Claim 3

A telephone set in accordance with claim 1 further comprising means responsive to selected ones of said command and control signals to provide a visual indication of additional manual steps to be performed to complete said selected function or completion of said function.

Claim 4

A telephone set in accordance with claim 1 wherein said means for transmitting selected ones of said command and control signals comprises means for generating tone signals in response to selected ones of said command and control signals.

Claim 5

A telephone set in accordance with claim 1 wherein the confirmation and control signals transmitted by the switching system are coded tone signals and said means for receiving said confirmation and control signals comprises a plurality of tone decoders.

Claim 6

A telephone set in accordance with claim 4 wherein the telephone has means for transmitting voice communications including an audio receiver and further comprising means for disabling said audio receiver while said confirmation and control signals are being received by said telephone set.

Claim 7

A telephone set for use in a telephone communication network having a switch gear connected to incoming lines and to a plurality of terminal stations each terminal station connected to a wire pair over which audio signals are transmitted, the switch gear having means for selectively establishing communication between selected terminal stations and incoming lines, means for receiving command signals from the telephone stations corresponding to a selected function, means for generating a coded confirmation signal and transmitting the confirmation signal to the telephone stations in response to the command signals, and means for performing the function dictated by command signals, comprising: (a) a plurality of manually actuated switches, each switch associated with a particular function; (b) a microprocessor, said microprocessor having means for automatically scanning said switches and generating a plurality of first output signals in a pre-determined sequence corresponding to a selected function; (c) a tone generator connected to said microprocessor for generating a coded tone command signal in response to selected ones of said first output signals for transmission of the switch gear over the wire pair over which audio signals are transmitted; (d) a plurality of tone detectors each detector tuned to a pre-selected response frequency and having an input connected to the two-wire audio communications lines and an output connected to said microprocessor, said tone detectors generating a second output signal on said output thereof in response to detection of a confirmation signal having the pre-selected frequency of said tone detector; and (e) a plurality of visual indicators, each of said visual indicators connected to an output of said microprocessor, said microprocessor having means for automatically applying excitation signals to said visual indicators corresponding to said second output signals thereby providing a visual indication of additional manual steps to be performed to complete said selected function or completion of said function.

Claim 8

A telephone set for use in a telephone communication network having a switch gear connected to incoming lines and to a plurality of terminal stations each terminal station connected to a wire pair over which audio signals are transmitted, the switch gear having means for selectively establishing communication between selected terminal stations and incoming lines, means for receiving command signals from the telephone stations corresponding to a selected function, means for generating a coded confirmation signal and transmitting the confirmation signal to the telephone stations in response to the command signals, and means for performing the function dictated by command signals, comprising: (a) a plurality of manually actuated switches, each switch associated with a particular function; (b) a microprocessor, said microprocessor having means for automatically scanning said switches and generating a plurality of first output signals in a pre-determined sequence corresponding to a selected function; (c) a tone generator connected to said microprocessor for generating a coded tone command signal in response to selected ones of said first output signals for transmission of the switch gear over the wire pair over which audio signals are transmitted; (d) a plurality of tone detectors each detector tuned to a pre-selected response frequency and having an input connected to the two-wire audio communications lines and an output connected to said microprocessor, said tone detectors generating a second output signal on said output thereof in response to detection of a confirmation signal having the pre-selected frequency of said tone detector; and (e) a plurality of visual indicators, each of said visual indicators connected to an output of said microprocessor, said microprocessor having means for automatically applying excitation signals to said visual indicators corresponding to said second output signals thereby providing a visual indication of additional manual steps to be performed to complete said selected function or completion of said function.

Claim 9

A telephone set in accordance with claim 6 comprising: (a) means for transmitting and receiving voice communications; and (b) means connected to said microprocessor and responsive to disabling signals therefrom for disabling said voice receiving and transmitting means during receipt of coded confirmation signals from the switch gear.
