What Are the Requirements for Telephone Service?

Number of Telephone Devices

The RJ-11 telephone-style connectors on the residential gateway 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 residential gateway 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 more 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 residential gateway telephone ports. Some

telephones use other pins on the RJ-11 connectors and require adapters in order to

work.

Dialing Requirements

All your telephones should be set to use DTMF dialing. Pulse dialing is typically not

enabled by your local provider.

Telephone Wiring Requirements

The residential gateway supports connecting to the interior telephone wiring as well

as connecting directly to a telephone or fax machine. 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.

How Do I Subscribe to High-Speed Internet and Telephone Service?

How Do I Subscribe to High-Speed Internet and Telephone

Service?

Before you can use your residential gateway, you need to have a high-speed Internet

access account. If you do not have a high-speed Internet access account, you need to

set up an account with your local service provider. Choose one of the two options in

this section.

I Do Not Have a High-Speed Internet Access Account

If you do

not

have a high-speed Internet access account, your service provider will

set up your account and become your Internet Service Provider (ISP). Internet access

enables you to send and receive e-mail, access the World Wide Web, and receive

other Internet services.

You will need to give your 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 residential gateway. 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

CM MAC

The following illustration shows a sample bar code label.

Write down these numbers in the space provided here.

Serial Number

_______________________

MAC Address

________________________

I Already Have an Existing High-Speed Internet Access Account

If you have an existing high-speed Internet access account, you must give your

service provider the serial number and the MAC address of the residential gateway.

Refer to the serial number and MAC address information listed previously in this

section.

Note:

You may not be able to continue to use your existing e-mail account with your

residential gateway. Contact your service provider for more information.

I Want to Use the Residential Gateway for Telephone Service

You will also need to set up a telephone account with your local service provider to

use your residential gateway for telephone service. When you contact your service

provider, 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 telephony service

provider.

How Do I Connect My Gateway for Internet and Telephone Service?

How Do I Connect My Gateway for Internet and Telephone

Service?

You can use your residential gateway to provide both telephone service and to

provide Internet access, and you can share that Internet connection with other

Internet devices in your home or office. Sharing one connection among many

devices is called networking.

Connecting and Installing Internet Devices

Professional installation may be available. Contact your local service provider for

further assistance.

To connect devices

The following diagram illustrates one of the various networking options that are

available to you.

How Do I Connect My Gateway for Internet and Telephone Service?

Connecting the Gateway for High-Speed Data and Telephone Service

WARNING:

To avoid personal injury, follow the installation instructions in the exact

order shown.

To prevent possible damage to equipment, disconnect any other telephone

service before connecting your cable modem to the same wires.

Hazardous electrical voltages can exist on the telephone ports on the

residential gateway and can be present on any connected wiring including

Ethernet wiring, telephone wiring and coax cable.

Telephone wiring and connections must be properly insulated to prevent

electrical shock.

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.

Wiring and connections must be properly insulated to prevent electrical

shock.

Disconnect power from the residential gateway before attempting to

connect to any device.

Power off your PC and other networking device; then, unplug them from the

power source

Connect the active RF coaxial cable from your service provider to the coax

connector labeled

CABLE

on the back of the gateway.

Note:

To connect a TV, DHCT, set-top box, or VCR from the same cable

connection, you will need to install a cable signal splitter (not included).

Locate the yellow Ethernet cable.

Connect one end of the Ethernet cable to the

Ethernet port on your PC and then connect the other end to one of the

ETHERNET ports on the gateway (any Ethernet port can be used).

The Ethernet

ports are yellow connectors on the back panel of the gateway.

Connect additional Ethernet network devices in a similar fashion to any unused

Ethernet ports on the back of the gateway.

Note:

To install more Ethernet devices than ports provided, use an external

multi-port Ethernet switch(s).

Connect one end of a telephone jumper cable (not included) to a telephone outlet

in your home or to a telephone or fax machine.

Then connect the other end of the

jumper cable to the appropriate RJ-11 TELEPHONE port on the back of the

gateway.

The telephone ports are light gray and are labeled 1/2 and 2 or 1 and 2

depending on the region of the world the gateway is used.

Notes:

–

Make sure to connect your telephone service to the correct RJ-11 port.

For

single line telephone service, connect to port 1/2 or 1.
