Items You Need
If you are installing the Telephony Gateway yourself, make sure you have the follow 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 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 screwon 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.
Coax Cable
Phone Cable
• 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 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.
• Wall-Mounting Bracket (optional): if you want to wall-mount your Telephony Gateway, you need to obtain two drywall anchors or wood screws and
order a wall-mounting bracket from your cable company.

About this Manual
This manual covers the Touchstone TG1672 Telephony Gateway. The model number is on the label affixed to 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 following tips to enhance your system’s security:
• Keep your operating system 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.
Model
Number
Security
Label
• 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
ca ble company may suspend your account to protect the rest of the network.
• The TG1672 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 (shown on image at the left) 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 TG1672 through the Ether-
net ports, you need an Ethernet hub (available at computer retail ers).
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 TG1672 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 wireless card. 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.)
