Abstract

PURPOSE:To accommodate various different kinds of data terminal devices by providing an interface device in matching with the specification of a data terminal device at the terminal device in accommodating different kinds of data terminal devices in an exchange and allowing the said interface device to convert conditions into the unified interface conditions in the exchange. CONSTITUTION:A terminal attribute identification circuit 26 sends attribute such as character type of a data terminal device and data speed set by a key (KEY) 27 to a central controller 23. In sending a sending request command from a data terminal device to a terminal signal converting circuit 21, a sending start request is sent to an exchange main body 15 through a signal form converting circuit 25 and an exchange-side signal converting circuit 24. When the exchange main body 15 is made possible to receive a call, permission information is returned. The permission information is subjected to conversion processing into a character format communicated by a data terminal device by means of the central control circuit 23 and a character transmission/reception circuit 22.
