  • Page 17 KX-TG6071BXM/KX-TGA601BXM 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 18 KX-TG6071BXM/KX-TGA601BXM 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 19 KX-TG6071BXM/KX-TGA601BXM 4.5.8. Calling Line Identification (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.
