    KX-TG3611BX/KX-TG3612BX/KX-TGA361BX 4.5. Circuit Operation (Base Unit) General Description: (DSP, EEPROM) is a digital speech/signal processing system that implements all the functions of speech compression. The DSP system is fully controlled by a host processor DSP. The host processor provides activation and control of all that func- tions as follows.
  • Page 14 KX-TG3611BX/KX-TG3612BX/KX-TGA361BX 4.5.3. Power Supply Circuit Function: The power supply voltage from AC adaptor is converted to the desired voltage of each block. Circuit Operation: • IC332: 3.3 V Regulator • IC331: 3.0 V Regulator...
  • Page 15 KX-TG3611BX/KX-TG3612BX/KX-TGA361BX 4.5.3.1. Charge Circuit The voltage from the AC adaptor is supplied to the charge circuits.
  • Page 16 KX-TG3611BX/KX-TG3612BX/KX-TGA361BX 4.5.4. Reset Circuit Function: This circuit is used to initialize the microcomputer when it incorporates an AC adaptor. Circuit Operation: When the AC Adaptor is inserted into the unit, then the voltage is shifted by IC331 and power is supplied to the DSP. The set starts to operate when VCC goes up to 3.0 V or more in the circuit voltage diagram.

  • Page 18 KX-TG3611BX/KX-TG3612BX/KX-TGA361BX 4.5.6. 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 of pin 90 of IC501 is monitored. If a parallel-connected telephone is put into OFF HOOK status, the presence/ absence of a parallel connection is determined when the voltage changes by 0.2 V or more.
  • Page 19 KX-TG3611BX/KX-TG3612BX/KX-TGA361BX 4.5.7. 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 con- nected in parallel is on hook or off hook by detecting changes in the T/R voltage.
  • Page 20 KX-TG3611BX/KX-TG3612BX/KX-TGA361BX 4.5.8. Calling Line Identification (Caller ID)/Call Waiting Caller ID Function: Caller ID 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 21 KX-TG3611BX/KX-TG3612BX/KX-TGA361BX Call Waiting Caller ID 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.
