Abstract
PURPOSE:To make the outgoing control possible, by connecting a subscriber and a central office trunk only in the receiving side at a trunk line outgoing time to repeat the dial tone but not transmit the PB signal to the trunk line directly. CONSTITUTION:When the request of a subscriber SUB for trunk line outgoing is received through a path T2 of a four-wire channel SW by a PB receiver PBREC, a central processing device CC acquires a central office trunk BWT to start an office exchange and sets a receiving-side path R1 between a subscriber's circuit LC and the central office trunk BWT. The dial tone transmitted through a trunk line CO is repeated to the subscriber SUB by the receiving-side path R1. Dial numbers are received by the PB receiver PBREC and are checked by the central processing device CC and the transmitted to the trunk line CO through a path T3 and the central office trunk BWT from a PB sender PBSND.
