connection schemes for using telephony devices with the EMTA.
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 EMTA.
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 EMTA. 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 EMTA. (Other phones can be added to each line
by using standard phone line splitters.

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 EMTA 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. Can I watch TV, surf the Internet, and talk to my friends through the EMTA 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
Cable Modem will work with all upgraded cable systems that are DOCSIS-compliant.
Q. What is PacketCable and what does it mean?
A. Like DOCSIS, Euro-PacketCable/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 EMTA will work with all upgraded cable systems that are PacketCable-compliant.

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
Check all of the connections to your EMTA.
z
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 EMTA 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 EMTA 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 (Online light not on continuously).
z
If the modem is in Initialization Mode, the INTERNET lights 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 24 for details.)
z
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.
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
32
Chapter 3: Additional Information
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 DOCSIS-compliant and PacketCable-compliant
by calling your cable provider.
I don’t hear a dial tone when I use a telephone.
z
Telephone service is not activated. If the rightmost light on the EMTA stays on while
others flash, check with your TSP or cable company.
z
If the EMTA 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.
