Items You Need

If you are installing the Telephony Modem yourself, make sure you have the following items on hand before continuing:

• Telephony modem 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 thin 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 Modem. The coax should be long enough to reach from your Telephony Modem 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 Telephony Modem.

• 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 Modem and TV to the splitter.

• the Telephony Modem serial number and MAC addresses of the unit (printed on a sticker on the bottom of the Telephony Modem)

• the model number of the Telephony Modem

Save this information for future use. 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 Modem?

• Do I need a user ID or password to access the Internet or my e-mail?

• Will my phone number(s) change?

About this Manual

This manual covers all of the different TM722 models. Your model may not have all of the capabilities outlined in this manual. To determine which model you have purchased, refer to the image at the left. The model number is on the label afﬁxed to the Telephony Modem.

Ethernet or USB?

Model

Number

There are two ways to connect your computer (or other equipment) to the Telephony Modem. The following will help you decide which is best for you:

Ethernet

Ethernet is a standard method of connecting two or more devices into a Local Area Network (LAN). Use the Ethernet connection if your computer has built-in Ethernet hardware, does not use Windows, or you want to share the Telephony Modem connection with several computers.

Note: To connect two or more computers to the Ethernet port, you will need a

hub or broadband router (available at computer retailers).

The Telephony Modem package comes with a 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 directly to a computer, or to an Ethernet hub or broadband router with a cross-over switch, ask for Category 5 (CAT5) straight-through cable. If you are connecting the Telephony Modem to an Ethernet hub or broadband router without a crossover switch, ask for a Category 5 crossover cable.

USB

USB (Universal Serial Bus) is meant for connecting a variety of accessories, such as keyboards, mice, printers, and communications devices (including Telephony Modems) to a single computer. Use the USB connection if you have only one computer, and the computer is using a Windows operating system (Windows 2000 or later), and has no built-in Ethernet hardware. Telephony Modems with USB ports include a 5-foot (1.6m) USB cable.

Both

If you have two or more computers, you can connect one computer to the Telephony Modem’s USB port and one or more other computers to the Ethernet port. To connect two or more computers to the Ethernet port, you will need a hub or broadband router (available at computer retailers).

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 Modem. 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 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.

• If you connect your Telephony Modem to a wireless LAN, make sure you enable security and encryption on the wireless hub (for the same reasons that you should run only secured proxies). Consult the documentation and technical support of the wireless equipment provider for help.
