In order for a telephone (a public transmission circuit terminal) carrying out voice communication with a terminal with an IT function to simultaneously enjoy an application service function on an LAN, a speech data interface for interfacing speech data between the telephone and a speech unit of a LAN terminal is provided, and a correlation table for correlating the telephone with the data terminal is provided. Further, a non-speech data interface for interfacing non-speech data between the data terminal and the LAN terminal. In case data from the LAN terminal is speech data, the speech data is transmitted via the speech data interface to the telephone. In case data from the LAN terminal is non-speech data, the non-speech data is transmitted via the non-speech data interface to the data terminal.
