Abstract

Abstract A message telephone with message recording and reproducing function equipped with remote control switch is disclosed. The message telephone has a calling signal identification circuit and after counting a predetermined number of calling signals, if the calling party once disconnects the call and orginates a second call within a predetermined time interval the device works as a message telephone after providing an identifying MF signal pass-word to work various message functions under control of the remote calling party.

Claims Analysis

Total Claims: 11
Claim 1
Independent Claim 194 words
A telephone message device having remote control switching capabilities comprising: calling signal identification circuit means for identifying the number of calling signals transmitted to said device that are generated from another telephone; MF signal password identification circuit means for identifying various passwords; means for recording and reproducing a message from a calling party; message function means for access by a calling party; and at least one micro-computer having a plurality of switching circuits under the control of said micro-computer, said switching circuits interconnecting said calling signal circuit means, said MF signal password circuit means, said means for recording and reproducing and said message function means in a predetermined way so that after a calling party disconnects a calling signal connection after counting a predetermined number n 1 of calling signals, said device is switching into a recording function stand-by mode, and upon receiving an additional calling signal within a predetermined time interval t 1 , said means for recording and reproducing and said message function means are actuable by a calling party after said device identifies a password signal, provided by a calling party, by means of said MF signal password identification circuit means.
Claim 2
Dependent Claim 194 words
A telephone message device having remote control switching capabilities comprising: calling signal identification circuit means for identifying the number of calling signals transmitted to said device that are generated from another telephone; MF signal password identification circuit means for identifying various passwords; means for recording and reproducing a message from a calling party; message function means for access by a calling party; and at least one micro-computer having a plurality of switching circuits under the control of said micro-computer, said switching circuits interconnecting said calling signal circuit means, said MF signal password circuit means, said means for recording and reproducing and said message function means in a predetermined way so that after a calling party disconnects a calling signal connection after counting a predetermined number n 1 of calling signals, said device is switching into a recording function stand-by mode, and upon receiving an additional calling signal within a predetermined time interval t 1 , said means for recording and reproducing and said message function means are actuable by a calling party after said device identifies a password signal, provided by a calling party, by means of said MF signal password identification circuit means.
Claim 3
Dependent Claim 37 words
The telephone message device as defined in claim 1 including means for preventing the bell of a telephone in communication with said device from ringing during the counting of said predetermined number n 1 of calling signals.
Claim 4
Dependent Claim 22 words
The telephone message device as defined in claim 1, wherein said message function means include message transmission means and message recording means.
Claim 5
Dependent Claim 19 words
The telephone message device as defined in claim 1, wherein said predetermined number n 1 is 1 to 10.
Claim 6
Dependent Claim 21 words
The telephone message device as defined in claim 1, wherein said predetermined time interval t 1 is 1 to 60 seconds.
Claim 7
Dependent Claim 23 words
The telephone message device as defined in claim 1, wherein said message function means include erase signal receiving means and message erase means.
Claim 8
Dependent Claim 27 words
The telephone message device as defined in claim 1, wherein said message function means include a plurality of individual channels, each channel providing a separate message function.
Claim 9
Dependent Claim 21 words
The telephone message device as defined in claim 1, wherein said switching circuits are separate from said at least one micro-computer.
Claim 10
Independent Claim 209 words
A method of enabling a calling party to receive and provide a separate private message from another telephone having a telephone message device equipped with remote control switching capabilities comprising the steps of: providing calling signal identification circuit means for identifying the number of calling signals transmitted to said device that are generated from another telephone; providing MF signal password identification circuit means for identifying various passwords; providing means for recording and reproducing a message from a calling party; providing message functions means for access by a calling party; providing a plurality of switching circuits interconnecting said calling signal circuit means, said MF signal password circuit means, said means for recording and reproducing and said message function means in a desired way; providing a micro-computer for controlling said switching circuits; providing a predetermined number n 1 of calling signals to said device; disconnecting the connection providing said calling signals after achieving said predetermined number n 1 of calling signals; switching said device into a recording function stand-by mode; providing a calling signal to said device within a predetermined time interval t 1 ; entering a password; identifying said password by said MF signal password identification circuit means; and enabling access to said message function means by a calling party.
Claim 11
Independent Claim 209 words
A method of enabling a calling party to receive and provide a separate private message from another telephone having a telephone message device equipped with remote control switching capabilities comprising the steps of: providing calling signal identification circuit means for identifying the number of calling signals transmitted to said device that are generated from another telephone; providing MF signal password identification circuit means for identifying various passwords; providing means for recording and reproducing a message from a calling party; providing message functions means for access by a calling party; providing a plurality of switching circuits interconnecting said calling signal circuit means, said MF signal password circuit means, said means for recording and reproducing and said message function means in a desired way; providing a micro-computer for controlling said switching circuits; providing a predetermined number n 1 of calling signals to said device; disconnecting the connection providing said calling signals after achieving said predetermined number n 1 of calling signals; switching said device into a recording function stand-by mode; providing a calling signal to said device within a predetermined time interval t 1 ; entering a password; identifying said password by said MF signal password identification circuit means; and enabling access to said message function means by a calling party.
