About this Manual
This manual covers the Xfinity TG1682 Telephony Gateway. The model number is
on the label affixed to the bottom of the Telephony Gateway. See the image at the
left.
What About Security?
Having a high-speed, always-on connection to the Internet requires a certain amount
of responsibility to other Internet users—including the need to maintain a reasonably
secure system. While no system is 100% secure, you can use the following tips to
enhance your system's security:
Keep your operating system updated with the latest security patches. Run the
system update utility at least weekly.
Keep your email program updated with the latest security patches. In addition,
avoid opening email containing attachments, or opening files sent through
chat rooms, whenever possible.
Install a virus checker and keep it updated.
Avoid providing web or file-sharing services over your Telephony Gateway.
Besides certain vulnerability problems, most cable companies prohibit running
servers on consumer-level accounts and may suspend your account for
violating your terms of service.
Use the cable company's mail servers for sending email.
Avoid using proxy software unless you are certain that it is not open for
abuse by other Internet users (some are shipped open by default). Crimi-
nals can take advantage of open proxies to hide their identity when break-
ing into other computers or sending spam. If you have an open proxy, your
cable company may suspend your account to protect the rest of the net-
work.
If you use the wireless LAN, make sure you enable wireless security on the
Telephony Gateway (for the same reasons that you should run only secured
proxies). See Configuring Your Wireless Connection.

Ethernet Cable
A R R I S
Getting Battery Ethernet
Safety Started Installation Installation Configuration Usage Troubleshooting Glossary
Ethernet or Wireless?
There are two ways to connect your computer (or other equipment) to the Tele-
phony Gateway. The following will help you decide which is best for you:
Ethernet
Ethernet is a standard method of connecting two or more computers into a Local
Area Network (LAN). You can use the Ethernet connection if your computer has
built-in Ethernet hardware.
Note: To connect more than four computers to the TG1682 through the Ether-
net ports, you need an Ethernet hub (available at computer retailers).
The Telephony Gateway comes with one 4-foot (1.2m) Ethernet cable (the
connectors look like wide telephone connectors); you can purchase more cables if
necessary at a computer retailer. If you are connecting the Telephony Gateway
directly to a computer, or to an Ethernet hub or broadband router with a cross-
over switch, ask for Category 5e (CAT5e) straight-through cable. CAT5e cable is
required for gigabit Ethernet (Gig-E), not regular CAT5 cable
Wireless
Wireless access lets you connect additional (wireless-capable) devices to Telephony
Gateway. The 802.11 wireless LAN standard allows one or more computers to ac-
cess the TG1682 using a wireless (radio) signal. These connections are in addition
to the connections supported via Ethernet.
Note: You can use the wireless connection if your computer has a built-in or af-
termarket wireless card. To learn more about which wireless hardware
works best with your computer, see your computer dealer.
Both
If you have two or more computers, you can use Ethernet for up to four devices
and wireless for the others. To connect five or more computers to the Ethernet
ports, you will need an Ethernet hub (available at computer retailers.)

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.
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 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 ca-
bles 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 side of the unit are not blocked.
