Abstract

PURPOSE:To previously prevent a mistaken connection by connecting a selection signal receiver included in communication control equipment to a monitor line branched from a circuit to a pay station network, monitoring a number that a network control unit transmits to a pay station line and rendering the communication control equipment to stop a calling action if a called number has errors. CONSTITUTION:According to the specified number of an opposite party from the communication control equipment 201, the network control unit 203 transmits a selection signal, that is, a dial pulse or multifrequency to the pay station line thereby connecting an opposite station. At that time, the selection signal receiver 104 in the communication control equipment 201 monitors the telephone number transmitted to the pay station line through a monitor line from a monitor branch part 204. The communication control equipment 201 sequentially compares the monitored called number with the telephone number of the opposite party, which is held in said number holding memory 101, with the aid of a comparison part 102. If they are not the same, a network control part 103 instantaneously stops a call action instruction to the network control unit 203.
