Items You Need
If you are installing the Telephony Gateway yourself, make sure you have the following items on hand before continuing:
Telephony Gateway package: see What's in the Box? for a list of items
in the package.
Coaxial cable (coax): as shown in the image to the left, this is a round
cable with a connector on each end. It is the same kind of wire used to
connect to your television for cable TV. You can buy coax from any
electronics retailer and many discount stores; make sure it has connectors
on both ends. There are two types of connectors, slip-on and screw-on;
the screw-on connectors are best for use with your Telephony Gateway.
The coax should be long enough to reach from your Telephony Gateway to
the nearest cable outlet.
Note: For best performance, use high-quality RG-6 type coax cable and minimize or eliminate splitters between the cable jack and the Telephony Gateway.
Phone Cable: as shown in the image to the left, this is a standard phone
cable with standard phone connectors (RJ11 type) on both ends. You can
buy phone cables from any electronics retailer and many discount stores.
Splitter (optional): provides an extra cable connection by splitting a single
outlet into two. You may need a splitter if you have a TV already connected
to the cable outlet that you want to use. You can buy a splitter from any
electronics retailer and most discount stores; you may also need a short
piece of coax cable (with connectors); use it to connect the splitter to the
cable outlet and then connect the Telephony Gateway and TV to the splitter.
Ethernet Cable
Xfinity TG1682 Telephony Gateway User's Guide 8

Getting Battery Ethernet
Safety Started Installation Installation Configuration Usage Troubleshooting Glossary
Note: A splitter effectively cuts the signal in half and sends each half to its
two outputs. Using several splitters in a line may deteriorate the quality of
your television, telephone, and/or internet connection.
Ethernet Cable(s): as shown in the image to the left, this is a Category 5e
(CAT5e) straight-through cable for connecting computers to the Gateway.
Wall-mount hardware (optional): if you want to wall-mount your Tele-
phony Gateway, you need to obtain two drywall anchors or wood screws.
See the Wall-Mount Template and Instructions for more details.
Information packet: your cable company should furnish you with a packet
containing information about your service and how to set it up. Read this information carefully. Contact your cable company if you have any questions.
Getting Service
Before trying to use your new Telephony Gateway, contact your local cable
company to establish an Internet account and telephone service. When you call,
have the following information ready:
the Telephony Gateway serial number and cable MAC addresses of the
unit (printed on a sticker on the bottom of the Telephony Gateway)
the model number of the Telephony Gateway
If the Telephony Gateway was provided by your cable company, they already
have the required information.
In addition, you should ask your cable company the following questions:
Do you have any special system requirements or files that I need to down-
load after I am connected?
When can I start using my Telephony Gateway?
Do I need a user ID or password to access the Internet or my e-mail?
Will my phone number(s) change?
What new calling features will I have and how do I use them?

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 network.
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.

Safety Started Installation Installation Configuration Usage Troubleshooting Glossary
Ethernet or Wireless?
There are two ways to connect your computer (or other equipment) to the Telephony 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 crossover 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 access 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.)
