Abstract

A module and kit for coupling at least one telephone service signal to at least one telephone device over a wiring. The network includes: a wiring having at least two conductors for carrying multiple time-domain multiplexed digitized voice channels; an exchange side device coupled to the wiring and operative to couple at least one telephone service signal to at least one digitized voice channel; and at least one subscriber side device coupled to the wiring and operative to couple the at least one telephone device to at least one digitized voice channel.

Claims

1. A telephone system providing a terminal for a telephone service, for use with a local area network in a building comprising local area network wiring connected for carrying at least one digitized voice channel, the system comprising:

a connector for connecting to the local area network wiring;

a local area network transceiver coupled to the connector and operative to effect point-to-point communication with a single mating transceiver over the local area network wiring in the building;

a telephone set for initiating and terminating telephone calls with the telephone service; and

a converter coupled between said telephone set and said local area network transceiver for converting between said at least one digitized voice channel and analog voice signals.

2. The system according to claim 1, wherein the local area network wiring is existing wiring in walls of the building and said system is operative to communicate with another system that is interchangeable with said system in the building over the wiring.

3. The system according to claim 1, wherein the wiring is connected to concurrently carry another distinct signal.

4. The system according to claim 3, wherein the wiring is a telephone wiring.

5. The system according to claim 1, wherein the wiring further carry data signals, and said system further comprises a data connector operative to couple the data signals to a data unit.
