CHAPTER 4: ADDITIONAL INFORMATION
Frequently Asked Questions
Q. What if I don’t subscribe to cable TV?
A. If cable TV is available in your area, data and voice service may be made available with or without
cable TV service. Contact your local cable company for complete information on cable services,
including high-speed internet access.
Q. How do I get the system installed?
A. Professional installation from your cable provider is strongly recommended. They will ensure proper
cable connection to the modem and your computer. However, your retailer may have offered a self
installation kit, including the necessary software to communicate with your cable ISP.
Q. Once my Wireless Voice Gateway is connected, how do I get access to the Internet?
A. Your local cable company provides your internet service*, offering a wide range of services including
email, chat, and news and information services, and a connection to the World Wide Web.
Q. It seems that the wireless network is not working
A. Check the Wireless LED on the front panel. If it is no lighted, press on the WPS button shortly, less
than 1 second, on the side of the modem, and then check again the Wireless LED. If it is lighted, then
the Wireless transmission is enabled.
Q. Can I watch TV, surf the Internet, and talk to my friends through the Wireless Voice Gateway at the
same
time?
A. Absolutely!
Q. What do you mean by “Broadband?”
A. Simply put, it means you’ll be getting information through a “bigger pipe,” with more
bandwidth, than
a standard phone line can offer. A wider, “broader” band means more information, more quickly.
Q. What is Euro-DOCSIS and what does it mean?
A. “Data over Cable Service Interface Specifications” is the industry standard that most cable comp
anies
are adopting as they upgrade their systems. Should you ever decide to move, the Wireless Voice
Gateway will work with all upgraded cable systems that are Euro-DOCSIS-compliant.
Q. What is Euro-PacketCable and what does it mean?
A. Euro-PacketCable is the industry standard for telephony services that most cable companies are
adopting as they upgrade their systems. Should you ever decide to move, the Wireless Voice Gateway
will work with all upgraded cable systems that are Euro-PacketCable compliant.
Q. What is Xpress Technology and what does it mean?
A. It is one of the popular performance-enhancing Wi-Fi technologies, designed to improve wireless
network efficiency and boost throughput. It is more efficient in mixed environments, and it can work
with 802.11a/b/g networks. When Xpress is turned on, aggregate throughput (the sum of the individual
throughput speeds of each client on the network) can improve by
up to
27% in 802.11g-only networks,
and
up to
75% in mixed networks comprised of 802.11g and 802.11b standard equipment. The

technology achieves higher throughput by re-packaging data, reducing the number of overhead control
packets, so that more useful data can be sent during a given amount of time.
* Monthly subscription fee applies.
** Additional equipment required. Contact your Cable Company and ISP for any restrictions or additional
fees.

General Troubleshooting
You can correct most problems you have with your product by consulting the troubleshooting list that
follows.
I can’t access the internet.
Check all of the connections to your Wireless Voice Gateway.
Your Ethernet card may not be working
. Check each product’s documentation for more information.
The Network Properties of your operating system may not be installed correctly or the settings may
be incorrect. Check with your ISP or cable company.
I can’t get th
e modem to establish an Ethernet connection.
Even new computers don’t always have Ethernet capabilities –
be sure to verify that your computer
has a properly installed Ethernet card and the driver software to support it.
Check to see that you are using the right type of Ethernet cable.
The modem won’t register a cable connection.
If the modem is in Initialization Mode, the INTERNET light will be flashing. Call your Cable
Company if it has not completed this 5-step process within 30 minutes, and note which step it is
getting stuck on.
The modem should work with a standard RG-
6 coaxial cable, but if you’re using a cable other than
the one your Cable Company recommends, or if the terminal connections are loose, it may not work.
Check with your Cable Company to
determine whether you’re using the correct cable.
If you subscribe to video service over cable, the cable signal may not be reaching the modem.
Confirm that good quality cable television pictures are available to the coaxial connector you are
using by conn
ecting a television to it. If your cable outlet is “dead”, call your Cable Company.
Verify that the Cable Modem service is Euro-DOCSIS compliant and PacketCable compliant by
calling your cable provider.
I don’t hear a dial tone when I use a telephone.
Telephone service is not activated. If the rightmost light on the Wireless Voice Gateway stays on
while others flash, check with your TSP or cable company. If the Wireless Voice Gateway is
connected to existing house telephone wiring, make sure that another telephone service is not
connected. The other service can normally be disconnected at the Network Interface Device located
on the outside of the house.
If using the second line on a two-line telephone, use a 2-line to 1-line adapter cable.

Glossary
10/100/1000 BaseT
–
Unshielded, twisted pair cable with an RJ-45 connector, used with Ethernet LAN
(Local Area Network). “10
/100/1000
” indicates speed (10
/100/1000 BaseT
), “Base” refers to baseband
technology, and “T” means twisted pair cable.
Authentication -
The process of verifying the identity of an entity on a network.
DHCP (Dynamic Host Control Protocol)
–
A protocol which allows a server to dynamically assign IP
addresses to workstations on the fly.
Ethernet adapters
–
A plug-in circuit board installed in an expansion slot of a personal computer. The
Ethernet card (sometimes called a Network Interface Card , network adapter or NIC) takes parallel data
from the computer, converts it to serial data, puts it into a packet format, and sends it over the
10/100/1000 BaseT LAN cable.
DOCSIS (Data Over Cable Service Interface Specifications)
–
A project with the objective of
developing a set of necessary specifications and operations support interface specifications for Cable
Modems and associated equipment.
F Connector
–
