Abstract

A combined power and communication delivery system for installation at or beyond the demarcation point in a residential or business building is described. The system has a power input module and a plurality of traditional voice and data communication wires, one pair of the wires being an unused voice or data communication line and being connected to the power input module thereby making the one pair a current-carrying line, and the plurality of wires terminating at at least one female multi-wire telephone jack. The system further having at least one power-communication cable, having a first end being a male multi-wire plug to releasably engage the female multi-wire telephone jack, a second end partially depending from the first end carrying one or more voice and data communication transmission lines, and a third end partially depending from the first end to transmit current from the current-carrying line.

Claims

1. A combined power and communication delivery system, for installation anywhere between the demarcation point and at least one female multi-wire outlet telephone jack in a building, for providing power and communication data to at least one communication device, wherein said system comprises:

(a) a power input module for receiving power from an external power supply and is coupled to said telephone jack;

wherein said module comprises wire terminals for receiving a plurality of voice and data communication wires running from said demarcation point such that said wires are coupled to said at least one telephone jack via said wire terminals;

(b) among said plurality of voice and data communication wires, a pair of said wires is being unused voice and data communication wires and used as current-carrying wires;

the remaining wires of said wires are being active voice and data communication wires;

wherein said power input module for retransmitting power from said external power supply to said at least one communication device via at least one power-communication cable and said current-carrying wires running from said power input module to said telephone jack;

(c) wherein said power-communication cable comprises a first end, a second end and a third end;

wherein said first end being a male multi-wire plug to releasably engage said female multi-wire telephone jack;

wherein said third end and second end are coupled to said at least one communication device for providing said power, and said voice and data, respectively;

wherein said second end depending from said first end carrying at least one voice and data communication transmission wire for electrical communication with said active voice and data communication wires, and said third end depending from said first end to transmit current from said current-carrying wire, so that said second end is electrically connected to said active voice and data communication wires and said third end is electrically connected to said current-carrying wires.

2. A system as claimed in claim 1, wherein said power input module is stationed at or just beyond the demarcation point.

3. A system as claimed in claim 2, wherein said power input module is stationed at any point between telephone jacks.

4. A system as claimed in claim 1, wherein said power input module comprises:

(a) a power input connection to connect at one end thereof said external power supply for receiving power from said external power supply;

(b) wherein said wire terminals to connect at one end thereof said current-carrying wires;

(c) connection means for transmitting current from said input connection to said wire terminals.

5. A system as claimed in claim 4, wherein said power input module includes over-current and short circuit protection means.

6. A system as claimed in claim 5, wherein said power input module includes a removable cover, said cover when removed provides access to said wire terminals.

7. A system as claimed in claim 6, wherein said system further comprises a power cable for providing power from said external power supply to said power input module;

wherein said input connection is a female coaxial connector to receive a male coaxial plug of said power cable;

said power cable having a further end including a power plug connected to said external power supply.

8. A kit for providing combined power and telecommunication transmission over telephone wiring to at least one communication device, a plurality of voice and data communication wires are running from a demarcation point to at least one female multi-wire outlet telephone jack in the building, one pair of said wires being an unused voice and data communication wire and the remaining wires of said wires being active voice and data communication wires, said kit comprising:

(a) at least one power input module for receiving power from an external power supply, said power input module connected to said at least one female multi-wire telephone jack via a male multi-wire connection of said module such that said module is electrically connected to said wires;

wherein said module further comprises a connection means and a female multi-wire connection;

wherein said connection means electrically connects said wires to said female multi-wire connection;

wherein said pair of said wires running from said telephone jack to said module in the connection means are being current-carrying wires in said module;

wherein said power input module for retransmitting power from said external power supply to said at least one communication device via at least one power-communication cable and said current-carrying wires;

(b) wherein said at least one power-communication cable comprises a first end, a second end and a third end;

wherein said first end being a male multi-wire plug to releasably engage said female multi-wire connection of said at least one power input module;

wherein said second end and third end are coupled to said at least one communication device for providing said power, and said voice and data, respectively;

wherein said second end depending from said first end carrying at least one voice and data communication transmission wire for electrical communication with said active voice and data communication wires, and said third end depending from said first end to transmit current from said current-carrying wire, so that said second end is electrically connected to said active voice and data communication wires and said third end is electrically connected to said current-carrying wires.

9. A kit as claimed in claim 8, wherein each of said modules includes over-current and short circuit protection means.
