PURPOSE:To make unnecessary an information storage relay in an outgoing register, by identifying the allocating position of a caller at a common controller with the control from a common controller, when a common controller is started from an outgoing register. CONSTITUTION:When a caller hooks on a handset, a common controller is started, and the caller and an outgoing regiester are connected via a frame with the control of the common controller. When the caller dials a called party's number, the outgoing register counts and stores it, starts the common controller and operates the connector relay between the outgoing register and the common controller. Further, when the common controller requires a call information, ground is transmitted to a control lead, a relay GK is operated through a contact m<3> and the cut-off relay C corresponding to the subscriber is restored with a contact gK<4>. Through the restoration of the relay C, the channel line of the subscriber connected to the outgoing register is given to the common controller and ground is given to the line B through a contact gk<2> to enable the idetification of allocating positon of the subscriber at the common controller. |
