What Are th e R equirements for Telephone S ervi ce?

What Are the Requirem ents for Telephone S ervice?

This section provides hardware and software requirements for using your cable
modem for telephone service.

Num ber of T elephone 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 t he tota l Ringing Load of the telephone devices tha t 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.

T elephone Device Types

You can use telephone devices that a re not labeled with a REN number, bu t 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 connect ors 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.

T el ephone W iri ng Requi rem ent s

The cable modem supports interior telephone wiring. The maximum distance from
the unit to the most distant telephone device must not exceed 1 000 feet (300 meters).
Use 26-gauge twisted-pa ir, or la rger, telephone wiring.

Important: Connection to an existing or a new perma nently installed home
telephone wiring network must be done by a qualified installer.
