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 network for coupling each of a first bi-directional serial digital data stream and a second bi-directional serial digital data stream external to a building to respective ones of first and second units in the building, said network comprising:

first wiring comprising two conductors at least in part in walls of the building and at least in part external to the building, said first wiring being connected to carry the first and second bi-directional serial digital data streams in time multiplexed form;

second wiring comprising two conductors at least in part in walls of the building, said second wiring being connected to carry the second bi-directional serial digital data stream;

a first outlet connected to said first wiring, said first outlet being mounted in a wall opening or an outlet opening;

a second outlet connected to said second wiring, said second outlet being mounted in a wall opening or an outlet opening;

a first device couplable to the first unit, said first device being connected to said first outlet for connection to said first wiring and being connected to said second wiring, said first device being operative to couple the first bi-directional serial digital data stream to the first unit and to pass the second bi-directional serial digital data stream between said first and second wirings; and

a second device couplable to the second unit, said second device being connected to said second outlet for connection to said second wiring, said second device being operative to couple the second bi-directional serial digital data stream to the second unit.

2. The network according to claim 1 wherein said first device is attached to said first outlet.

3. The network according to claim 1 wherein said second device is attached to said second outlet.

4. The network according to claim 1 wherein said first wiring is communicatively coupled to distinct first and second service providers respectively for the first and second bi-directional serial digital data streams.

5. The network according to claim 4 wherein at least one of the service providers is a telephone network operator, and said first wiring is coupled to a telephone network.

6. The network according to claim 4 wherein at least one of the service providers is a non-telephone network operator.

7. The network according to claim 6 wherein the non-telephone network operator is a CATV network operator.

8. The network according to claim 1 wherein said first wiring is a telephone wire pair and said first outlet is a telephone outlet.

9. The network according to claim 1 wherein said first wiring is connected to further simultaneously carries a service signal using frequency domain multiplexing.

10. The network according to claim 9 wherein the service signal is an analog telephone signal and said first outlet is a telephone outlet.

11. The network according to claim 10 wherein said first and second serial digital data streams are carried over said first wiring using DSL.

12. The network according to claim 1 wherein said second wiring is connected to further simultaneously carries a service signal using frequency domain multiplexing.

13. The network according to claim 12 wherein the service signal is an analog telephone signal and said second outlet is a telephone outlet.

14. The network according to claim 1 wherein the building is a residence, an office, or a factory.

15. The network according to claim 1 wherein the first bi-directional serial digital data stream carries digitized telephony data and wherein the first unit is a telephone set connected to be coupled to the digitized telephony data.

16. The network according to claim 1 wherein the second bi-directional serial digital data stream carries digitized telephony data and wherein the second unit is a telephone set connected to be coupled to the digitized telephony data.

17. The network according to claim 1 wherein the first and second bi-directional serial digital data streams respectively carry first and second digitized telephony data and wherein the first and second units are respectively first and second telephone sets respectively connected to be coupled to the first and second digitized telephony data.

18. The network according to claim 17 further operative to support exchange/PBX-type features between the first and second telephone sets.

19. The network according to claim 18 wherein the exchange/PBX features are one or more of:

hold/call pick-up;

call transfer;

conference call;

intercom;

ringing all;

repertory dialing; and

memory dialing.

20. The network according to claim 17 wherein the exchange/PBX features include an intercom function, and wherein a telephone session can be executed between the first and second telephone sets.

21. The network according to claim 1 wherein said first and second devices are connected in a point-to-point connection over said second wiring.

22. The network according to claim 1 wherein one or each of said devices is integrated into said outlet connected thereto.
