Abstract

An interface circuit provides a wireless channel and a line channel to a telephone set. The wireless channel is coupled to a controller (e.g. a PC) and to another telephone set, and the line channel is coupled to a telephone network. A switch circuit connects the telephone set to the wireless channel to transmit a signal between the telephone set and the controller (or another telephone set). The switch circuit connects the telephone set to the line channel to transmit a signal between the telephone set and the telephone network.

Claims

1. A telephone system for providing a telephony feature, comprising a phone system controller and a first telephone system interface, wherein:

said first telephone system interface is (a) coupled between a first telephone handset and a telephone line, and (b) operable to (i) selectively couple said first telephone handset to said telephone line, (ii) provide a wireless control channel that is operable to carry first control signals associated with said telephony feature to said phone system controller, (iii) provide a wireless communication channel that is operable to carry voice signals of said first telephone handset to said phone system controller, and (iv) couple said first telephone handset to said telephone line in response to receiving a second control signal from said phone system controller via said wireless control channel, and

said phone system controller comprises a personal computer system having telephony support, said phone system controller operable to (i) receive said first control signals via said wireless control channel and said voice signals via said wireless communication channel, (ii) process said first control signals and said voice signals to provide said telephony feature, and (iii) transfer said second control signals to said first telephony system interface via said wireless communication channel in response to processing said first control signals and said voice signals.

2. The telephone system of claim 1, wherein:

said phone system controller is coupled to said telephone line and is further operable to execute said telephony feature by applying signals to said telephone line.

3. The telephone system of claim 1, further comprising a second telephone system interface coupled between a second telephone handset and said telephone line, said second telephone system interface operable to (i) selectively couple said second telephone handset to said telephone line, and (ii) utilize said wireless control channel to carry second control signals associated with said telephony feature to said phone system controller, wherein:

said phone system controller is operable to (i) receive said second control signals via said wireless control channel, and (ii) process said second control signals to provide said telephony feature.

4. The telephone system of claim 1, further comprising a second telephone system interface coupled between a second telephone handset and said telephone line, said second telephone system interface operable to (i) selectively couple said second telephone handset to said telephone line, (ii) utilize said wireless control channel to carry second control signals associated with said telephony feature to said first telephone system interface, and (iii) provide a wireless communication channel that is operable to carry voice signals of said second telephone handset to said first telephone system interface, wherein:

said first telephone system interface is further operable to (i) receive said voice signals of said second telephone system via said wireless communication channel, and (ii) provide said voice signals to said first telephone handset.
