  • Page 29: Auto Disconnect Circuit

    9.3. Auto Disconnect Circuit Function: This circuit is used to detect the fact that another telephone connected to the same line is OFF- HOOK while the unit is in a receiving status or OGM transmitting status. Circuit Operation: The voltage pin 35 of IC201 is monitored. If a parallel-connected telephone is put into an OFF HOOK status, the presence/absence of a parallel connection is determined when the voltage changes by 0.2V or more.

  • Page 30: Power Supply Circuit

    9.4. Power Supply Circuit Function: Power from the AC adaptor passes through a regulating block consisting of IC303. Circuit Operation: Q301 is a regulated power supply. The voltage at point A is regulated to 3.6 V by IC303. The voltage at point B is dropped by D303 and L301 to 3.3V. The voltage at point C is dropped by D304 to 3.3V.

  • Page 32 9.8. Calling Line Identification Circuit (Caller ID) Function: The caller ID is a chargeable ID which the user of a telephone circuit obtains by entering a contract with the telephone company to utilize a caller ID service. For this reason, the operation of this circuit assumes that a caller ID service contract has been entered for the circuit being used.
  • Page 33 Call Waiting Calling Identity Delivery on Call Waiting (CIDCW) is a CLASS service that allows a customer, while off-hook on an existing call, to receive information about a calling party on a waited call. The transmission of the calling information takes place almost immediately after the customer is alerted to the new call so he/she can use this information to decide whether to take the new call.
  • Page 34 9.9. Parallel Connection Detect Circuit Function: In order to disable call waiting and stutter tone functions when using telephones connected in parallel, it is necessary to have a circuit that judges whether a telephone connected in parallel is in use or not. This circuit determines whether the telephone connected in parallel is on hook or off hook by detecting changes in the T/R voltage.
  • Page 35 9.10. DSP (Digital Speech/Signal Processing) Circuit General Description: (IC201, IC300, IC306) are a digital speakerphone/speech/signal processing system that implements all the functions of speech compression, record and playback, and memory management required in a digital telephone answering machine. The DSP system is fully controlled by a host processor IC201. The host processor provides activation and control of at that functions, such as speech Recording, Playback, Tone detecting and Line momitoring.
  • Page 36 - DTMF Detection The DTMF detection is implemented by the DSP system in software. The DTMF detection is performed during Record, Playback, and Line Monitoring modes of operation. - Synthesized Voice The DSP implements synthesized Voice, utilizing the built in speech detector and an FLASH MEMORYS (IC300, IC306), which stored the vocabulary.

    voltage appears at the Tip (T) and Ring (R) leads (When the telephone rings), the AC ring voltage is transferred as follows: L101 IC201 pin 27. When the CPU (DSP) detects a ring signal, Q103 turns on, thus providing an off-hook condition (active DC current flow through the circuit) and the following signal flow is for the voice signal.
