Relationship among the Devices
This illustration shows a cable company that offers Euro-DOCSIS compliant voice/data services.
What the Modem Does
The voice over IP cable modem is a residential voice-enabled cable modem that provides voice
and high-speed data services over cable via your Telephony and Internet Service Providers (TSPs/
ISPs). It converts information that originates from the Internet or your computer into electronic
messages that can be transported over the same wires your cable company uses to transport
video signals. In addition, it converts standard telephone signals to a format that can be reliably
transported over the Internet.
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 technology (for
DOCSIS, only for frequencies between 93-861 MHz).
ꢀ
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

Telephone or Fax Connection
When properly connected, most telephony devices can be used with the cable modem just as
with conventional telephone service. To make a normal telephone call, pick up the handset, wait
for a dial tone, and then dial the desired number. For services such as call waiting, use the hook
switch (or FLASH button) to change calls. The following procedures describe some of the
possible connection schemes for using telephony devices with the cable modem.
1. Connect a standard phone line cord directly from the phone (fax machine, answering
machine, caller ID box, etc.) to one of the LINE jacks on the cable modem (see Fig. 5).
2. If there is a phone line in your home which is NOT connected to another telephone service
provider, connect a standard phone line cord from a jack on this line to one of the LINE jacks
of the cable modem. Connect a standard phone line cord directly from the phone (fax
machine, answering machine, caller ID box, etc.) to one of the other jacks in the house that
uses that line.
3. If you have a multi-line telephone, connect a standard phone line cord (not an RJ-14 type line
cord) from the phone to the LINE jacks on the cable modem. (Other phones can be added to
each line by using standard phone line splitters.

After you install the cable modem and turn it on for the first time (and each time the modem is
reconnected to the power), it goes through several steps before it can be used. Each of these
steps is represented by a different pattern of flashing lights on the front of the modem.
Note: All indicators flash once prior to the initialization sequence.
If all of the lights are flashing sequentially, it means the cable modem is automatically updating
its system software. Please wait for the lights to stop flashing. You cannot use your modem
during this time. Do not remove the power supply or reset the cable modem during this process.

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 cable modem 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. *Monthly subscription fee applies.
Q. Can I watch TV, surf the Internet, and talk to my friends through the cable modem 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 DOCSIS and what does it mean?
A. “Data over Cable Service Interface Specifications” is the industry standard that most cable
companies are adopting as they upgrade their systems. Should you ever decide to move, the
Euro-DOCSIS cable modem will work with all upgraded cable systems that are
Euro-DOCSIS-compliant or DOCSIS**-compliant. ** If the DOCSIS downstream frequencies match
the Euro-DOCSIS frequency ranges.
Q. What is Euro-DOCSIS and what does it mean?
A. Euro-DOCSIS is the modified DOCSIS standard to accommodate European cable systems,
which often use 8 MHz channel spacing cable networks.

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.
z
z
Check all of the connections to your cable modem.
Your Ethernet card or USB port may not be working. Check each product’s
documentation for more information.
z
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.
All of the lights are flashing in sequence.
z
This means the cable modem is automatically updating its system software. Please wait
for the lights to stop flashing. The updating process typically lasts less than one
minute.
z
Do not remove the power supply or reset the cable modem during this process.
I can’t get the modem to establish an Ethernet connection.
z
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.
z
Check to see that you are using the right type of Ethernet cable.
The modem won’t register a cable connection (CABLE LINK light not on
continuously).
z
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. (See page 3 for details.)
z
The modem should work with a standard RG-6 coaxial cable, but if you’re using a cable
other than 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.
z
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 connecting a television to it. If your cable outlet is “dead”,
call your cable company.

z
Verify that the cable modem service is Euro-DOCSIS or DOCSIS compliant by calling your
cable provider (DOCSIS will only work if the used frequencies are between 93-861MHz).
I don’t hear a dial tone when I use a telephone.
z
Telephone service is not activated. If the rightmost light on the cable modem stays on
while others flash, check with your TSP or cable company.
z
If the cable modem 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.
z
If using the second line on a two-line telephone, use a 2-line to 1-line adapter cable.
