Parallel Connection Detect Circuit/Auto Disconnect 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 16 KX-TG4011N/KX-TG4012N/KX-TG4013N/KX-TGA402N 4.4.6. Calling Line Identification (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.
