  • TMP 47C96 intelligent microprocessor
  • the RU is operated via user inputs from the control unit (CU) which is plugged into the RU via a small stereo socket.
  • the CU control line is input into the TC35301AP dual tone multi-frequency (DTMF) decoder circuit 40 which interprets the tone signals from the CU DTMF generator 51 (refer Fig. 5).
  • the DTMF decoder 40 signals to the microprocessor 41 and the appropriate responses are generated to perform the function as indicated by the user.
  • the local/remote circuit 42 which is also connected to the CU control line, detects whether the DTMF tone had been generated locally (CU connected to RU) , or remotely via the line in audio.
  • the audio-in circuit 43 mixes the three audio input signals, line-in (Aux-1), control unit mic. and handset mic. (Aux-3) as required by microprocessor 41 by means of electronic audio switches (e.g. CMOS 4066). That signal is then applied to the 7137 auto gain control circuit (AGC) 44.
  • AGC auto gain control circuit
  • the AGC signal is muted when the RU is recording a message.
  • the output from AGC circuit 44 can be switched to the play/record head circuit 45 when a message is required to be recorded on the microcassette, i.e. memo, conversation or message record.
  • the play/record circuit also acts as an output to either the monitor (Aux-4) or line-out (Aux-2) during playback of messages.
  • the output of voice recorded (VRW) circuit 46 which incorporates an NEC 7756 chip is mixed to the AGC signal.
  • the VRW chip has a pre-masked vocabulary which is controlled by microprocessor 41.
  • Microprocessor 41 will combine the necessary VRWs to form the correct phrases and then output the audio signal onto either the line-out (Aux-2) or the handset/baseset speaker monitor (Aux-4) as required. It is possible to mute the monitor line via amp mute circuit 47.
  • the out-going message circuit (OGM) 48 is also mixed with the output of the AGC. When required, (by pressing the OGM button or by receiving an incoming call) OGM circuit 48 will output the digitally stored message to both the monitor and line-out.
  • VOX circuit 49 will provide a logic signal to microprocessor 41 which indicates the presence of an input signal above a certain threshold level. If the VOX signal is not active for more than a predetermined period (e.g. 10 seconds) during a message recording microprocessor 41 will terminate that recording.
  • a predetermined period e.g. 10 seconds
  • the control unit is the principal means of operating the answering system, either in the local mode or in the remote mode.
  • the CU incorporates a standard membrane style telephone keypad 50, a DTMF generator 51, microphone 52, LED status indicator 53, mini speaker 54 and 3 volt battery 55 for use in the remote mode (the CU is powered from the RU when in the local mode) .
  • the microphone 52 is used for recording of OGM and dictation/memo messages. This signal is input into the RU AGC via circuit 44 of Fig. 5. This is the case only for local operation.
  • the keypad 50 is used to control the RU by means of DTMF signals generated by the M761A DTMF generator 51. If the CU is being operated in the local mode the DTMF signals will be sent to the AGC circuitry of the RU, but if operated in the remote mode they will be sent to the CU mini speaker 54 for transmission along the normal telephone system.
  • the red LED status indicator 53 is used to provide a visual indication of the status of the answering machine, e.g. recording mode, ready mode, answering mode, playback mode, etc.
