Abstract

Abstract This invention is an interface arrangement which interconnects a business communication system with a telephone station set. This interface is implemented in a personal computer (PC51) which services to control the operation of the associated telephone station set (T51) and also provide business communication services. All signaling from the business communication system is received by the personal computer (PC51), interpreted, and appropriate control signals are then forwarded under control of the software (210) resident on the personal computer (PC51) to activate the digital telephone station set (T51). The signals from the digital telephone station set (T51) are intercepted by the personal computer (PC51), interpreted, modified and appropriate control messages and signaling are then forwarded by the personal computer (PC51) to the business communication system. This arrangement enables a user to create software on the personal computer (PC51) to control the operation of the telephone station set (T51) associated with the personal computer (PC51). The user can implement new features and services independent of the operation of the business communication system.

Claims Analysis

Total Claims: 11
Claim 1
Independent Claim 123 words
Interface apparatus for use with a communication system having a plurality of port circuits (111-158), each of which is connected to a corresponding one of a plurality of terminal devices (T11-T58), CHARACTERISED IN THAT said apparatus comprises processing means (PC51); connecting means (200) interposed between said one terminal device (T51), its corresponding port circuit (151) and also connected to said processing means (PC51) for connecting said processing means (PC51) to both said port circuit (151) and said terminal device (T51); and In that said processing means (PC51) comprises means responsive to communication signals from said port circuit (151) or said terminal device (T51) for interpreting said communication signals and transmitting a response message to said port circuit (151) or terminal device (T51) respectively.
Claim 2
Dependent Claim 123 words
Interface apparatus for use with a communication system having a plurality of port circuits (111-158), each of which is connected to a corresponding one of a plurality of terminal devices (T11-T58), CHARACTERISED IN THAT said apparatus comprises processing means (PC51); connecting means (200) interposed between said one terminal device (T51), its corresponding port circuit (151) and also connected to said processing means (PC51) for connecting said processing means (PC51) to both said port circuit (151) and said terminal device (T51); and In that said processing means (PC51) comprises means responsive to communication signals from said port circuit (151) or said terminal device (T51) for interpreting said communication signals and transmitting a response message to said port circuit (151) or terminal device (T51) respectively.
Claim 3
Dependent Claim 45 words
The apparatus of claim 1, CHARACTERISED IN THAT the processing means comprises means responsive to voice communication signal received from said port circuit on said terminal device for transmitting said voice communication signals as originally received to said terminal device or said port circuit respectively.
Claim 4
Dependent Claim 45 words
The apparatus of claim 1, CHARACTERISED IN THAT the processing means comprises means responsive to terminal device signaling communication signals received from said port circuit for forwarding control signals to said terminal device to perform the signaling function corresponding to said terminal device communication signals.
Claim 5
Dependent Claim 44 words
The apparatus of claim 3, CHARACTERISED IN THAT the processing means further comprises means responsive to said terminal device signaling communication signals for writing a control message corresponding to said terminal device signaling communication signals on a video monitor associated with said processing means.
Claim 6
Dependent Claim 43 words
The apparatus of claim 3, CHARACTERISED IN THAT the processing means further comprises means responsive to said terminal device signaling communication signals for transmitting a response set ofcontrol communication signals to said port circuit indicating receipt of said terminal device signaling communication signals.
Claim 7
Dependent Claim 34 words
The apparatus of claim 1, CHARACTERISED IN THAT the processing means comprises means responsive to service request control signals received from said terminal device for forwarding service request communication signals to said port circuit.
Claim 8
Dependent Claim 42 words
The apparatus of claim 6, CHARACTERISED IN THAT the processing means further comprises means responsive to said service request control signals for writing a control message corresponding to said service request control signals on a video monitor associated with said processing means.
Claim 9
Dependent Claim 41 words
The apparatus of claim 1, CHARACTERISED IN THAT the processing means comprises means responsive to the entry of a called party identification number on the keyboard of said processing means for forwarding off-hook service request communication signals to said port circuit.
Claim 10
Dependent Claim 36 words
The apparatus of claim 8, CHARACTERISED IN THAT the connecting means comprises means responsive to said called party identification number for applying tone dialing signals corresponding to said called party identification number to said port circuit.
Claim 11
Dependent Claim 56 words
The apparatus of claim 1, CHARACTERISED IN THAT the connecting means comprises means for detecting the transmission of call progress tone signals from said port circuit to said terminal device; and means responsive to said detected call progress tone signals for writing a control message identifying said detected call progress tone signals into said processing means.
