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)
Operating System Windows* NT/2000/Me/XP,
Linux
Available Disk Space 125MB 50MB
Sound Card Required for audio on CD-ROM N/A
Video VGA or better (SVGA preferred) VGA or better (SVGA built-in
CD-ROM Drive Required Required
10BaseT or 100BaseT 10BaseT or 100BaseT Ethernet
An Ethernet card makes it possible for your computer to pass data to
and from the internet. You must have an Ethernet card and software
drivers installed in your computer. You will also need a standard
Ethernet cable to connect the Ethernet card to your Residential Voice
Gateway.
Mac OS** 7.6.1 or higher
preferred)
USB (Windows 2000/ME/XP only) USB Port
The Universal Serial Bus is a high speed bus that enables your
computer to communicate simultaneously with a variety of
peripherals. However, if you have other peripherals that send and
receive a lot of information, such as speakers, printers or scanners, we
recommend using an Ethernet card to support this modem.

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.

Chapter 1: Connections and Setup
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.
