What Are the Requirements for Telephone Service?
What Are the Requirements for Telephone Service?
This section provides hardware and software requirements for using your cable
modem for telephone service.
Number of Telephone Devices
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.
Telephone Device Types
You can use telephone devices that are not labeled with a REN number, but the
maximum number of attached telephone devices cannot be accurately calculated.
With telephone devices that are not labeled, each device should be connected and
the ring signal should be tested before adding more devices. If too many telephone
devices are attached and the ring signal can no longer be heard, telephone devices
should be removed until the ring signal works properly.
Telephones, fax machines, and other telephone devices should use the center 2 pins
of the RJ-11 connectors to connect to the cable modem telephone ports. Some
telephones use other pins on the RJ-11 connectors and require adapters in order to
work.
Dialing Requirements
All your telephones should be set to use DTMF dialing. Pulse dialing is typically not
enabled by your local provider.
Telephone Wiring Requirements
The cable modem supports interior telephone wiring. The maximum distance from
the unit to the most distant telephone device must not exceed 1000 feet (300 meters).
Use 26-gauge twisted-pair, or larger, telephone wiring.
Important! Connection to an existing or a new permanently installed home
telephone wiring network must be done by a qualified installer.

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.

Having Difficulty?
Q. How does the cable modem connect to my computer?
A. The cable modem connects to the USB port or the 10/100BaseT Ethernet port on
your PC. If your PC is not equipped with an Ethernet interface, an Ethernet card is
available from your local PC or office supply retailer, or from your cable service
provider.
Q. After my cable modem is connected, how do I access the Internet?
A. Your local service provider becomes your Internet Service Provider (ISP). They
offer a wide range of services including e-mail, chat, news, and information services.
Your cable service provider will provide the software you will need.
Q. Can I watch TV and surf the Internet at the same time?
A. Absolutely! If you subscribe to cable television service, you can watch TV and
use your cable modem at the same time by connecting your TV and your cable
modem to the cable network using an optional cable signal splitter.
Q. Can I run more than one device on the modem?
A. Yes. A single cable modem will theoretically support up to 253 Ethernet devices
utilizing user-supplied Ethernet hubs or routers that you can purchase at your local
PC or office supply retailer. Another user at your location can simultaneously
connect to the USB port on the cable modem. Contact your service provider for
further assistance.
