Abstract

A telephone message system overcomes the problems and limitations of presently available systems that seek to enhance inter-and intra-premises communications. The system advantageously comprises a controller unit with Caller ID capabilities and one or more adjunct units that are bridged onto a single wire-pair at a user'"'"'s residential location in a parallel electrical connection. These customer installable units are merely plugged into any telephone jack and share a telephone wire-pair with existing telephone extensions without interference. Such operation is possible since communication between the controller unit and the adjunct units is limited to a frequency band different from the audio frequency band used by the existing telephone extensions on the single wire-pair. The controller unit, in one configuration, operates as an answering machine with multiple mailboxes. This functionality is advantageously combined with Caller ID, intercom and speakerphone capabilities. The adjunct units may be added to any of existing telephone devices thereby providing access to the functions available at the controller unit throughout the premises.

a plurality of adjunct units operatively responsive to the controller means, each one of the plurality of adjunct units being commonly connected onto said wire-pair and communicating with said controller means over said wire-pair in a second frequency band different from said first frequency band; and

means in at least one of said adjunct units for providing said special service treatment to be given to said calls received from said preselected calling station.

2. The telephone message system as in claim 1 wherein command signals from said controller means to said adjunct units are provided over said wire-pair in said second frequency band.

3. The telephone message system as in claim 2 wherein command signals from said adjunct units to said controller means are provided over said wire-pair in said second frequency band.

4. The telephone message system as in claim 3 further including means in both the controller means and the adjunct units for frequency multiplexing and demultiplexing voice frequency signals for communicating said voice frequency signals between the controller means and the adjunct units over said second frequency band.

5. The telephone message system as in claim 3 wherein said first frequency band is in the audible frequency range.

6. The telephone message system as in claim 5 wherein said first frequency band is below 4 KHz.

7. The telephone message system as in claim 5 wherein said second frequency band is located entirely above the audible frequency range.

8. The telephone message system as in claim 7 wherein said second frequency band is above 4 KHz.

9. The telephone message system as in claim 1 wherein said assigning means further includes means for announcing in the at least one of said adjunct units the name of a calling party associated with said preselected calling station.

10. The telephone message system as in claim 9 wherein said assigning means further includes means for announcing in each of said adjunct units the name of said calling party associated with said preselected calling station.

11. The telephone message system as in claim 1 wherein said assigning means further includes means for announcing in the at least one of said adjunct units the name of said called party associated with said mailbox.

12. The telephone message system as in claim 11 wherein said assigning means further includes means for announcing in each of said adjunct units the name of said called party associated with said mailbox.

13. The telephone message system as in claim 1 wherein said controller means includes means for displaying the identity of said preselected calling station at a video display device.

14. The telephone message system as in claim 13 wherein the identity of said preselected calling station further includes displaying a name of a calling person associated with the preselected calling station.

15. A telephone message system for use at a subscriber'"'"'s premises, adapted to be parallel connected onto a wire-pair that extends between said premise and a telephone line switching system, the message system comprising:

controller means connected onto said wire-pair for receiving the identity of a preselected calling station over said wire-pair in a first frequency band, said controller means including memory means for storing the identity of the preselected calling station and an indication of a special service treatment to be given to calls received from said preselected calling station;

a plurality of adjunct units operatively responsive to the controller means, each one of the plurality of adjunct units being commonly connected onto said wire-pair and includes means for selectively connecting a telephone device operable in said first frequency band to said wire-pair, and each one of the plurality of adjunct units communicating with said controller means over said wire-pair in a second frequency band different from said first frequency band; and

means in at least one of said adjunct units for providing said special service treatment to be given to said calls received from said preselected calling station.

16. The telephone message system as in claim 15 wherein said special service treatment providing means includes means for providing a ringing signal in said telephone device attached to the at least one adjunct unit in response to receiving the identity of a preselected calling station over said wire-pair.

17. The telephone message system as in claim 15 wherein the identity of said preselected calling station is obtained through caller identification information provided over the wire-pair and associated with an incoming telephone call appearing on the wire-pair.

18. The telephone message system as in claim 17 wherein in the absence of receiving the identity of said preselected calling station, said incoming telephone call is routed to an answering machine.

19. The telephone message system as in claim 18 wherein said adjunct units further include means for providing a message indication when messages are stored in said answering machine.

20. A method of processing telephone calls in a message system arranged for use at a subscriber'"'"'s premises, the message system being adapted to be parallel connected onto a wire-pair that extends between said premises and a telephone line switching system, the method comprising the steps of:

storing the identity of a preselected calling station and an indication of a special service treatment to be given to calls received from said preselected calling station, wherein said special service treatment includes the step of assigning said calls from the preselected calling station to a mailbox of a specific called party from among multiple mailboxes respectively associated with parties commonly located at said subscriber premises;

receiving in a controller the identity of a preselected calling station over said wire-pair in a first frequency band;

commonly connecting a plurality of adjunct units onto the wire-pair, each one of the plurality of adjunct units being operatively responsive to the controller and communicating with the controller over the wire-pair in a second frequency band, said second frequency band being different from said first frequency band; and
