Abstract

A communication system comprised of a computer system connected to a local area network (LAN), a local area communications system (LAX) connected to the LAN including plural line circuits, plural telephones connected to the LAX via the line circuits, one of which is associated with the computer system, control apparatus in the computer for sending messages to the LAX via the LAN for controlling the telephone associated with the computer system, an auxiliary keyboard associated with the one telephone associated with the computer system, connected to the computer system for commanding the control apparatus to send messages to the LAX to control the one telephone.

Claims

1. A communication system comprising:

(a) a computer system connected to a local area network (LAN),

(b) a local area communications system (LAX) connected to the LAN including plural line circuits,

(c) plural telephones connected to the LAX via the line circuits, one of which is associated with the computer system,

(d) control means in the computer system for sending messages to the LAX via the LAN for controlling the telephone associated with the computer system, and

(e) an auxiliary keyboard associated with said one telephone associated with the computer system, connected to the computer system for commanding said control means to send messages to the LAX to control said one telephone.

2. A communication system as defined in claim 1 in which a map of keys of the auxiliary keyboard to commands for commanding said control means is stored in a database record.

3. A communication system as defined in claim 2 in which the database record is stored in a memory of the computer system.

4. A communication system as defined in claim 2, further including a user agent means in communication with the computer system via the LAN, the database record being stored in a memory accessible by the user agent.

5. A communication system as defined in claim 2, including a macro for commanding said control means to send messages to the LAX to control said one telephone mapped to a key, said macro being stored in said database record.

6. A communication system as defined in claim 5, in which the macro is a set of messages instructing the LAX to dial a first telephone number to place a call, send a recorded announcement to a called telephone associated with the first telephone number when a party designated by the first telephone number has answered the call, place an answered line associated with the called telephone on hold, dial a second telephone number to place a second call, send a recorded announcement to a called telephone associated with the second telephone number when a party designated by the second telephone number has answered the latter call, place an answered line associated with the latter called telephone on hold, connect a line associated with said one telephone to said lines on hold and remove the said lines from hold, thereby establishing a conference call.

7. A communication system as defined in claim 5, including a display controlled by the computer system for displaying a telephone having special feature buttons as a graphical user interface to a user of said one telephone, and for displaying as icons a library of special features on the display, the computer system comprising control means for storing macros in the database record in association with said special feature buttons for invoking features, upon dragging said icons over said special feature buttons, whereby at least one of said macros can be sent to the LAX for controlling the provision of special features upon selection of a special feature button.

8. A communication system as defined in claim 2 in which the database record is stored in a memory of the LAX.

9. A communication system as defined in claim 8, in which the computer system is contained in and forms part of the LAX, the LAN being comprised of simple conductors.

10. A communication system as defined in claim 9, including a display associated with the auxiliary keyboard for receiving commands from the computer system and displaying a telephone having special feature buttons as a graphical user interface to a user of said one telephone.

11. A communication system as defined in claim 9, in which said one telephone is connected to the LAX via an asynchronous transfer mode (ATM) network.

12. A communication system as defined in claim 9, in which said one telephone is connected to the LAX via a high speed network.

13. A communication system as defined in claim 1, the LAX including means for accepting telephone supervisory commands directly from said one telephone set in the event of inoperability of said control means in the computer system.

14. A communication system as defined in claim 13, in which the LAX includes an intercom control circuit, an intercom circuit including a loudspeaker associated with the auxiliary keyboard controllable by the intercom control circuit, whereby the LAX can control the intercom circuit by the intercom control circuit in the event of inoperability of said control means in the computer system.

15. A communication system as defined in claim 1, the LAX including means for monitoring telephone supervisory commands from said one telephone and for sending related commands to said computer system, whereby said control means, after receiving said related commands, can act to send said messages to the LAX.

16. A communication system as defined in claim 15, in which the LAX includes a handsfree control circuit, a handsfree circuit including a loudspeaker associated with the auxiliary keyboard controllable by the handsfree control circuit whereby the LAX can control the handsfree circuit by the intercom control circuit under control of said control means in the computer system.

17. A communication system as defined in claim 1, including a display associated with the auxiliary keyboard for receiving commands from the computer system and displaying a telephone having special feature buttons as a graphical user interface to a user of said one telephone.

18. A communication system as defined in claim 1, in which the LAN is comprised of an asynchronous transfer mode (ATM) network.

19. A communication system as defined in claim 18, in which the LAX is comprised of a first computer, and said one telephone is connected to the first computer via a private branch exchange (PBX).

20. A communication system as defined in claim 1, further including an adaptive communication (CATA) server connected to the LAN, the database record being stored in a memory of the CATA server associated with an agent of a user of said one telephone.
