performance, construction, labeling, and information when used as
outlined below:
CAUTION
Potential equipment damage
Potential loss of service
Connecting the Telephony Modem to existing
telephone wiring should only be performed by a
professional installer. Physical connections to the
previous telephone provider must be removed and
the wiring must be checked; there must not be any
voltages. Cancellation of telephone service is not
adequate. Failure to do so may result in loss of
service and/or permanent damage to the Telephony
Modem.
• The Telephony Modem is designed to be connected directly to a
telephone.
• Connecting the Telephony Modem to the home's existing telephone wiring should only be performed by a professional installer.
• Do not use product near water (i.e. wet basement, bathtub,

• Avoid using and/or connecting the equipment during an electrical storm, to avoid risk of electrocution.
• Do not locate the equipment within 6 feet (1.9 m) of a flame or
ignition source, to avoid damage or injury from battery explosion (i.e. heat registers, space heaters, fireplaces, etc.).
• Use only power supply and power cord included with the equipment.
• Equipment should be installed near the power outlet and should
be easily accessible.
• The shield of the coaxial cable must be connected to earth
(grounded) at the entrance to the building in accordance with
applicable national electrical installation codes. In the U.S., this
is required by NFPA 70 (National Electrical Code) Article 820. In
the European Union and in certain other countries, CATV installation equipotential bonding requirements are specified in IEC
60728-11, Cable networks for television signals, sound signals
and interactive services, Part 11: Safety. This equipment is intended to be installed in accordance with the requirements of
IEC 60728-11 for safe operation.
If the equipment is to be installed in an area serviced by an IT
power line network, as is found in many areas of Norway, special attention should be given that the installation is in accordance with IEC 60728-11, in particular Annex B and Figure B.4.
• In areas of high surge events or poor grounding situations and
areas prone to lightning strikes, additional surge protection
may be required (i.e. PF11VNT3 from American Power Conversion) on the AC, RF, Ethernet and Phone lines.
• When the Telephony Modem is connected to a local computer
through USB or Ethernet cables, the computer must be properly grounded to the building/residence AC ground network. All
plug-in cards within the computer must be properly installed
and grounded to the computer frame per the manufacturer’s
specifications.

Items You Need
If you are installing the Telephony Modem yourself, make sure you have the following items on hand before continuing:
Coax Cable
• Telephony modem package: see What’s in the Box?
the package.
• Coaxial cable (coax): as shown in the image to the left, this is a thin cable
with a connector on each end. It is the same kind of wire used to connect
to your television for cable TV. You can buy coax from any electronics retailer
and many discount stores; make sure it has connectors on both ends. There
are two types of connectors, slip-on and screw-on; the screw-on connectors
are best for use with your Telephony Modem. The coax should be long
enough to reach from your Telephony Modem to the nearest cable outlet.
• Phone Cable: as shown in the image to the left, this is a standard phone
cable with standard phone connectors (RJ11 type) on both ends. You can
buy phone cables from any electronics retailer and many discount stores.
• Splitter (optional): provides an extra cable connection by splitting a single
outlet into two. You may need a splitter if you have a TV already connected
to the cable outlet that you want to use. You can buy a splitter from any
electronics retailer and most discount stores; you may also need a short
piece of coax cable (with connectors); use it to connect the splitter to the
cable outlet and then connect the Telephony Modem and TV to the splitter.
Note: A splitter effectively cuts the signal in half and sends each half to its
two outputs. Using several splitters in a line may deteriorate the quality of
your television, telephone, and/or internet connection.
• Information packet: your cable company should furnish you with a packet
containing information about your service and how to set it up. Read this
information carefully and contact your cable company if you have any questions.

Ethernet or USB?
There are two ways to connect your computer (or other equipment) to the Telephony Modem. The following will help you decide which is best for you:
Ethernet
Ethernet is a standard method of connecting two or more devices into a Local Area
Network (LAN). Use the Ethernet connection if your computer has built-in Ethernet
hardware, does not use Windows, or you want to share the Telephony Modem connection with several computers.
Note: To connect two or more computers to the Ethernet port, you will need a
hub or broadband router (available at computer retailers).
The Telephony Modem package comes with a 6-foot (1.9m) Ethernet cable (the
connectors look like wide telephone connectors); you can purchase more cables if
necessary at a computer retailer. If you are connecting the Telephony Modem directly to a computer, or to an Ethernet hub or broadband router with a cross-over
switch, ask for Category 5 (CAT5) straight-through cable. If you are connecting the
Telephony Modem to an Ethernet hub or broadband router without a crossover
Ethernet Cable
switch, ask for a Category 5 crossover cable.
USB
USB (Universal Serial Bus) is meant for connecting a variety of accessories, such
as keyboards, mice, printers, and communications devices (including Telephony
Modems) to a single computer. Use the USB connection if you have only one computer, and the computer is using a Windows operating system (Windows 2000 or
later), and has no built-in Ethernet hardware. The Telephony Modem package
comes with a 5-foot (1.6m) USB cable.
Both
If you have two or more computers, you can connect one computer to the Telephony Modem’s USB port and one or more other computers to the Ethernet port. To
connect two or more computers to the Ethernet port, you will need a hub or broadband router (available at computer retailers).
USB Cable

What About Security?
Having a high-speed, always-on connection to the Internet requires a certain
amount of responsibility to other Internet users—including the need to maintain a
reasonably secure system. While no system is 100% secure, you can use the following tips to enhance your system’s security:
• Keep your operating system updated with the latest security patches. Run
the system update utility at least weekly.
• Keep your email program updated with the latest security patches. In addition, avoid opening email containing attachments, or opening files sent
through chat rooms, whenever possible.
• Install a virus checker and keep it updated.
• Avoid providing web or file-sharing services over your Telephony Modem.
Besides certain vulnerability problems, most cable companies prohibit running servers on consumer-level accounts and may suspend your account for
violating your terms of service.
• Use the cable company’s mail servers for sending email.
•Avoid using proxy
abuse by other Internet users (some are shipped open by default). Criminals can take advantage of open proxies to hide their identity when breaking
into other computers or sending spam. If you have an open proxy, your cable company may suspend your account to protect the rest of the network.
• If you connect your Telephony Modem to a wireless LAN, make sure you enable security and encryption on the wireless hub (for the same reasons that
you should run only secured proxies). Consult the documentation and technical support of the wireless equipment provider for help.

Problems and Solutions
The Telephony modem is plugged in, but the Power light is off.
Check all power connections. Is the power cord plugged in firmly at both
ends?
If you plugged the power cord into a power strip, make sure the strip is
switched on.
Avoid using an outlet controlled by a wall switch, if possible.
Check the outlet by plugging in another device (such as a lamp).
Finally, check the fuse or circuit breaker panel.
I’m not getting on the Internet.
It may take over 30 minutes to establish a connection the first time you
power up your Telephony Modem, especially when many people are online.
Always leave your Telephony Modem plugged into AC power and connected
to the cable system.
Check the front panel lights:
•The Power and Online lights should be on.
•The Link light should be either on or blinking.
•If the Power light blinks for more than 30 minutes, call your cable
company for assistance.
Check your cable connections. Connectors should be finger-tight. The coax
cable should not be pinched, kinked, or bent sharply—any of these can
cause a break or short in the cable (you may have to replace the cable). If
you have one or more splitters between the Telephony Modem and CATV
outlet, remove the splitters and connect the Telephony Modem directly to
the outlet.
Proceed to the Ethernet or USB solutions (next page) if necessary.

I don’t have dial tone when I pick up my phone, why?
In order for telephone service to be functional on the Telephony Modem,
telephone service must have been purchased from the service provider and
configured on your Telephony Modem. The following steps should help in
identifying the source of the problem.
•Is the Power LED lit?
– If not, check to make sure the Telephony Modem is plugged in and
the outlet has power.
– If the LED is lit, go to the next step.
• Is the Online LED lit?
– If not, check the coax connection at the Telephony Modem and the
wall. Ensure they are connected and tight. If they are and you do not
have dial tone, contact your service provider.
– If the Online LED is lit, go to the next step.
• Is the Telephone (Telephone 1 or Telephone 2) LED lit?
– If not, phone service has not been provisioned on that line. Contact
your service provider.
– If it is blinking, there is a phone off hook somewhere in the house.
Find that phone and hang it up.
– If it is lit, go to the next step
• Is the Phone plugged directly into the Telephony Modem?
– Make sure the phone is plugged into the port on the back of the Te-
lephony Modem labeled “Tel 1/2” (TM602G) or “Tel 1” (TM602A/B/H)
for line 1, and “Tel 2” for line 2.
– If so, try a different phone. Make sure the new phone is a working
phone.
– If a known good phone is used and you still don’t have dial tone, try
a different phone cable. If a new phone and cable do not restore dial
tone, call your service provider.
• Is the Telephony Modem plugged into a wall outlet?

– If so, unplug the RJ-11 connector at the back of the Telephony Port
and plug in a known working phone. If you now have dial tone, the
problem is with the house wiring. Contact your MSO or a qualified
wiring technician to correct the house wiring. If you still do not have
dial tone, contact your service provider.

Downstream
In an HFC network, the direction from the head-end to the subscriber.
Some older cable documentation may refer to this as the forward path.
DOCSIS
Data Over Cable System Interface Specification. The interoperability standards used for data communications equipment on an HFC network.
EMTA
Embedded Multimedia Terminal Adapter. An MTA device that is integrated
with a cable modem.
Ethernet
A standard method of connecting two or more computers into a Local Area
Network (LAN).
Euro-DOCSIS
The European version of DOCSIS.
Event
An informational message used for monitoring network status.
F-connector
The type of connector used on coax cable. There are two common types of
F-connector, slip-on and screw-on. Use coax with screw-on connectors for
connecting your Telephony Modem.
Gateway
The device, usually a router, that connects devices on a given IP subnet to
other IP subnets.
Headend
The “central office” in an HFC network. The headend houses both video and
data equipment. In larger cable networks, a “master” headend often feeds
several “remote” headends to provide distributed services.
HTTP
HyperText Transfer Protocol.

Hub
A box with several Ethernet or USB connectors. Ethernet hubs provide a
common point of contact for all connected devices; USB hubs allow you to
add peripherals without installing a USB card in your computer.
IP address
A number assigned to your computer by your cable company, used to identify your computer to other systems on the Internet.
ISDN
Integrated Services Digital Network. A digital telephony standard that provides communication speeds about twice as fast as standard dialup.
LAN
Local Area Network. A network that allows computers in a single location
(such as a building) to communicate with one another.
LED
Light Emitting Diode. A semi-conductor diode that emits light when current
is passed through it.
MAC address
A number that uniquely identifies any device connected to a network. Your
cable company uses your Telephony Modem’s MAC address to authorize
access to the Internet. The MAC address is printed on a label on the bottom
of your Telephony Modem.
Protocol
A set of rules and formats that determines the communication behavior of
network entities at a given layer.
Proxy
A device or program that stands in between a server (for example, a web
site) and a client (your browser), providing a way to relieve some of the
burden from the server. For example, your cable company may have a web
proxy that keeps copies of popular web pages; the proxy can send you
those pages instead of fetching them directly from the web site, resulting
in faster page loading and less network congestion.

A standard 4-pin modular connector, commonly used in North America for
connecting telephones.
RJ-45
A standard 6-pin modular connector, commonly used on Ethernet cable. An
RJ-45 connector looks like a wide RJ-11 (telephone) connector.
Splitter
A small box with three cable connectors: one input and two outputs. You
may need a splitter if you have a TV already connected to the cable outlet
that you want to use for your Telephony Modem. You can buy a splitter
from any electronics retailer and most discount stores.
Switched outlet
A power outlet that may be turned on and off using a wall switch. Usually
intended for lamps. Avoid plugging your computer or Telephony Modem
into a switched outlet to avoid disruptions.
TCP/IP
Transmission Control Protocol/Internet Protocol. The protocols used to
facilitate communications across one or more connected networks.
TDMA
