Chapter 2: Getting to Know the
Cable Modem with USB and
Ethernet Connection
Overview
A cable modem is a device that allows high-speed data access (such as to the
Internet) via a cable TV network. A cable modem will typically have two connections, one to the cable wall outlet and the other to a computer (PC). The fact
that the word "modem" is used to describe this device can be a little misleading only in that it conjures up images of a typical telephone dial-up modem.
Yes, it is a modem in the true sense of the word since it MOdulates and
DEModulates signals. However, the similarity ends there, as these devices are
much more complicated than telephone modems. Cable modems can be part
modem, part tuner, part encryption/decryption device, part bridge, part router,
part network interface card, part SNMP agent, and part Ethernet hub.
Cable modem speeds vary, depending on the cable modem system, cable network architecture, and traffic load. In the downstream direction (from the network to the computer), network speeds can reach 27 Mbps, an aggregate
amount of bandwidth that is shared by users. Few computers will be capable of
connecting at such high speeds, so a more realistic number is 1 to 3 Mbps. In
the upstream direction (from computer to network), speeds can be up to 10
Mbps. Check with your Cable Internet Service Provider (ISP) for more specific information about upload (upstream) and download (downstream) access
speeds.
In addition to speed, there's no need to dial in to an ISP when you are using your
Cable Modem. Simply click on your browser and you're on the Internet. No
more waiting, no more busy signals.

Reset
Button Briefly pressing and holding in the Reset button allows you to
clear the Cable Modem’s connections and resets the Cable
Modem to the factory defaults. Continued or repeated pressing
of this button is not recommended.
LAN Port This port allows you to connect your Cable Modem to your PC
or other Ethernet network device using a CAT 5 (or better) UTP
network cable.
USB Port This port allows you to connect your Cable Modem to your PC
using the included USB cable. Not all computers are able to use
USB connections. For more information concerning USB and
compatibility with your computer, see the next section.
Cable Port The cable from your ISP connects here. It is a round coaxial
cable, exactly like the one that connects to the back of your
cable box or television.

The Back Panel
The USB Icon
The USB icon shown below marks a USB port on a PC or device.
To use this USB device, you must have Windows 98, Me, 2000, or XP installed
on your PC. If you do not have one of these operating systems, you cannot use
the USB port.
Also, this device requires that a USB port is installed and enabled on your PC.
Some PCs have a disabled USB port. If your port doesn’t seem to be working,
there may be motherboard jumpers or a BIOS menu option that will enable the
USB port. See your PC’s user guide for details.
Some motherboards have USB interfaces, but no ports. You should be able to
install your own USB port and attach it to your PC’s motherboard using hardware purchased at most computer stores.
Your Cable Modem with USB and Ethernet Connection comes with a USB
cable that has two different types of connectors. Type A, the master connector,
is shaped like a rectangle and plugs into your PC’s USB port. Type B, the slave
connector, resembles a square and connects to the USB port on the back panel
of your Cable Modem.
USB Type A
USB Type B
There is no USB Support on PCs running
Windows 95 or Windows NT.

Chapter 3: Connecting the
Cable Modem to Your PC
Connecting Using the Ethernet Port
1. Make sure that you have TCP/IP installed on your computer. If you don’t
know what TCP/IP is or you don’t have it installed, refer to the section in
“Appendix B: Installing the TCP/IP Protocol.”
2. If you have an existing cable modem that you are replacing, disconnect it at
this time.
3. Connect the coaxial cable from your ISP/Cable Company to the Cable Port
on the back of the Cable Modem. The other end of the coaxial cable should
be connected in the manner proscribed by your ISP/Cable Company.
4. Connect a UTP CAT 5 (or better) Ethernet cable to the LAN Port on the back
of the Cable Modem. Connect the other end of the cable to the RJ-45 port
on your PC’s Ethernet adapter or your hub/switch/router.
5. With your PC turned off, connect the power adapter included in your package to the Power Port on the back of the Cable Modem. Plug the other end
of the power cord into a standard electrical wall socket. The Power LED on
the front of the Cable Modem should light up and remain on.
6. Contact your Cable ISP to activate your account. Usually, your Cable ISP
will need what is called a MAC Address for your Cable Modem in order to
set up your account. The 12-digit MAC address is printed on a bar code label
on the bottom of the Cable Modem. Once you have given them this number,
your Cable ISP should be able to activate your account.
The Hardware Installation is now complete.
Your Cable Modem is ready to use.
Power (Green) When this LED is on, it indicates that the Cable Modem
is correctly supplied with power.
Link/Act (Green) This LED becomes solid when the Cable Modem is
properly connected to a PC, either through an Ethernet or USB
cable. The LED flashes when there is activity on this connection.
Send (Green) This LED is solid or will flash when data is being trans-
mitted through the Cable Modem interface.
Receive (Green) This LED is solid or will flash when data is being
received through the Cable Modem interface.
Cable (Green) This LED will go through a series of flashes as the
Cable Modem goes through its startup and registration process.
It will remain solid when registration is complete, and the Cable
Modem is fully operational. The registration states are displayed
