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 module for coupling a telephone device to at least one time-domain multiplexed digitized voice channel carried over bus topology wiring in a building, the wiring having at least two conductors, the module comprising:

a local area network modem couplable to the wiring and operative to communicate with at least one other modem over the bus topology wiring in the building;

selective means coupled to said local area network modem and operative to pass a first voice channel;

a subscriber line interface coupled to said selective means and operative to convert said first voice channel to a first analog telephone signal; and

a first telephone connector coupled to said subscriber line interface and couplable to a telephone device to couple the telephone device to said first analog telephone signal.

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

3. The module according to claim 2, wherein the wiring is used to concurrently carrying a service signal.

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

5. The module according to claim 2, wherein the module is dimensioned to be mountable in an outlet cavity in a wall.

6. The module according to claim 2, wherein the module is at least in part housed within an outlet.

7. The module according to claim 1 wherein the wiring concurrently carries a frequency domain multiplexed second analog telephone signal in a telephone band, and the module further comprises:

a frequency selective means couplable to the wiring and operative to pass the said second analog telephone signal; and

a second telephone connector coupled to said frequency selective means for coupling a telephone device to said second analog telephone signal.

8. The module according to claim 1, wherein the multiplexed digitized voice channels carry Pulse Code Modulation (PCM) signals.

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

10. A kit for use with a wiring system in a building having a continuous wire pair and multiple outlets for connecting to said wire pair and forming a bus topology, the wire pair carrying at least one time-domain multiplexed digitized voice channel, said kit comprising:

at least two modules, each as defined in claim 1, all of said modules having interchangeable modems, and each of said modems being operative to communicate with all other modems of the other modules.

11. The module according to claim 1, further comprising means for detachably electrically and mechanically coupling said module to an outlet opening in a wall.

12. A module for coupling at least one analog telephone service signal to at least one time-domain multiplexed digitized voice channel carried over a wiring having at least two conductors, for use with an analog telephone service connection for conducting the analog telephone service signal and connectable to an analog telephone set, the module comprising:

at least one exchange line interface connectable to the at least one analog telephone service connection, and operative to convert the at least one analog telephone service signal to a digitized service signal; and

a modem coupled to said at least one exchange line interface and operative to conduct said digitized service signal over the wiring.

13. The module according to claim 12, wherein the module is used for coupling multiple service signals to multiple time-domain multiplexed digitized voice channels carried over the wiring, and wherein the module further comprising selective means coupled to said modem and to said at least one exchange line interface and operative to selectively couple said multiple digitized voice channels carried over the wiring to said digitized service channels.

14. The module according to claim 12, wherein the wiring is existing wiring in the building, and said modem is operative to communicate with interchangeable modems in the building over the existing wiring.

15. The module according to claim 14, wherein the wiring is used to concurrently carrying a service signal.

16. The module according to claim 15, wherein the wiring is a telephone wiring.

17. The module according to claim 14, wherein the module is dimensioned to be mountable in an outlet cavity in a wall.

18. The module according to claim 14, wherein the module is at least in part housed within an outlet.

19. The module according to claim 12, wherein the wiring concurrently carries a frequency domain multiplexed analog telephone signal in a telephone band, and the module further comprises:

a connection means for coupling to an analog telephone service; and

a frequency selective means coupled to said connection means and couplable to the wiring, and operative to pass the analog telephone signal.

20. The module according to claim 12, wherein the multiplexed digitized voice channels carry Pulse Code Modulation (PCM) signals.

21. The module according to claim 12, wherein the wiring further carry data signals, and the module further comprises a data connector operative to couple the data signals to a data unit.

22. The module according to claim 12, wherein said modem is operative to communicate with at least one interchangeable modem over the wiring.
