Wall Mounting
Number of screws: 2 pieces.
Direction for wall mounting: LED panel upward.
Dimension for the screw: 4.4 mm.
There are 4 slots on the underside of the gateway 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.
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.

elationship among the Devices
This illustration shows a cable company that offers Euro-DOCSIS- and Euro-PacketCable-compliant
voice/data services.
What the Modem Does
The Wireless 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
Euro-PacketCable compliant headend equipment and provide the IP-based voice communications. The
IP traffic can transfer between the Wireless Voice Gateway and Euro-DOCSIS compliant headend
equipment. The data security secures upstream and downstream communications.
What the Modem Needs to Do Its Job
The ight Cable Company: Make sure your local cable company provides data services that
use cable TV industry-standard Euro-DOCSIS compliant and Euro-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
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
•SSID, WPA2-PSK information
Please verify the following with the cable company
The cable service to your home supports Euro-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 Wireless Voice Gateway to a Single Computer
This section of the manual explains how to connect your Wireless 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 Wireless 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 Wireless Voice Gateway to the first
point the cable enters your home. The splitter
must be rated for at least 1GHz.

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 Wireless Voice Gateway CD included with your modem
contains the drivers and other information you need to install your Wireless Voice Gateway.
USB Connection
If you do not want to use the CD-ROM, follow instructions 1 through 5 to connect the Wireless 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 Wireless Voice Gateway.
2. Connect the plug from the AC power supply into the POWER AC ADAPTER jack on the Wireless
Voice Gateway and plug the power supply into an AC outlet.
3. Insert the supplied Wireless Voice Gateway CD-ROM. Wait momentarily for the CD window display.
Fig. 3
4. Close all open applications and dialog boxes, including the CD window.
Note: Some applications may interfere with your Wireless 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 Wireless 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 XP for USB Connection
Follow steps 6 through 9 if you have a Windows XP operating system:
6. Windows XP will display the “Welcome to the Found New Hardware Wizard” window, and ask
whether you would like the Windows to connect to Windows Update to search for software, Choose
“No, not this time” and click “Next”.
Fig. 4
7. The “Found New Hardware Wizard” will then display the device name and ask you to insert the
installation CD-ROM that came with the unit. Choose the “Install from a list or specific location
(Advanced)” option, and click “Next.”
Fig. 5
Note: If Windows XP does not recognize the presence of the Wireless Voice Gateway, i.e., the “Welcome
to the New Hardware Wizard” did not automatically appear, your BIOS settings may not permit USB
and/or Plug-and-Play devices. Please contact the customer service department of the computer
company.
