Abstract

PURPOSE:To attain multiple address communication between terminal devices having different protocols by providing a multiple address communication control section, a multiple address communication control memory and a protocol control section to a relay exchange connected to data terminal devices having different forms of protocol. CONSTITUTION:Data terminal devices 11-1m are connected to a relay line exchange 31 via subscriber exchanges 21-2m by using a different protocol. The relay line exchange 31 consists of a channel device 41, a central processor 42 and a multiple address communication controller. For example, in applying multiple address communication from the data terminal device 11 to the terminal devices 12-1m, data is stored once in a memory in a multiple address communication is applied to the stored data at each terminal device having an identical protocol through the subscriber exchanges 21-2m via the channel device 41 in a form corresponding to each protocol through the control of a central processing unit 42. Thus, multiple address communication is executed easily while including the transmission between terminal devices with different protocols.
