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) 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.

Getting Started
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 cable company should furnish you with a packet
containing information about your service and how to set it up. Read this information
carefully and 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
the Telephony Gateway)
the model number of the Telephony Gateway (printed on 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 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
The Touchstone Telephony Gateway operates with most computers. The following
describes requirements for each operating system; see the documentation for your system
for details on enabling and configuring networking.
To use the Telephony Gateway, you need DOCSIS high-speed Internet service from your
cable company. Telephone service requires that the cable company has PacketCable
support.
Recommended Hardware
The following hardware configuration is recommended. Computers not meeting this
configuration can still work with the TG2472, but may not be able to make maximum use
of TG2472 throughput.
CPU: P4, 3GHz or faster
RAM: 1GB or greater
Hard drive: 7200 RPM or faster

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 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). 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 cable company may suspend your account to
protect the rest of the network.
The TG2472 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 TG2472 through the Ethernet ports, you
need an Ethernet hub (available at computer retailers).

Getting Started
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
TG2472 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.)
