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. The Model ECM 615 modem comes equipped with RJ-45 Ethernet and USB
connectors, 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.
NOTE: If you have connected the Terayon ECM 615 modem to
your computer using a USB port, your computer will
prompt you to load a USB driver as soon as you apply
power to the modem. Insert the USB Drivers CD that
came with the modem into your CD-ROM drive and
follow the online instructions. You may have to tell the
computer what drive your CD-ROM drive is.
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 Online and Link LED indicators on the modem front panel are ON.
If the Online and Link LEDs are ON and not blinking, you have successfully
installed your new Terayon cable modem. If the Online and Link LEDs are
not ON or are blinking, see “Troubleshooting” on page 18.

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
Online LED, you cannot obtain additional IP
addresses unless your subscription allows for more
than one IP address. Contact your cable operator for
more information.
NOTE

FAQs
Terayon DOCSIS 615 Cable Modem Installation Guide 17
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.

Troubleshooting
18 Terayon DOCSIS 615 Cable Modem Installation Guide
TROUBLESHOOTING
Troubleshooting
Problem:
I cannot access my E-mail or Internet Service.
Possible solution:
Check all connections. Make sure the cable line is securely connected to the cable
jack on the back of the modem. Verify the Ethernet or USB cable is securely
plugged into both the modem and your network interface card or USB network
interface. Make sure your Power Adaptor is properly plugged into both the
modem and a wall outlet or surge protector. If your cable modem is properly con-
nected, the Online and Link indicator lights on the modem front panel should be a
solid color.
If the Online and Link indicator lights (LEDs) are solid green (not blinking), your
cable modem is operating properly. Try shutting down and powering off your
computer and then turning it back on. This will cause your computer to re-estab-
lish communications with your cable company server.
1. If you are using the cable line splitter, try bypassing the splitter by discon-
necting it and running a single coaxial cable between the cable modem and
your cable wall jack. Try reconnecting after making this change. If recon-
necting is successful, you may have a bad splitter.
2. Your network interface card may be malfunctioning. Refer to the Manufac-
turer's documentation for troubleshooting information.
3. Call your cable company to verify their service is two-way. This modem is
designed for use with two-way cable plants. Verify your account is activated.
