Abstract

An interface circuit used between a telephone office and a subscriber'"'"'s telephone operated in response to signals identifying incoming calls to provide visual and/or audible indications of the identification information. The incoming signal information is also extended in decoded form to an associated computer, computer network, and/or television screen.

Claims

1. An interface circuit for use between a telephone central office and a subscriber'"'"'s telephone instrument for identifying the source of an incoming call, including control means, display means connected to said control means operated in response to signals representative of the identity of the source of said incoming call received from said telephone central office via a telephone line, to provide a visual indication of said incoming call identification, and a calling device connected to said control means operable by a subscriber to operate said control means to transmit via said telephone line, call selection signals, the improvement comprising:

a dialer circuit connected between said control means and said telephone line;

sensing means connected between said telephone line and said control means operated to indicate to said control means the condition of said telephone line;

decoder means connected between said telephone line and said control means, operated to decode incoming signals and extend decoded information representative of said incoming signals to said control means;

a loudspeaker;

recording and reproducing means connected between said loudspeaker and said control means, operated in response to said decoded information received from said control means to reproduce audibly the identification of the source of said incoming call;

a microphone connected to said recording and reproducing means, said microphone and said recording and reproducing means operated by a subscriber to program in a voice memory associated with said recording and reproducing means, information related to the identity of the source of an incoming telephone call; and

a computer interface connected between said control means and a computer, said decoded information extended via said computer interface to said computer.

2. An interface circuit as claimed in claim 1 wherein:

computer interface circuit is of the RS232 industry standard type.

3. An interface circuit as claimed in claim 1 wherein:

there is further included television display means connected between said control means and a television set operated in response to decoded information from said control means to operate a screen associated with said television set to indicate the identification of the source of said incoming call.

4. An interface circuit as claimed in claim 3 wherein:

said television display means comprises a serial interface connected to said control means, channel selection logic and controller means connected to said serial interface, said channel selection logic including connections to an on-screen display controller and to a demodulator, said demodulator connected to an external antenna to receive incoming signals for extension through a mixer and modulator to said associated television display means;

said on-screen display controller including circuit connections between said channel selection logic and said mixer and modulator.

5. An interface circuit as claimed in claim 1 wherein:

said computer interface between said computer and said control means includes an address decoder, a control register, and a data register.

6. An interface circuit as claimed in claim 1 wherein:

there is further included a voice activated speakerphone including circuit connections to said telephone line, to said control means and including a circuit connection to said recording and reproducing means;

said voice activated speakerphone programmed via said control means by said subscriber to be operable when subscriber is not directly at said subscriber'"'"'s telephone instrument, whereby in response to a receipt of audible identification of the source of said incoming call, said subscriber may converse and respond to said incoming call via said voice activated speakerphone.

7. An interface circuit as claimed in claim 1 wherein:

said computer in response to said decoded information received from said control means via said computer interface, will cause supplemental information related to the identity of the source of incoming call to be displayed.

8. An interface circuit as claimed in claim 1 wherein:

there is further included an additional memory connected to said control means;

said additional memory storing supplemental information related to the identity of the source of selected incoming calls.

9. An interface circuit as claimed in claim 8 wherein:

in response to receipt of decoded information received from said control means, said supplemental information is drawn from said additional memory;

said control means further operated in response to said supplemental information to cause said supplemental information to be reproduced audibly by said reproducing means or in the alternative to be reproduced visually by said display means.
