Abstract

PURPOSE:To prevent the transmission of an inadequate calling-subscriber's number by switching a calling-subscriber's number information extraction circuit corresponding to the kind of a calling-subscriber. CONSTITUTION:When the kind of a specific calling-subscriber is assigned by a dial for assignment by kinds of calling-subscribers, calling-subscriber's-kind discrimination relay MON operates. On the other hand, when assignment by kinds of calling- subscribers is a general call, relay MON is operated to switch a calling-subscriber's number inofrmation extraction circuit, and consequently only a specific calling-subscriber's number set by wiring between terminal MNA 0 and MNA 1, and MNB0- MNB7 of calling-subscriber's number setting part NBG is extracted through the operation of digit control relay ON-S for calling-subscriber's number transmission, so that calling-subscriber's number information extracting relay FW 0, FW 1... will operate. As a result, specific calling-subscriber's numbers are sent out to party units corresponding to relay FW 0, FW 1.... Consequently, when an artificial call from a general subscriber of another station is made by a centralized test rack, a calling number set to the centralized test rack is sent out, so that the error charging of the subscriber of the calling-subscriber's number can be prevented.
