Abstract

PURPOSE:To make highly efficient the data exchange, by rewriting the part performing the communication control of a communication control section with the designation from the terminal. CONSTITUTION:Terminals 101-109 having different communication control means are connected to a composite exchanger 120 via an exchange network 110. A communication control device 121 receives the 2nd dial signal information from each terminal and transmits it to a central processing device 125. The device 125 retrieves the communication control program suited to the communication control means at the terminal having call with this information and stores it to the device 121. Thus, since the device 121 is made general-purpose, the efficiency of the data exchange can be increased.
