Installing and Connecting your Telephony Gateway

Before you start, make sure that:



You have contacted your cable company and verified that they provide data and

telephone service using standard DOCSIS technology.



You have all the items you need.



Cable, phone, and power outlets are available near the computer. If a cable outlet is not

conveniently located, your cable company can install a new one.

If you have ordered service, your cable company should configure the Telephony Gateway

automatically. You need only follow the instructions in this section to install and connect

the Telephony Gateway.

CAUTION

Risk of equipment damage

Only qualified installation technicians should connect the Telephony Gateway to house wiring.

Incumbent telephone service must be physically disconnected at the outside interface box before

making any connections.

Selecting an Installation Location

There are a number of factors to consider when choosing a location to install your

Telephony Gateway:



Is an AC outlet available nearby? For best results, the outlet should not be switched and

should be close enough to the Telephony Gateway that extension cords are not

required.

Installing and Connecting your Telephony Gateway



Is a cable jack available? For best performance, keep the number of splitters between

the jack and cable drop to a minimum. Each splitter attenuates (reduces) the signal

available to the Telephony Gateway. A large number of splitters can slow down the

Internet connection and even affect your telephone service.



Can you easily run cables between the Telephony Gateway’s location and the phones?



If you are connecting devices to the Ethernet ports, can you easily run cables between

the Telephony Gateway’s location and those devices?



If you want to install the Telephony Gateway on a desktop, is there enough space on

either side to keep the vents clear? Blocking the vents may cause overheating.



How close are your wireless devices? The Telephony Gateway wireless connection

range is typically 100–200 feet (30m–65m). A number of factors can affect connection

range, as described below.

Desktop Mounting Instructions

Position the Telephony Gateway so that:



air flows freely around it



the back faces the nearest wall



it will not fall to the floor if bumped or moved



the ventilation holes on the sides of the unit are not blocked

Factors Affecting Wireless Range

A number of factors can affect the usable range for wireless connections.

Increases range



Raising the unit above the devices (for example, installing the

Telephony Gateway in the upper floor of a multi-story dwelling)



Adding a wireless extender to the network

Decreases range



Lowering the unit below the devices (for example, installing the

Telephony Gateway in a basement)



Metal or concrete walls between the Telephony Gateway and other

devices



Large metal appliances, aquariums, or metal cabinets between the

Telephony Gateway and other devices



Interference and RF noise (2.4 GHz wireless phones, microwave

ovens, or other wireless networks)

Note:

Note that decreasing the range of your wireless network may be beneficial, as long as

the decreased range is sufficient for your needs. By limiting your network’s range, you reduce

interference with other networks and make it harder for unwanted users to find and connect to your

network.

Note:

Setting the transmit power level to High increases the range.

Setting it to Medium or

Low decreases the range proportionately.

Connecting the Telephony Gateway

WARNING

Risk of injury or equipment damage

Connecting the Telephony Gateway to the home’s 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 voltage. Cancelation of

telephone service is not adequate. Failure to do so may result in loss of service and/or permanent

damage to the Telephony Gateway.

1.

Connect one end of the coax cable to the cable outlet or splitter, and the other end to

the Telephony Gateway’s Cable connector (

6

). Tighten the connections by hand, then

tighten an additional 1/8 turn with a wrench.

Note:

For best performance, use high-quality coax cable and minimize or eliminate

splitters between the cable jack and the Telephony Gateway. If you are using MoCA for your

home network, MoCA filters must be installed on any legacy client devices. Your cable company

will install these filters for you.

2.

Insert the plug from the power cord into the Power connector on the back of the

Telephony Gateway (

7

) and insert the power cord into a convenient AC outlet.

The Power light on the front of the Telephony Gateway lights up, then flashes once

(refer to the LED tables shown in Using the Telephony Gateway). See

Troubleshooting

(page 38) if the Power light does not turn on.
