Items You Need
If you are installing the Telephony Gateway yourself, make sure you have the fol-
lowing 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 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 mini-
mize or eliminate splitters between the cable jack and the Telephony Gateway.
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.

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.
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). Crimi-
nals can take advantage of open proxies to hide their identity when break-
ing 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 net-
work.
If you use the wireless LAN, make sure you enable wireless security on the
Telephony Gateway (for the same reasons that you should run only secured
proxies). See Configuring Your Wireless Connection.
