are easy to install passive devices that connect to
the ADSL device and/or telephone using standard telephone cable. Ask your service provider for more
information about the use of low pass filters with your installation. Appendix B provides illustrated examples of
how to install two common styles of low pass filters.
