Internet service, or both services. Your cable service provider enables Internet
service. Contact your cable service provider for more information if you are not
currently subscribing to Internet service.
Q. How many telephones can I connect?
A. The RJ-11 telephone-style connectors on the cable modem can each provide
telephone service to multiple telephones, fax machines, and analog modems.
The maximum number of telephone devices connected to each RJ-11 port is
limited by the total Ringing Load of the telephone devices that are connected.
Many telephone devices are marked with a Ringer Equivalent Number (REN).
Each telephone port on the cable modem can support up to a 5 REN load. The
sum of the REN load on all of the telephone devices attached to each port must
not exceed 5 REN.
Q. Can I surf the Internet and make telephone calls at the same time?
A. Absolutely! Telephone service is provided separately from Internet data
services. Internet surfing and other data services do not affect the quality of your
telephone calls. If these services are enabled by your cable service provider, you
can make telephone calls and surf the net at the same time.

Common Troubleshooting Suggestions
The modem does not register a cable connection.
The modem works with a standard, 75-ohm, RF coaxial cable. If you are using a
different cable, your cable modem will not function properly. Contact your cable
service provider to determine whether you are using the correct cable.
There is no dial tone when I lift the telephone handset.
• Your telephone wiring may be connected to the wrong RJ-11 port on the
cable modem. The cable modem has two telephone ports. Verify that you are
connected to the correct telephone port.
• There may be a problem with your telephone set. Use a different telephone
set and listen to hear dial tone.
• There may be a problem with your home telephone wiring. Use a telephone
and connect directly to the same RJ-11 port on the back of the unit. If the dial
tone is working here but does not work at other locations in the home, a
professional may need to diagnose and repair a problem with your telephone
wiring.
• Verify that the phone company has removed the previous telephone service
from your home telephone wiring.
• Your telephone service may not be enabled from your cable telephony
service provider. Contact your cable telephony service provider for more
information.
Frequently Asked Questions
Q. What if I don’t subscribe to cable TV?
A. If cable TV is available in your area, data service may be made available with

Tips for Improved Performance
Check and Correct
If your cable modem does not perform as expected, the following tips may help. If
you need further assistance, contact your cable service provider.
• Verify that the plug to your cable modem AC power is properly inserted into
an electrical outlet.
• Verify that your cable modem AC power cord is not plugged into an electrical
outlet that is controlled by a wall switch. If a wall switch controls the electrical
outlet, make sure the switch is in the ON position.
• Verify that the POWER and CABLE LED status indicators on the front panel
of your cable modem are illuminated.
• Verify that all cables are properly connected, and that you are using the
correct cables.
• Verify that your cable service is active and that it supports two-way service.
• Verify that your TCP/IP is properly installed and configured if you are using
the Ethernet connection.
• Verify that you have followed the procedures in How Do I Install the USB
Drivers, earlier in this guide, if you are using the USB connection.
• Verify that you have called your cable service provider and given them the
serial number and MAC address of your cable modem.
• If you are using a cable signal splitter so that you can connect the cable
modem to other devices, remove the splitter and reconnect the cables so that
the cable modem is connected directly to the cable input. If the cable modem
now functions properly, the cable signal splitter may be defective and may
need to be replaced.

FCC Privacy Statement
Privacy of communications may not be ensured when using this phone.
FCC Part 68
The Federal Communications Commission (FCC) of the United States restricts
specific uses of modems, and places registration responsibilities on both the
manufacturer and the individual user.
1. The modem may not be connected to a party line or to a coin-operated
telephone.
2. The modem manufacturer must make any repairs to the modem to
maintain valid FCC registration.
3. Notification to the telephone company is no longer required prior to
connecting registered equipment, but upon request from the telephone
company, the user shall tell the telephone company which line the
equipment is connected to as well as the registration number and ringer
equivalence number of the registered protective circuitry. FCC
information is printed on a label on the bottom of the modem.
IC (Industry Canada) Notice
Notice: The Industry Canada (formerly Canadian Department of
Communications) label identifies certified equipment. This certification means
that the equipment meets certain telecommunications network protective,
operational, and safety requirements. The department does not guarantee the
equipment will operate to the user’s satisfaction.
Before installing this equipment, users should ensure that it is permissible to be
connected to the facilities of the local telecommunications company. The
equipment must also be installed using an acceptable method of connection. In
some cases, the company’s inside wiring associated with a single-line individual
service may be extended by means of a certified connector assembly (telephone
extension cord). The customer should be aware that compliance with the above
conditions may not prevent degradation of service in some situations.
Repairs to certified equipment should be made by an authorized Canadian
maintenance facility designated by the supplier. Any repairs or alterations made
by the user may give the telecommunications company cause to request the user
to disconnect the equipment. Users should ensure for their own protection that
the electrical ground connections of the power utility, telephone lines and internal
metallic water pipe system, if present, are connected together. This precaution
may be particularly important in rural areas.
CAUTION:
Users should not attempt to make such connections themselves, but
should contact the appropriate electric inspection authority, or
electrician, as appropriate.
