<p>PURPOSE:To easily execute multiple address communication in an information processing field even in an information communication network using an electronic exchange system as its heart by executing a switching function being a basic function of the electronic exchange based on a line control request from a host computer. CONSTITUTION:A host computer(HST) 20 applies line control request to an exchange system via an interface device 33. A message processing section 32 decodes the line control request received by a central processing unit(CPU) 30, informs the result to a line control section CC 31 and the CC 31 sets 1:n one-way communication channels 50-5n and 1:1 2-way communication channels 60, 61 of a time division switch device 40. After the execution of the line control by the CC 31, the communication enable state is informed to the HST 20. Thus, the multiple address communication used widely in the field of information processing is executed even in the information communication network using the electronic exchange as its heart.</p> |
