Abstract

The invention relates to a receiver stage in a telephony device which receiver stage permits of receiving and decoding coded signals distinct from the speech signals to route them to a memory area. This solution permits of a simple and automatic information transfer from the called party to the memory of the user'"'"'s telephony device.

Claims

1. A telephone device comprising:

an input receiver which receives an input signal from a remote terminal, said input signal including a speech signal and a data signal;

a data receiver which is selectively connected to said input receiver to automatically receive said data signal;

a housing which contains said input receiver and said data receiver; and

a switch which disconnects said data receiver from said input receiver in response to a control signal;

said control signal being provided by an input key of said telephone device or by said input signal.

2. The telephone device of claim 1, wherein said data receiver includes a decoder and a memory, said decoder decoding said data signal and providing a decoded data to said memory which stores said decoded data.

3. The telephone device of claim 1, wherein said data receiver includes a decoder, a memory, and a processor, said decoder decoding said data signal and providing a decoded data to said processor for processing said decoded data and storing said decoded data in said memory.

4. The telephone device of claim 1, wherein said speech signal is a digital signal contained in frames which are distinct from frames containing said data signal.

5. The telephone device of claim 1, wherein said data signal is a DTMF signal multiplexed with said speech signal.

6. A communication system comprising:

a plurality of telephone devices;

a central switching device for establishing communication between at least two of said plurality of telephone devices;

wherein one of said plurality of telephone devices includes;

an input receiver which receives an input signal from another of said plurality of telephone devices, said input signal including a speech signal and a data signal;

a data receiver which is selectively connected to said input receiver to automatically receive said data signal;

a housing which contains said input receiver and said data receiver; and

a switch which disconnects said data receiver from said input receiver in response to a control signal;

said control signal being provided by an input key of said telephone device or by said input signal.

7. The communication system of claim 6, wherein said data receiver includes a decoder and a memory, said decoder decoding said data signal and providing a decoded data to said memory which stores said decoded data.

8. The communication system of claim 6, wherein said data receiver includes a decoder, a memory, and a processor, said decoder decoding said data signal and providing a decoded data to said processor for processing said decoded data and storing said decoded data in said memory.

9. The communication system of claim 6, wherein said speech signal is a digital signal contained in frames which are distinct from frames containing said data signal.

10. The communication system of claim 6, wherein said data signal is a DTMF signal multiplexed with said speech signal.

11. A telephone device comprising:

an input receiver which receives an input signal from a remote terminal, said input signal including a speech signal and a data signal;

a data receiver which is selectively connected to said input receiver to automatically receive said data signal while said input receiver is receiving said speech signal;

a housing which contains said input receiver and said data receiver; and

a switch which disconnects said data receiver from said input receiver in response to a control signal.

12. The telephone device of claim 11, further comprising an input key which provides said control signal.

13. The telephone device of claim 11, wherein said control signal is provided by said input signal.

14. A wireless telephone comprising:

an input receiver which receives said input signal from a remote terminal, said input signal providing communication between said telephone and said remote terminal;

a first amplifier which amplifies said input signal to form an amplified signal;

a filter which filters said amplified signal to form a filtered signal;

a second amplifier having an amplifier input which receives said filtered signal, said second amplifier amplifying said filtered signal to form an output signal;

a data receiver which is selectively connected to said amplifier input to automatically receive said data signal during said communication; and

a switch which disconnects said data receiver from said amplifier input in response to a control signal.

15. The wireless telephone of claim 14, further comprising an input key which provides said control signal.

16. The wireless telephone of claim 14, wherein said control signal is provided by said input signal.

17. The wireless telephone of claim 14, further comprising a housing which contains said input receiver and said data receiver.
