About this Manual
This manual covers the Touchstone TG1662G Telephony Gateway. The model number is on
the label affixed to the Telephony Gateway.

1. Model Number
2. Security Label

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 the operating system of your computer 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 service provider’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). Criminals can take advantage of open
proxies to hide their identity when breaking into other computers or sending spam. If you
have an open proxy, your service provider may suspend your account to protect the rest
of the network.
The TG1662G ships with wireless LAN security set by default (for the same reasons that
you should run only secured proxies). See the security label on your product for the
factory security settings. If you need to modify the default wireless security settings, see
Configuring Your Wireless Connection (page 31).

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 TG1662G through the Ethernet ports, you
need an Ethernet hub (available at computer retailers).
The Telephony Gateway package 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 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 access the TG1662G 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 aftermarket plugin wireless adapter. 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.)










Is a cable jack available? For best performance, keep the number of splitters 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 cables between the
Telephony Gateway’s location and those devices?
If you want to mount the Telephony Gateway on a wall, does the location provide a solid
surface for secure attachment? For best results when mounting the Telephony Gateway
on drywall, position the Telephony Gateway so at least one of the screws are fastened to a
stud. This may prevent the Telephony Gateway from pulling out of the wall in the future.
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.

Factors Affecting Wireless Range
A number of factors can affect the usable range for wireless connections.
Increases range



Decreases range



Raising the unit above the devices (for example, installing the Telephony
Gateway in the upper floor of a multi-story dwelling)
Adding a wireless extender to the network
Lowering the unit below the devices (for example, installing the
Telephony Gateway in a basement)
Metal or concrete walls between the Telephony Gateway 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: 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 unwanted users to find and connect
to your network.
Note: Setting the transmit power level to High increases the range. Setting it to Medium or
Low decreases the range proportionately.

Mounting the Telephony Gateway
You can either mount the Telephony Gateway on a wall or place it on a desktop. For wallmount applications, you can mount the Telephony Gateway with the indicators facing upward
(vertical) or to the side (horizontal).

Tools and Materials
For wall-mounted installations, make sure you have the following tools and materials before
proceeding:
 for mounting on drywall: Two 1/4” (6mm) drywall anchors (not included), two #6 x 1.5”
(38.1 mm) self-tapping panhead screws (not included), and a drill with 1/4” (6mm) bit (not
included)
 for mounting on plywood or studs: two #6 x 1.5” (38.1 mm) self-tapping panhead wood
screws (not included)
 screwdriver (flat-blade or Phillips, depending on what kind of screws you use)
 wall-mounting bracket (order from your service provider)

Location
Always position the Telephony Gateway:
 within reach of an AC outlet. The power cord must reach the outlet without stretching and
without adding extension cords.
 near a cable outlet (to avoid long cable runs).

Wall Mounting Instructions
Note: When mounting the Telephony Gateway on drywall, try to position the Telephony
Gateway so at least one of the screws is fastened to a stud. This may prevent the Telephony
Gateway from pulling out of the wall in the future. To prevent overheating of the Telephony
Gateway, do not block the ventilation holes on the sides of the unit.
1. Position the mounting bracket on the surface where you intend to mount the Telephony
Gateway and mark the two holes with a pencil.

Chapter 5: Installing and Connecting your Telephony Gateway
2. Drill holes for the mounting screws through the marked locations.

3. If using drywall anchors, set them into the wall. Then, drive the screws into the wall
leaving a gap of about 1/8” (3 mm) between the screw head and the wall. If not using
anchors, just drive the screws.

4. Slip both mounting slots in the back of the mounting bracket over the screws, then slide
the bracket down until the narrow end of the keyhole slot contacts the screw shaft.

5. Hang the Telephony Gateway on the wall by inserting the six tabs on the mounting bracket
into the six slots in the back of the Telephony Gateway and sliding the Telephony Gateway
down until it drops in place on the bracket.

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 connections to the previous telephone provider
must be removed and the wiring must be checked; there must not be any voltage. Cancelation
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 (6). Tighten the connections 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. If you are using MoCA for
your home network, MoCA filters must be installed on any legacy client devices. Your
service provider will install these filters for you.
2. Insert the plug from the power cord into the Power connector on the back of the

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.
Try to plug the power cord into a different outlet. If the outlet is controlled by a wall switch,
make sure the switch is on.
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 service provider 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

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 (page 43).

I'm not getting on the Internet (Wireless)
Check the indicator lights, see Using the Telephony Gateway (page 38) — the Wi-Fi 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.

has happened, see Resetting the Router to Factory Defaults (page 43).

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 interfering 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 connections, may slow down
the connection.

I don't have a dial tone when I pick up the 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. Use only the external AC power adapter (if provided) and power cord included
with the equipment.

Chapter 8: Troubleshooting

• 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 “Tel 2” for line 2.
• If so, try a different phone. Make sure the new phone is a working 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 phone 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 service provider or a qualified wiring technician to correct the
house wiring. If you still do not have dial tone, contact your service provider.

Glossary
A
Amp-Hour
A measure of battery capacity. For
example, a 1.0Ah battery can nominally
supply one Ampere of current for one
hour.

C
Category 5e (Cat5e)
A high-quality type of cable, used for
gigabit Ethernet (1000BaseT) connections.
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).

D
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 device 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.

DOCSIS
Data Over Cable System Interface
Specification. The interoperability
standards used for data communications
equipment on an HFC network.

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.

E
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).
