Chapter 1: Connections and Setup

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 DOCSIS compliant and PacketCable compliant technology.



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 internet service

work for you.

Illustrations contained in this document are for representation only.

Chapter 1: Connections and Setup

Contact Your Local Cable Company

You will need to contact your cable company to establish an Internet account before you can use your

gateway. You should have the following information ready (which you will find on the sticker on the

gateway):

• The serial number

• The model number

• The Cable Modem (CM) Media Access Control (MAC) address

• The Terminal Adapter (EMTA) MAC address

• Security information: Service Set IDentifier (SSID), Encryption key / passphrase (WPA2-PSK

by default), channel number. Default values are indicated underneath the modem on the sticker.

Please verify the following with the cable company

 The cable service to your home supports DOCSIS compliant two-way modem access.

 Your internet account has been set up. (The Media Terminal Adapter will provide data service if

the cable account is set up but no telephony service is available.)

 You have a cable outlet near your PC and it is ready for Cable Modem service.

Note: It is important to supply power to the modem at all times. Keeping your modem plugged in will

keep it connected to the Internet. This means that it will always be ready whenever you need.

Chapter 1: Connections and Setup

Telephone or Fax Connection

When properly connected, most telephony devices can be used with the Wireless Voice Gateway just as

with a conventional telephone service. To make a normal telephone call, pick up the handset; listen for a

dial tone, 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 Wireless Voice Gateway.

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 Wireless Voice Gateway.

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 Wireless

Voice Gateway. 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 Wireless Voice Gateway. (Other phones can be added to

each line by using standard phone line splitters.
