Abstract

PURPOSE:To set a character message from an input device with full keyboard by providing a data interface circuit sending an input character data from a character data input device to a message processor to a master set and connecting the character data input device with a full keyboard to the data interface circuit. CONSTITUTION:A message setting data from a teletypewriter 4 is converted into an analog signal by a MODEM31 and given to the master set 3 through a trunk line 2. In receiving a voice signal from a trunk line 21 by a telephone set, e.g., 11, the operator of the telephone set 11 inputs a predetermined special number. A central processing unit 9 receiving the special number operates a cross point 23 of the data interface circuit 13 to a channel between the trunk line 21 and the data interface circuit 13. When the message set data is transmitted to the central processing unit 9, after a prescribed processing is applied by the central processing unit 9, the message is transmitted and displayed on a designated key telephone set.
