PURPOSE:To improve the transfer efficiency, by providing a vacant/busy state detector and vacant/busy information transfer device for a subscriber exchanger, scanning and detecting the vacant/busy state of all subscribers in the order of allocation, trasferring the state to a data base after consitituting the unit transmission block with detected vacant/busy information and revising the subscriber vacant/busy information at each prescribed period. CONSTITUTION:A subscriber exchanger 2 accommodates a subscriber 1 in a channel network 3 as a conventional exchanger and is connected to a relay line via a trunk 4. A subscriber vacant/busy information detector 8 detects the vacant/busy state of all subscribers in its region in the order of accommodated location at each period, stores the result in a main storage device 7 and a vacant/busy information transfer device 9 picks up vacant/busy information of a prescribed number from the main storage device 7, constitutes a unit transfer block and transfers the block to a data base 10 sequentially. Since the vacant/ busy state is detected at each period and the unit transmission block consisting of a plurality of subscriber vacant/busy information is transferred, the transfer efficiency can be improved and the processing capacity of each device is not affected by the increase of calls. |
