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. |
|
|
|
|
USB Port |
USB (Windows 2000/ME/XP only) |
|
|
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 DOCSISand 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.
