Items You Need
If you are installing the Telephony Gateway yourself, make sure you have the fol-
lowing 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 mini-
mize 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.

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 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.

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.

Cleaning Instructions
Clean the Telephony Gateway using only a clean, slightly moistened, cloth. Do
not use aerosols in the vicinity of the Telephony Gateway.
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, in-
stalling the Telephony Gateway in the upper floor of
a multi-story dwelling)
Adding wireless hubs in a bridge (WDS) network
Decreases range:
•
Lowering the unit below the devices (for example, in-
stalling the Telephony Gateway in a basement)
•
Metal or concrete walls between the Telephony Gate-
way 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: Decreasing the range of your wireless network may be beneficial, as long
as the decreased range is sufficient for your needs. By limiting your net-
work'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 trasmit 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 con-
nections to the previous telephone provider must be removed and the
wiring must be checked; there must not be any voltage. Cancellation 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 (F). Tighten the con-
nections 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.
2 Insert the plug from the power cord into the Power connector on the back of
the Telephony Gateway (H) 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 if the Power light does not turn on.
3 Connect one end of the Ethernet cable to any Ethernet port on the back of
the Telephony Gateway, (E) and the other end to the Ethernet port on a
computer, hub, or broadband router.
Note: If you are connecting to a computer or an Ethernet hub with a
crossover switch, use a straight-through cable.
4 Connect one end of the telephone cable to the telephone port on the back of
the Telephony Gateway (C or D). Connect the other end to the telephone.
Home Alarm Connection
If you are only using one phone, connect it to Tell (C), then connect your
home alarm to Alarm/Te12 (D).
If you are using two phones, connect the first phone and your home alarmto
Tell (C) using an RJ-31X jack. Connect the second phone to Alarm/Te12 (D).

Indicator Lights for the TG1682
The Xfinity Telephony Gateway has several LED indicator lights to assist in
troubleshooting.
Wiring Problems
If the Telephony Gateway begins flashing all its lights for more than 10 seconds,
this indicates a problem with the telephone wiring — the red and green wires may
be shorted (touching), or there may be undesired voltage on the lines. If this
pattern persists for more than 10 seconds, disconnect the telephone lines from
the Telephony Gateway, then call a wiring technician for assistance.

Using the Reset Button
Use the Reset button, on the back of the Telephony Gateway, to reset the
modem and perform initialization as if you power cycled the unit. You may need
to reset the Telephony Gateway if you are having problems connecting to the
Internet. Using this button will be rare.
Use a pointed non-metallic object to press this button. The photo to the left
shows the location of the Reset button. The Reset button is recessed to prevent
accidental resets.
The diagram on the left shows the location of the reset button.
Resetting the Router to Factory Defaults
To reset the router to factory defaults, press and hold the Reset button on the
back of the Telephony Gateway for more than fifteen seconds. This restores the
wireless setup configuration and router configuration parameters to the factory
defaults. You may need to do this if a misconfiguration has locked out all access.
Booting from Battery
The TG1682 supports a "Boot from Battery" feature that allows the Telephony
Gateway to begin service without AC power.
To start the TG1682 from its battery, follow these steps:
1 If a battery is already installed in the Telephony Gateway, remove it.
2 Re-insert the battery into the Telephony Gateway (see Battery Installation
and Removal for details).
3 Press the Reset button; the Power light should turn on immediately.

Troubleshooting
The Telephony Gateway is plugged in, but the Power light is off.
Check all power connections. Is the power cord plugged in firmly at both
ends?
If you plugged the power cord into a power strip, make sure the strip is
switched on.
Avoid using an outlet controlled by a wall switch, if possible.
Finally, check the fuse or circuit breaker panel.
I'm not getting on the Internet (all connections).
It may take over 30 minutes to establish a connection the first time you
power up your Telephony Gateway, especially when many people are
online. Always leave your Telephony Gateway plugged into AC power and
connected to the cable system.
Check the front panel lights:
The Power and Online lights should be on.
If the Power light blinks for more than 30 minutes, call your cable
company for assistance.
Check your cable connections. Connectors should be tight. The coax cable
should not be pinched, kinked, or bent sharply—any of these can cause a
break or short in the cable (you may have to replace the cable). If you
have one or more splitters between the Telephony Gateway and CATV
outlet, remove the splitters and connect the Telephony Gateway directly to
the outlet.
Proceed to the Ethernet or wireless solutions (next page) if necessary.

I'm not getting on the Internet. (Ethernet)
If you are using a hub, is the hub turned on?
Are you using the right type of Ethernet cable? Use a straight-through
cable for direct connection to a computer; use a cross-over cable for
connection to a hub without a cross-over switch.
Press the Reset button on the back of the Telephony Gateway.
A misconfiguration could lock out all access to the Telephony Gateway router.
If you think this has happened, see Resetting the Router to Factory Defaults.
I'm not getting on the Internet. (Wireless)
Check the indicator lights (see Using the Telephony Gateway) — the WiFi
light should be on.
Does your connection utility discover your wireless LAN? If you turned off
"Broadcast SSID" you need to manually enter the name of your wireless
LAN in the connection utility.
Change your security mode to "disabled". Enable one of the other security
modes as soon as you find the problem.
A misconfiguration could lock out all access to the Telephony Gateway router.
If you think this has happened, see Resetting the Router to Factory Defaults.
My wireless Internet connection stops working sometimes.
This is usually caused by interference — two common sources are 2.4GHz
"remote" telephones and microwave ovens. If you cannot remove the inter-
fering product, try using a different channel or setting Protected Mode.
I can get on the Internet, but everything is slow.
If the Web site you are visiting is very popular, that site may be having
trouble servicing all the requests. If other sites download quickly, wait for
a few minutes and try again. Usage during peak hours may also affect the
connection speed.
Other communications on the LAN, or interference with wireless connec-
tions, may slow down your connection.

I don't have dial tone when I pick up my phone, why?
In order for telephone service to be functional on the Telephony Gateway,
telephone service must have been purchased from the service provider
and configured on your Telephony Gateway. The following steps should
help in identifying the source of the problem.
1 Is the Power LED lit?
If not, check to make sure the Telephony Gateway is plugged in
and the outlet has power.
If the LED is lit, go to the next step.
2 Is the Online LED lit?
If not, check the coax connection at the Telephony Gateway and
the wall. Ensure they are connected and tight. If they are and
you do not have dial tone, contact your service provider.
If the Online LED is lit, go to the next step.
3 Is the Telephone (Tel 1 or Tel 2) LED lit?
If not, phone service has not been set up on that line. Contact
your service provider.
If it is blinking, there is a phone off hook somewhere in the
house. Find that phone and hang it up.
If it is lit, go to the next step.
4 Is the phone plugged directly into the Telephony Gateway?
Make sure the phone is plugged into the port on the back of the
Telephony Gateway labeled "Tel 1" for line 1, and "Alarm/Tel 2"
for line 2.
If so, try a different phone. Make sure the new phone is a work-
ing phone.
If a known good phone is used and you still don't have dial
tone, try a different phone cable. If a new phone and cable do
not restore dial tone, call your service provider.

5 Is the Telephony Gateway plugged into a wall outlet?
If so, unplug the RJ-11 connector at the back of the Telephony
Gateway and plug in a known working phone. If you now have
dial tone, the problem is with the house wiring. Contact your
cable company or a qualified wiring technician to correct the
house wiring. If you still do not have dial tone, contact your serv-
ice provider.

Glossary
The following is a list of common cable and networking terms.
Amp-hour (Ah)
A measure of battery capacity. For example, a 1.0Ah battery can
nominally supply one Ampere of current for one hour.
Category 5e (CatSe)
A high-quality type of cable, used for gigabit Ethernet (1000BaseT) connec-
tions. When purchasing Ethernet cables, always look for Category 5e cable.
Coaxial cable (coax)
A thin wire, used to connect your television and Telephony Gateway to the
cable TV system. You can buy coax from any electronics retailer and many
discount stores.
CPE
Customer Premise Equipment. This is the equipment that is plugged in to
the Telephony Gateway; typically a computer or hub.
Cross-over
An Ethernet cable used to connect two hubs (or a hub and a cable modem)
together. Also, some Ethernet hubs may have built-in cross-over on one or
more ports (which eliminates the need for a cross-over cable).
DHCP
Dynamic Host Configuration Protocol. An IP protocol used to provide an IP
address and location of services (such as DNS and TFTP) needed by a de-
vice connecting to the network. DHCP allows the cable company to
configure your computer's networking software for you.
DNS
Domain Name Service (Server). An IP service that associates a domain
name (such as www.example.com) with an IP address.

Downstream
In an HFC network, the direction from the head-end to the subscriber.
Some older cable documentation may refer to this as the forward path.
DOCSIS
Data Over Cable System Interface Specification. The interoperability stan-
dards used for data communications equipment on an HFC network.
EMTA
Embedded Multimedia Terminal Adapter. An MTA device that is integrated
with a cable modem.
Ethernet
A standard method of connecting two or more computers into a Local Area
Network (LAN).
EuroDOCSIS
The European version of DOCSIS.
Event
An informational message used for monitoring network status.
F-connector
The type of connector used on coax cable. There are two common types of
F-connector, slip-on and screw-on. Use coax with screw-on connectors for
connecting your Telephony Gateway.
Firewa II
A hardware or software device that prevents unauthorized access to a pri-
vate network from the Internet. The TG1682 provides a built-in firewall.
Gateway
The device, usually a router, that connects devices on a given IP subnet to
other IP subnets.

Headend
The "central office" in an HFC network. The headend houses both video
and data equipment. In larger cable networks, a "master" headend often
feeds several "remote" headends to provide distributed services.
HTTP
HyperText Transfer Protocol.
H u b
A box with several Ethernet connectors. Ethernet hubs provide a common
point of contact for all connected devices.
IP address
A number assigned to your computer by your cable company, used to
identify your computer to other systems on the Internet.
ISD N
Integrated Services Digital Network. A digital telephony standard that pro-
vides communication speeds about twice as fast as standard dialup.
L A N
Local Area Network. A network that allows computers in a single location
(such as a building) to communicate with one another.
L E D
Light Emitting Diode. A semi-conductor diode that emits light when current
is passed through it.
MAC address
A number that uniquely identifies any device connected to a network. Your
cable company uses your Telephony Gateway's MAC address to authorize
access to the Internet. The MAC address is printed on a label on the
bottom of your Telephony Gateway.
Protocol
A set of rules and formats that determines the communication behavior of
network entities at a given layer.

Pr oxy
A device or program that stands in between a server (for example, a web
site) and a client (your browser), providing a way to relieve some of the
burden from the server. For example, your cable company may have a web
proxy that keeps copies of popular web pages; the proxy can send you those
pages instead of fetching them directly from the web site, resulting in faster
page loading and less network congestion.
RF
Abbreviation for Radio Frequency. Some literature refers to coax as "RF
cable" and the connectors as "RF connectors."
FU-11
A standard 2-conductor modular connector, commonly used in North
America for connecting telephones.
R3-45
A standard 8-conductor modular connector, commonly used on Ethernet
cable. An RJ-45 connector looks like a wide RJ-11 (telephone) connector.
Splitter
A small box with three cable connectors: one input and two outputs. You
may need a splitter if you have a TV already connected to the cable outlet
that you want to use for your Telephony Gateway. You can buy a splitter
from any electronics retailer and most discount stores.
SSID
Service Set IDentifier, a string of text (up to 32 characters long) that
uniquely identifies a wireless LAN.
Switched outlet
A power outlet that may be turned on and off using a wall switch. Usually
intended for lamps. Avoid plugging your computer or Telephony Gateway
into a switched outlet to avoid disruptions.
TCP/IP
Transmission Control Protocol/Internet Protocol. The protocols used to
facilitate communications across one or more connected networks.

T D M A
Time Division Multiple Access. A method used by DOCSIS-compliant cable
modems for sending upstream data with minimal interference.
U pstrea m
The path from a subscriber device to the headend. Some older cable docu-
mentation may refer to this as the return path or reverse path.
W E P
Wired Equivalent Privacy, a common standard for encrypting data sent over a
wireless LAN.
W P A
Wi-fi Protected Access, a standard for encrypting data sent over a wireless
LAN. WPA offers improved security over WEP.
