Abstract

PURPOSE:To offer general calling service to local extension subscribers and subscribers in another station via a trunk line as subscribers to be called generally, by providing general calling patterns without providing a special terminal equipment for every calling subscriber. CONSTITUTION:A general calling subscriber A, after performing off-hook operation, dials a general calling number and the pattern number of subscribers to be called generally. Then, a common controller MK connects the subscriber A to a general calling trunk DSPT and sends information on the pattern number to the trunk DSPT. The DSPT puts subscriber side terminals (b)-(f) in the off- hook state, and the respective terminals are connected to an originating register OR. The trunk DSPT repeats dial pulses, sent by being converted into abbreviated dialing pulses predetermined by the pattern information from the controller MK, to the respective terminals (b)-(f). Those terminals (b)-(f) are treated by the controller MK similarly to the origination of a general extension subscriber.
