Computer Requirements
For the best possible performance from your Residential Voice Gateway, your personal computer
must meet the following minimum system requirements (note that the minimum requirements
may vary by cable companies):
IBM PC COMPATIBLE MACINTOSH**
CPU Pentium preferred PowerPC or higher
System RAM 16MB (32MB preferred) 24MB (32MB preferred)

Wall Mounting
The number of the screw: 2 pcs
Direction for wall mounting: LED panel upward.
Dimension for the screw: TBD
There are 4 slots on the underside of the EMTA that can be used for wall mounting.
Note: When wall mounting the unit, ensure that it is within reach of the power outlet.
You will need 2 suitable screws which screw diameter would be 4.4 mm to wall mount the Cable
Modem or the Battery Pack. Two different wall mount directions could be chosen for the Battery
Pack.
To do this:
1. Ensure that the wall you use is smooth, flat, dry and sturdy and use the 4 screw holes
which are 101.6 mm apart from each other.
2. Fix the screws into wall, leaving their heads 3 mm (0.12 inch) clear of the wall surface.
3. Remove any connections to the unit and locate it over the screw heads. When in line,
gently push the unit on to the wall and move it downwards to secure.

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 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 headend 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 Euro-DOCSIS or DOCSIS-compliant and
Euro-PacketCable or 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).

Chapter 1: Connections and Setup
Check with your cable company to make sure you have everything you need to begin; they’ll
know if 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
8
Chapter 1: Connections and Setup
Please verify the following with the cable company
The cable service to your home supports Euro-DOCSIS or 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.

Chapter 1: Connections and Setup
Connecting the Residential Voice Gateway to a Single Computer
This section of the manual explains how to connect your Residential Voice Gateway to the USB or
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.

Chapter 1: Connections and Setup
If you received an Installation/Quick Start kit with the purchase of your modem, you should use
the software provided in that kit. If not, the Residential Voice Gateway CD included with your
modem contains the drivers and other information you need to install your Residential Voice
Gateway.
12
Chapter 1: Connections and Setup
USB Connection
If you do not want to use the CD-ROM, follow instructions 1 through 5 to connect the Residential
Voice Gateway to the USB port on your computer. Instructions must be followed in the order they
appear.
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 POWER AC ADAPTER jack on the
Residential Voice Gateway and plug the power supply into an AC outlet.
3. Insert the supplied Residential Voice Gateway CD-ROM. Wait momentarily for the CD window
display.
4. Close all open applications and dialog boxes, including the CD window.
Note: Some applications may interfere with your Residential Voice Gateway installation.
5. Connect one end of the USB cable to the USB port located on the back of your computer.
Connect the other end of the USB cable to the USB port on the Residential Voice Gateway.
Note: Use only the power supply that accompanied this unit. Using other power supplies may
damage the unit.
Next, you need to install the USB driver for your operating system.
Using Windows 2000 for USB Connection
Follow steps 6 through 14 if you have a Windows 2000 operating system:

Chapter 1: Connections and Setup
6. When the “Found New Hardware Wizard” appears, click “Next” to initiate the search for drivers
for your USB device.
Note: If Windows 2000 does not recognize the presence of the Residential Voice Gateway, your
BIOS settings may not permit USB and/or Plug-and-Play devices. Please contact the customer
service department of the computer company.
7. Choose the “Search for a suitable driver for my device (recommended)” option, and click
“Next”.
14
Chapter 1: Connections and Setup
