Connecting the CATV Coaxial Cable to the Modem
In order for your cable modem and your computer to access the Internet, you need
to connect the coaxial cable that comes from your cable outlet to the modem. This
is typically done using a cable splitter. See Figure 2 on page 4.
To connect your modem to the CATV coaxial cable, follow these steps:
1. Locate the CATV coaxial cable connected to the cable outlet.
You can find it in one of three ways:
• It may be connected to a TV, Converter Box, or a VCR.
• It may be connected to a wall mounted outlet.
• It may be coming out from under a baseboard or some other location.
2. When you locate the CATV coaxial cable, disconnect it from the TV, Con-
verter Box, or VCR.
You may need to use a wrench to disconnect the cable.
3. Locate the cable splitter, then using Figure 2 and Figure 4 as guides, connect
the CATV coax cable you disconnected in step 2 to the IN connector on the
cable splitter. Tighten the connector with a 7/16 inch wrench.

Connecting the Modem to your PC
In order for your computer to communicate with your new modem and the Inter-
net, it must be equipped with a network interface. Today’s computers are typically
equipped with either a 10 Base-T Ethernet port or a Universal Serial Bus (USB)
port. TJ 700 Series modems come equipped with RJ-45 Ethernet and USB con-
nectors, allowing the modem to connect to either an Ethernet port or a USB serial
port. To connect your new modem to your PC, do the following:
1. Before you begin connecting the modem to your PC, look in your computer
user manual or look at the back of your PC to see what kind of network inter-
face your PC is equipped with.
IMPORTANT: If you do not have a network interface installed
in your computer, you will need to purchase one
from a retailer or your local cable company, and
install it according to manufacturer instructions.
2. If your PC is equipped with a 10 Base-T Ethernet card, proceed to “Connect-
ing the 10 Base-T Ethernet Cable” on page 10. If your PC is equipped with a
USB Serial Port, proceed to “Connecting the USB Cable” on page 12.
IMPORTANT: Do not connect the modem to both the PC Ether-
net and the USB port. Use either the USB or the
Ethernet port, not both. Note that the Ethernet
connection is preferable to the USB connection if
both are available. The Ethernet connection is
the fastest speed connection and will not be
shared with other devices.

Starting the Modem
To start operating your new Terayon cable modem, do the following:
1. Plug the Power Adaptor into an appropriate AC power outlet.
Once your Terayon cable modem is properly connected and the Power
Adapter is connected to an AC power outlet, it will automatically boot-up and
start scanning for the active cable modem channel from your cable company
server.
IMPORTANT: When you power up the Terayon DOCSIS cable
modem for the first time, it can take up to 10 min-
utes for the modem to complete its boot-up and
scanning sequence. Do not turn modem power
off during the boot-up and scanning sequence,
unless your cable operator instructs you to do so.
2. Verify the Cable and PC LED indicators on the modem front panel are ON.
If the Cable and PC LEDs are ON and not blinking, you have successfully
installed your new Terayon cable modem. If the Cable and PC LEDs are not
ON or are blinking, see “Troubleshooting” on page 19.

FREQUENTLY ASKED QUESTIONS
FAQs
Q. Can I have more than one computer attached to a Terayon modem?
A. Yes, Terayon cable modems do provide this capability, but you will need to
install a hub into your system and you must arrange for this service with your
cable service provider. Some service providers limit the number of computers
connected to the modem.
Q. Can I connect the Terayon cable modem to a hub or switch?
A. Yes, you can connect the Terayon cable modem to a hub or switch. There are
two ways to successfully complete a physical connection.
1. Buy a cross-over cable and connect the port labeled 10Base-T on the Ter-
ayon cable modem to one of the ports on the hub or switch.
2. Many newer hubs and switches have an “uplink” port specifically designed
for cascading. Connect this uplink port to your Terayon cable modem and it
should work without a cross-over cable. Connect your PC to another avail-
able port.
NOTE: While you may be able to successfully complete a phys-
ical connection to a hub or switch indicated by a green
PC LED, you cannot obtain additional IP addresses
unless your subscription allows for more than one IP
address. Contact your cable operator for more infor-
mation.

FAQs
18 Terayon TJ 700 Series DOCSIS Cable Modem Installation Guide
Q. Can I down load new modem software drivers or do something to optimize
the modem configuration in order to improve my performance?
A. No, modem configuration and downloading of software drivers can only take
place over the cable TV cable and are provided by the cable operator.
But, improving the performance of your cable modem does not give the cable
operators access to your computer so your personal privacy and security are
not affected.
Q. If I don’t subscribe to cable TV, can I still get a cable modem Internet con-
nection?
A. Yes, but this is a question for your cable service provider or Broadband Ser-
vice Provider (BSP) and depends on their policies.
Q. The product specifications define varying data rates, why don’t I see those?
A. The cable operator has the flexibility to set different performance levels to dif-
ferentiate between different types of subscribers. In general, individual resi-
dential subscribers will not be allocated the entire channel bandwidth.
Q. Can I watch TV and surf the Internet at the same time?
A. Yes, neither television or data signals are affected by simultaneous use.
