Items You Need
If you are installing the Telephony Gateway yourself, make sure you have the fol-
low 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 con-
nect 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 near-
est 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 sin-
gle outlet into two. You may need a splitter if you have a TV already con-
nected 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.
•Ethernet Cable(s): as shown in the image to the left, this is a Category 5e
(CAT5e) straight-through cable for connecting computers to the Gateway.
Phone Cable

•Wall-mount hardware (optional): if you want to wall-mount your Tele-
phony Gateway, you need to obtain two drywall anchors or wood screws.
See the Wall-Mount Template and Instructions for more details.
•Information packet: your cable company should furnish you with a packet
containing information about your service and how to set it up. Read this in-
formation carefully. Contact your cable company if you have any ques tions.
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
fol lowing information ready:
• the Telephony Gateway serial number and cable MAC addresses of the unit
(printed on a sticker on the bottom of the Telephony Gateway)
• the model number of 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 down-
load 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?

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 fol-
lowing 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 addi-
tion, 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 run-
ning 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
ca ble 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.
