Abstract

PURPOSE:To make it possible to use a circuit effectively and adequately even in case that calls converge on one place, by indicating originating restriction by a toll board as occasion demands. CONSTITUTION:On receiving an origination restriction signal from toll board 1, central-station repester 2 stops the transmission of a free-line signal to a radio circuit and, in consequence, base station 3 sends out a transmitting radio wave. When receiving it, radio subscriber 4 becomes ready to receive a call in a queue, so that the originating will be restricted. Once a toll-board operator dials the number of a called radio subscriber in this state, the dial pulse is received by repeater 2 and then converted into a signal suitable to the radio circuit, which is sent out to subscriber 4, thereby making a call. Consequently, the circuit can be used effectively and adequately even in case that calls converge on one place, by indicating the originating restriction by toll board 1 as occasion demends.
