Touchstone WTM652 Telephony Modem User’s Guide
Ethernet or Wireless?
There are two ways to connect your computer (or other equipment) to the Tele-
phony Modem. 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 WTM652 through the Eth-
ernet ports, you need an Ethernet hub (available at computer retailers).
The Telephony Modem package comes with one 6-foot (1.9m) 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 Modem di-
rectly to a computer, or to an Ethernet hub with a cross-over switch, ask for Cate-
gory
5 (CAT5) straight-through cable. If you are connecting the Telephony Modem
to an Ethernet hub without a crossover switch, ask for a Category 5 crossover cable.
Wireless
The 802.11 wireless LAN standard allows one or more computers to access the
WTM652 using a wireless (radio) signal. You can use the wireless connection if your
computer has a built-in or aftermarket wireless card.
Note
:
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 others. To connect five or more computers to the Ethernet ports, you
will need an Ethernet hub (available at computer retailers).
For more information about connecting two or more computers, contact your cable
service provider.

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 Modem.
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
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 Modem (for the same reasons that you should run only secured
proxies). See “Wireless Configuration” for help.

Battery Installation and Removal
(WTM652G only)
Many Telephony Modem models support an optional Lithium-Ion backup battery.
The WTM652G supports the following battery models:
•
Basic backup battery
— provides up to 5 hours (black) or 8 hours (grey)
of backup time, depending on your Telephony Modem model and usage. It
may be light grey (recommended battery) or black.
•
Extended backup battery
— provides up to 12 hours of backup time, de-
pending on model and usage. It has a strap between the battery guides.
•
Maximum backup battery
— provides up to 24 hours of backup time, de-
pending on model and usage. It replaces the battery door, and increases the
height of the Telephony Modem by about 5/8 inch (16 mm).
