Relationship among the Devices
This illustration shows a cable company that offers DOCSIS- and PacketCable-compliant voice/data
services.
What the Modem Does
The Residential Voice Gateway provides wired and wireless high-speed Internet access as well as
cost-effective, toll-quality telephone voice and fax/modem services over residential, commercial, and
education subscribers on public and private networks via an existing CATV infrastructure. It can
inter-operate with the PacketCable compliant head end equipment and provide the IP-based voice
communications. The IP traffic can transfer between the Residential Voice Gateway and DOCSIS
compliant headend equipment. The data security secures upstream and downstream communications.
What the Modem Needs to Do Its Job
The Right Cable Company:
Make sure your local cable company provides data services that use
cable TV industry-standard DOCSIS-compliant and PacketCable-compliant technology.
The Internet/Telephony Service Provider (ISP/TSP):
Your cable company provides you access to an
Internet Service Provider (ISP) and Telephony Service Provider (TSP). The ISP is your gateway to
the Internet and provides you with a pipeline to access Internet content on the World Wide Web
(WWW). The TSP provides you with telephony access to other modems or other telephony services
over the Public Switched Telephone Network (PSTN).
Check with your cable company to make sure you have everything you need to begin; they’ll know if
Chapter 1: Connections and Setup
12

you need to install special software or re-configure your computer to make your cable internet service
work for you.
Contact Your Local Cable Company
You will need to contact your cable company to establish an Internet account before you can use your
gateway. You should have the following information ready (which you will find on the sticker on the
gateway):
The serial number
The model number
The Cable Modem (CM) Media Access Control (MAC) address
The Terminal Adapter (EMTA) MAC address
Please verify the following with the cable company
The cable service to your home supports DOCSIS compliant two-way modem access.
Your internet account has been set up. (The Media Terminal Adapter will provide data service if the
cable account is set up but no telephony service is available.)
You have a cable outlet near your PC and it is ready for Cable Modem service.
Note: It is important to supply power to the modem at all times. Keeping your modem plugged in will
keep it connected to the Internet. This means that it will always be ready whenever you need.
Important Information
Your cable company should always be consulted before installing a new cable outlet. Do not attempt any
rewiring without contacting your cable company first.

Connecting the Residential Voice Gateway to a Single Computer
This section of the manual explains how to connect your Residential Voice Gateway to the Ethernet port
on your computer and install the necessary software. Please refer to Figure 1 to help you connect your
Digital Cable Modem for the best possible connection.
Attaching the Cable TV Wire to the Residential Voice Gateway
1. Locate the Cable TV wire. You may find it one of three ways:
a. Connected directly to a TV, a Cable TV converter box, or VCR. The line will be connected to
the jack which should be labeled either IN, CABLE IN, CATV, CATV IN, etc.
b. Connected to a wall-mounted cable outlet.
c. Coming out from under a baseboard heater or other location. See Figure 1 for the wiring
example.
Notes: For optimum performance, be sure to connect your
Residential Voice Gateway to the first point the cable enters
your home. The splitter must be rated for at least 1GHz.
Fig. 1: Basic Home Wiring
Important Connection Information
The Residential Voice Gateway supports Telephone and Ethernet connections simultaneously.
Chapter 1: Connections and Setup

Illustrations contained in this document are for representation only.
Below are important points to remember before you connect the Residential Voice Gateway.
For Ethernet connections, go to page 14.
For telephone and fax connections, go to page 16.
Ethernet Connection to One Computer
Make the connections to the modem in the following sequence:
1. Connect one end of the coaxial cable to the cable connection on the wall, and the other end to the
CABLE jack on the Residential Voice Gateway.
2. Connect the plug from the AC power supply into the DC jack on the Residential Voice Gateway, and
plug the power supply into an AC outlet.
3. Note: Use only the power supply that accompanied this unit. Using other adapters may damage the
unit. Connect one end of the Ethernet cable (straight-wired, see below) to the Ethernet port on the
back of your computer, and the other end to the ETHERNET port on the Residential Voice Gateway.
Make sure that the Ethernet cable is straight-wired (not “null” or crossover-wired). However, you
will need a crossover-type cable if you are connecting the modem to a hub, or a hub within a port
switch that provides the same function.

Telephone or Fax Connection
When properly connected, most telephony devices can be used with the Residential Voice Gateway just
as with conventional telephone service. To make a normal telephone call, pick up the handset; listen for a
dial tone, then dial the desired number. For services such as call waiting, use the hook switch (or FLASH
button) to change calls. The following procedures describe some of the possible connection schemes for
using telephony devices with the Residential Voice Gateway.
1. Connect a standard phone line cord directly from the phone (fax machine, answering machine, caller
ID box, etc.) to one of the LINE jacks on the Residential Voice Gateway.
2. If there is a phone line in your home which is NOT connected to another telephone service provider,
connect a standard phone line cord from a jack on this line to one of the LINE jacks of the
Residential Voice Gateway. Connect a standard phone line cord directly from the phone (fax machine,
answering machine, caller ID box, etc.) to one of the other jacks in the house that uses that line.
3.
If you have a multi-line telephone, connect a standard phone line cord (not an RJ-14 type line cord)
from the phone to the LINE jacks on the Residential Voice Gateway. (Other phones can be added to
each line by using standard phone line splitters.
