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 (page 10) for a list of items in the
package.
Coaxial cable (coax): 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 Data Gateway.
Phone Cable: This is a standard phone cable with standard phone connectors (RJ11 type)

© 2017 ARRIS Enterprises LLC. All Rights Reserved. 12
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.
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.
Information packet: your service provider should furnish you with a packet containing
information about your service and how to set it up. Read this information carefully and
contact your service provider if you have any questions.

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
the Telephony Gateway)
the model number of the Telephony Gateway (printed on the Telephony Gateway)
If the Telephony Gateway was provided by your service provider, they already have the
required information.
In addition, you should ask your service provider the following questions:
Do you have any special system requirements or files that I need to download 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?
System Requirements

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.
DRAFT
Chapter 3: Getting Started
Release 34 DRAFT 1.6 June 2017 Touchstone TG3452 Telephony Gateway User Guide
© 2017 ARRIS Enterprises LLC. All Rights Reserved. 15
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 TG3452 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.
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 TG3452 through the Ethernet ports, you
need an Ethernet hub (available at computer retailers).
DRAFT
Chapter 3: Getting Started
Release 34 DRAFT 1.6 June 2017 Touchstone TG3452 Telephony Gateway User Guide

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
TG3452 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
plug-in 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.)

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 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 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:
it stands vertically on its base (Do not lay it flat on its side.)
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 sides of the unit are not blocked
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, installing 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, 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.

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
to the outlet.
Proceed to the Ethernet or wireless solutions 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 the supplied cable for direct connection
to a computer; use a cross-over cable for connection to a hub.
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 (page 36).
I'm not getting on the Internet (Wireless)
Check the indicator lights, see Using the Telephony Gateway (page 31) — 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.
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 36).
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.
• 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.
