Abstract

PURPOSE:To set a public telephone set to the service permission state independently of the detection output of each detecting circuit when the dial control circuit below generates the decision output of a no-charge call number, by providing the dial control circuit in the public telephone set. CONSTITUTION:Dial pulses are given to dial control circuit DC and are counted by a counter to decide whether the dial originating number is a charge call number or a no-charge call number, and decision output FC is output. If the no-charge call number is dialed, dial countrol circuit DC decides it to hold decision output FC as H, and therefore, FF 10N1 is not set, and output Q is L still, and the output of NOR gate 22N holds H, and the switch circuit holds the turning-on state, and dial oscillation of each digit and service dependent upon response of the called subscriber are permitted.
