Installing and Connecting Your
Telephony Modem
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.
CAUTION
Risk of equipment damage
Only qualified installation technicians should connect the Telephony
Modem to house wiring. Incumbent telephone service must be physi-
cally 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 Modem:
Is an AC outlet available nearby? For best results, the outlet should not be
switched and should be close enough to the Telephony Modem that exten-
sion cords are not required.
Is a cable jack available? For best performance, keep the number of split-
ters between the jack and cable drop to a minimum. Each splitter attenuates
(reduces) the signal available to the Telephony Modem. A large number of
splitters can slow down the Internet connection and even affect your tele-
phone service.
Can you easily run cables between the Telephony Modem’s location and the
phones?
If you are connecting devices to the Ethernet ports, can you easily run ca-
bles between the Telephony Modem’s location and those devices?
If you want to mount the Telephony Modem on a wall, does the location pro-
vide a solid surface for secure attachment? For best results when mounting
the Telephony Modem on drywall, position the Telephony Modem so at least
one of the screws are fastened to a stud. This may prevent the Telephony
Modem from pulling out of the wall in the future.
If you want to install the Telephony Modem 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 Modem wireless connec-
tion range is typically 100–200 feet (30m–65m). A number of factors can af-
fect connection range, as described below.

Factors Affecting Wireless Range
A number of factors can affect the usable range for wireless connections.
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 unwant-
ed users to find and connect to your network.
Increases range:
Raising the antenna above the devices (for example,
installing the Telephony Modem in the upper floor of a
multi-story dwelling or using an aftermarket omnidi-
rectional antenna)
Using an aftermarket directional antenna (increases
range in one direction while decreasing range in other
directions)
Adding wireless hubs in a bridge (WDS) network
Decreases range:
Lowering the antenna below the devices (for example,
installing the Telephony Modem in a basement)
Removing the antenna
Metal or concrete walls between the Telephony Modem
and other devices
Large metal appliances, aquariums, or metal cabinets
between the Telephony Modem and other devices
Interference and RF noise (2.4 GHz wireless phones,
microwave ovens, or other wireless networks)
