Abstract
PURPOSE:To track a calling subscriber automatically even between different telephone exchanges by transferring information, which contains the number of a called subscriber and calling-subscriber tracking display, to a high-priority ladder repeater station and by making a comparison with the calling-party-subscriber's number of a calling subscriber. CONSTITUTION:When a person in charge of maintenance registers on a typewriter TYP the telephone number of a subscriber SUBB who is to track a calling subscriber, an exchange EL2 wherein the SUBB is equipped transmits the telephone number of the SUBB and a calling-subscriber tracking indication signal to a high- priority ladder repeater station ET. The repeater station ET registers the received information in a storage device MEM. As a subscriber SUBA sends a call signal, the CPU (CC2) of the repeater station ET makes a comparison between the telephone number of a party subscriber sent from an exchange EL1 and that of the SUBB stored in the device MEM. When the comparison result shows cnincidence, tracking operation is started and the repeater station ET requests the exchange station EL1 to send the calling-subscriber's number, thereby sending the stbscriber's number, of the SUBA to the exchange station EL2.
