What’s in the Box?
Make sure you have the following items before proceeding. Call your cable company
for assistance if anything is missing.
• Telephony Gateway
• Power Cord
• Quick Installation Guide
• End User License Agreement
Items You Need
If you are installing the Telephony Gateway yourself, make sure you have the fol-
low ing 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 con-
nect 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 near-
est 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 sin-
gle outlet into two. You may need a splitter if you have a TV already con-
nected 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.
Phone Cable
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.
•Information packet: your cable company should furnish you with a packet
containing information about your service and how to set it up. Read this in-
formation carefully. Contact your cable company if you have any ques tions.
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
fol lowing information ready:
• the Telephony Gateway serial number and cable MAC addresses of the unit
(printed on the back panel of the Telephony Gateway)
• the model number of the Telephony Gateway (printed on the bottom panel
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 fol-
lowing tips to enhance your system’s security:
• Keep the operating system of your computer or laptop updated with the lat-
est security patches. Run the system update utility at least weekly.
• Keep your email program updated with the latest security patches. In addi-
tion, 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 run-
ning 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
ca ble 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 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 retail ers).
The Telephony Gateway comes with one 4-foot (1.2m) Ethernet cable (the connec-
tors look like wide telephone connectors); you can purchase more cables if neces-
sary 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 gi-
gabit 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 plug-in wireless adapter. To learn more about which wireless
hardware works best with your com puter, 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.)
Battery Installation and Removal
The TG1682 Telephony Gateway supports a Lithium-Ion backup battery to provide
continued telephone service during power outages. The battery backup is not in-
tended to take the place of AC power.
Note: For safety and regulatory purposes, batteries are shipped outside of the
Telephony Gateway and must be installed.
The TG1682 supports the following battery models:
•Basic backup battery — provides up to 4 hours of backup time, depend-
ing on your Telephony Gateway model and usage. It may be light grey or
black.
Basic Battery Installation and Replacement
•Extended backup battery — provides up to 8 hours of backup time, de-
pending on model and usage. It has a strap between the battery guides.

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 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
(re duces) the signal available to the Telephony Gateway. A large number of
split ters can slow down the Internet connection and even affect your tele-
phone 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 con-
nection 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 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.
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 unwant ed 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.
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 a wireless extender to the 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)

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.
1Connect 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.
2Insert 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.
3Connect 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
com puter, hub, or broadband router.
Note: If you are connecting to a computer or an Ethernet hub with a cross-

Indicator Lights for the TG1682
The Xfinity Telephony Gateway has several LED indicator lights to assist in trouble -
shooting.
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 Tele-
phony 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 acci-
dental 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 but ton 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 Gate-
way to provide voice service without AC power.
To start the TG1682 from its battery, follow these steps:
1If a battery is already installed in the Telephony Gateway, remove it.
2Re-insert the battery into the Telephony Gateway (see Battery Installation
and Removal for details).
3Press 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, re-
move the splitters and connect the Telephony Gateway directly to the out-
let.
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 trou-
ble 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 con nec-
tion 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.
1Is 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.
2Is 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.
3Is 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.
4Is 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 re-
store dial tone, call your service provider.

5Is 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.
