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 comprises a controller unit with Caller ID capabilities and one or more adjunct units that are all bridged onto a single wire-pair at a user'"'"'s residential location in a parallel electrical connection. For facilitating a message routing capability, a mailbox of groups of telephone numbers are associated with a particular party at the residence. These telephone numbers are preprogrammed into the controller unit so that upon receipt of an incoming call from one of these telephone numbers, identified through caller ID, the incoming call is associated with the particular called party and the controller unit routes the incoming call directly to the called party'"'"'s mail box where the calling party is able to leave a message. A user may easily access received messages stored in his or her mailbox in the message system which may be configured as either open or restricted. If the message system is open, then a user may access not only messages in his or her mailbox but also access messages in any of other mailboxes also in the system. If the message system is restricted, however, then a user is allowed access only to messages in his or her mailbox.

3. The message system of claim 1 wherein said adjunct unit includes means for retrieving a telephone message stored in said specific one of said plurality of mailboxes.

4. The message system of claim 3 wherein said retrieving said retrieving means includes code means enterable at said adjunct unit for retrieving the telephone message stored in said specific one of said plurality of mailboxes.

5. The message system of claim 1 wherein said controller means further includes outgoing message means responsive to receipt of the identity of one of said preselected calling stations for sending a message to said calling station, each outgoing message being indicative of a called party associated with a mailbox within the plurality of mailboxes.

6. The message system of claim 4 wherein said first frequency band is in the audible frequency range.

7. The message system of claim 6 wherein said first frequency band is below 4 KHz.

8. The message system of claim 6 wherein said second frequency band is located entirely above the audible frequency range.

9. The message system of claim 7 wherein said second frequency band is above 4 KHz.

10. The message system of claim 4 wherein said mailbox means comprises a digital answering machine.

11. A method for 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:

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

storing telephone messages in a plurality of mailboxes, each mailbox being respectively associated with a group of preselected calling stations;

routing a call from said calling station to the respectively associated mailbox within the plurality of mailboxes in response to receipt of the identity of said calling station;

connecting at least one adjunct unit onto the wire-pair, the adjunct unit being operatively responsive to the controller and communicating with said controller over said wire-pair in a second frequency band, said second frequency band being different from said first frequency band; and

interrogating in said adjunct unit at least a specific one of said plurality of mailboxes for determining when a telephone message from at least one of said preselected calling stations is stored in said specific one of said plurality of mailboxes.

12. The method of claim 11 further including the step of 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 said controller over said wire-pair in said second frequency band.

13. The method of claim 11 further including the step of retrieving in said adjunct unit a telephone message stored in said specific one of said plurality of mailboxes.

14. The method of claim 13 wherein the retrieving step includes the step of entering a preselected code at said adjunct unit for retrieving the telephone message stored in said specific one of said plurality of mailboxes.

15. The method of claim 11 further including sending an outgoing message to one of said preselected calling stations responsive to receipt of the identity of said calling station, each outgoing message being indicative of a called party associated with a mailbox within the plurality of mailboxes.

16. The method of claim 14 wherein said first frequency band is the audio frequency band.

17. The method of claim 16 wherein said first frequency band is below 4 KHz.

18. The method of claim 17 wherein said second frequency band is located entirely above the audio frequency band.

19. The method of claim 17 wherein said second frequency band is above 4 KHz.

20. The method of claim 14 wherein said plurality of mailboxes comprises a digital answering machine.

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