DATA COMMUNICATION SYSTEM

摘要

PURPOSE:To decrease remarkably a relay line connecting an exchange and a computer center and station equipment or the like of each station and also to simplify the operating procedure of subscribers by allowing an identical device to execute in a batch way data processing, communication processing and exchange processing to identical data. CONSTITUTION:The data processing, communication processing and exchange processing are executed in a batch way by an identical device of a station by using a centralized exchange 1 provided with a storage device of hierarchical constitution having partly a high-speed storage section capable of accessing from a time division multiplex transmission line and accessing from a program. A sending terminal 2 transmits data to the high-speed storage section 11 of the centralized exchange 1 via a multiplexer 4 and a line and also informs a processor 14 of a processing content and an incoming terminal number or the like. The processor 14 processes the data stored in the high-speed storage section 11 based on the informed processing content, returns the resulting data after the end of processing to the high-speed storage section 11 and transmits the data to a terminal device 3 having the informed incoming terminal number via the line and the multiplexer 4.
