Abstract

PURPOSE:To achieve real-time material communication by improving a communicating function, by performing communication by telephone simultaneously with the transmission of material contents, documents, etc., by picture data communication such as facsimile communication. CONSTITUTION:The terminal equipments 1 and 2 of the primary and secondary stations of an orgination side and a termination side are connected mutually by a data transmission line; and the information field part of a transmitted frame 3 is divided into slots A, B..., for transmitting pieces of information, and those slots are used as a communication slot, a facsimile communication slot, and a slot for another kind of data communication. To the terminal equipment 2, a telephone set 4, a facsimile equipment 5, and other devices are connected. While material contents, documents, and the strokes of a brush or pen for drawings are transmitted by facsimile communication, etc., communication is carried out by telephone to improve a communicating function. Thus, the real-time communication of materials is realized to enable communications between terminal equipments and a center information retrieval system.
