Abstract

PURPOSE:To simplify the operator interruption to an optional subscriber, by operating a selector to switch a switching relay of the subscriber's circuit to the selector side in the interruption monitor system of the communication system using a time division digital. CONSTITUTION:An interruption monitor circuit BVC is connected to an idle terminal of a selector, and the interruption monitor circuit BVC is connected to one appearance of a general subscriber's circuit LC, and the circuit LC is connected to an operator board ATT through a fixed bus of a time division network, and a selector SEL is operated and a switching relay UAB of the subscriber's circuit is switched to the selector SEL side to cause the operator interruption to optional subscriber's A and B. Consequently, the interruption is caused only by providing the simple circuit BVC.
