Before You Begin

Contacting Your Local Cable Service Provider

You need to set up an Internet access account with your local cable service provider
in order to use your cable modem. When you contact your cable service provider,
verify the following conditions:

• Does the cable service to your home support two-way, DOCSIS-compatible cable
modem access? If your cable service provider does not provide two-way service,
this modem will not be able to communicate with your cable service provider’s
Internet access service.

• Do you have an active RF coaxial cable connection near your PC? If your current
cable input is not conveniently located near your PC, your cable service provider
can install one.

• Do you have an Internet access account? Your cable service provider will set up
your Internet access account, and they will become your Internet Service Provider
(ISP) to enable you to send and receive e-mail, access the World Wide Web, and
receive other Internet services.

You must also give your cable service provider the following information:

• The serial number of the modem

• The Media Access Control (MAC) address of the modem

These numbers appear on a bar code label located on the cable modem. The serial
number consists of a series of alphanumeric characters preceded by S/N. The MAC
address consists of a series of alphanumeric characters preceded by MAC. The
following illustration shows a sample bar code label.

Selecting a Location for Your Modem

Select the location for your workspace and consider these recommendations:

• Position your PC and cable modem so that they are located near your cable input.
There should be plenty of room to guide the cables away from the modem without
straining or crimping them.

Before You Begin

Contacting Your Local Cable Service Provider

You need to set up a telephone account with your local cable service provider in
order to use your cable modem for telephone service. When you contact your cable
service provider, verify the following conditions:

• Does the cable service to your home supports two-way, DOCSIS-compatible cable
modem access? If your cable service provider does not provide two-way service,
this modem will not be able to communicate with your cable service provider’s
Internet access and telephone services.

• Can you transfer your existing telephone numbers from another telephony service
provider to your current cable telephony service provider? In some areas, you may
be able to transfer your existing telephone numbers, or your cable telephony
service provider will assign a new telephone number for each current or
additional active telephone line. Discuss these options with your cable telephony
service provider.

You must also give your cable service provider the following information:

• The serial number of the modem

• The Media Access Control (MAC) address of the modem

These numbers appear on a bar code label located on the cable modem. The serial
number consists of a series of alphanumeric characters preceded by S/N. The MAC
address consists of a series of alphanumeric characters preceded by MAC. The
following illustration shows a sample bar code label.

Before You Begin, Continued

Selecting a Location for Your Modem

You should work with your cable telephony service provider to choose the best
location for your cable modem. Consider these recommendations:

• Choose a location close to your computer if you will also use the cable modem for
high-speed Internet service.

• Choose a location that is near an existing RF coaxial connection to eliminate the
need for an additional RF coaxial outlet.

• Choose a location for the cable modem that is adjacent to your telephone
equipment if you are using only one or two pieces of telephone equipment.

Note: If you are using the cable modem to provide service to several telephones, a
professional installer can connect the cable modem to your existing home
telephone wiring. To minimize changes to the home telephone wiring, you may
want to locate the cable modem near an existing telephone outlet. See Install the
Cable Modem to Provide Telephone Service, later in this guide for further
instructions.

• Choose a location that is relatively protected from accidental disturbance or harm,
such as a closet, basement, or other protected area.

• Choose a location so that there is plenty of room to guide the cables away from the
modem without straining or crimping them.

• Airflow around the cable modem should not be restricted.

• Read this user’s guide thoroughly before installing the cable modem.

Telephone Requirements

Introduction

This section provides hardware and software requirements for utilizing your cable
modem for telephone service.

Number of Telephone Devices

The RJ-11 telephone-style connectors on the cable modem can each provide
telephone service to multiple telephones, fax machines, and analog modems. The
maximum number of telephone devices connected to each RJ-11 port is limited by
the total Ringing Load of the telephone devices that are connected. Many telephone
devices are marked with a Ringer Equivalent Number (REN). Each telephone port
on the cable modem can support up to a 5 REN load. The sum of the REN load on all
of the telephone devices attached to each port must not exceed 5 REN.

Telephone Device Types

You can use telephone devices that are not labeled with a REN number, but the
maximum number of attached telephone devices cannot be accurately calculated.
With telephone devices that are not labeled, each device should be connected and
the ring signal should be tested before adding additional devices. If too many
telephone devices are attached and the ring signal can no longer be heard, telephone
devices should be removed until the ring signal works properly.

Telephones, fax machines, and other telephone devices should use the center 2 pins
of the RJ-11 connectors to connect to the cable modem telephone ports. Some
telephones use other pins on the RJ-11 connectors and require adapters in order to
work.

Dialing Requirements

All of your telephones must support Dual Tone Multi-Frequency (DTMF) touch-tone
dialing.

Important: Pulse dialing is not supported.

Telephone Wiring Requirements

The cable modem is designed to support interior telephone wiring. The maximum
distance from the unit to the most distant telephone device must not exceed 1000 feet
(300 meters). Use 26-gauge twisted-pair, or larger, telephone wiring.

Important: Connection to an existing or a new permanently installed home
telephone wiring network must be done by a qualified installer.

4001231 Rev A WebSTAR Model DPX213 VoIP DOCSIS Cable Modem User's Guide 31

Install the Cable Modem to Provide Telephone Service

Introduction

The cable modem can be used to provide telephone service for one or two telephone
lines. This section describes how to connect a single telephone, fax machine, analog
telephone modem, or other telephone device to each telephone port on the cable
modem.

Important: Connecting the cable modem permanently to the installed home
telephone wiring is not covered by this document.

Installing the Cable Modem to Provide Telephone Service

Heed the following warnings and caution, and then follow the subsequent
installation procedures to ensure proper cable modem installation and configuration
for providing telephone service.

WARNING:

• Telephone connections to an installed home telephone wiring network must

be done by a qualified installer. The cable telephone service provider may
offer professional installation and connection to the home telephone wiring
network. A fee may be charged for this service.

• Hazardous electrical voltages can exist on the telephone ports on the cable

modem and can be present on any connected wiring. Telephone wiring and
connections must be properly insulated to prevent electrical shock.
Disconnect power from the cable modem before attempting to modify any
connected telephone wiring.

Installing the Cable Modem

Follow these steps for proper cable modem installation.

1. Connect a telephone, fax machine, or analog modem to each of the
appropriate RJ-11 ports on the cable modem.

Notes:

• The cable modem provides one line of telephone service on each of the RJ-

11 connectors.

• Service must be set up and enabled by the cable telephone service

provider.

• The two center conductors on the RJ-11 connector provide electrical

connections to directly attached telephone devices or to a permanently
installed in-home telephone wiring network.

• The use of telephones that require electrical connections to other RJ-11

pins requires an adapter.

2. After all telephone connections are complete, insert the AC power adapter
cord into the DC power connector on the back of the cable modem, and then
plug the power adapter into an AC power source.

3. Connect the active RF coaxial cable to the CABLE IN connector on the back of
the cable modem.

Note: Use an optional cable signal splitter to add a TV, a DHCT or set-top
converter, or a VCR.

4. The cable modem begins an automatic search to locate and sign on to the
network that provides the telephone service.

Note: This process may take up to 5 minutes. The modem will be ready for
use when the CABLE indicator on the front panel stops blinking and
illuminates continuously .

5. Test your telephone service by lifting the receiver of each attached telephone
to verify that dial tone can be heard and that you can make and receive
telephone calls.

Note: The Line 1 or the Line 2 front panel LED status indicator also
illuminates depending on which line the telephone is connected to.
