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.

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.)
