Abstract

PURPOSE:To process simultaneously a transmission request from plural terminal equipments to one terminal equipment by adding an auxiliary storage device for facsimile communication to an electronic exchange so as to absorb the difference from a communication speed of each facsimile terminal equipment and to accept a transmission request with respect to the terminal equipment in data reception. CONSTITUTION:An auxiliary storage means 13 and an auxiliary storage control means 12 are provided. The auxiliary storage control means 13 controls the data storage and sends the data when the facsimile terminal equipment 11 is idle, continues the data when the facsimile terminal equipment 11 receives a data, and as soon as the facsimile terminal equipment is idle, the data is sent and when the interruption reception request is issued even when the facsimile terminal equipment 11 receives data, the present data is stopped and the data from other terminal equipment 14 designated by interruption is received with priority. Thus, communication time and wait time are not extended.

It is an object of the present invention to have an auxiliary storage device for facsimile communication data, add the reference code and time of a facsimile terminal that has received a reception request as information, and store it in a temporary storage device in units of information, and at the same time store it in a temporary storage device. If the status of the facsimile terminal is vacant, the data is sent, and if the other party's facsimile terminal is receiving data, it continues to accumulate data, and as soon as the facsimile terminal is free, data transmission can be started. Even if the facsimile terminal is receiving data, if an interrupt reception request has been sent, the data currently being received from the auxiliary storage device is stopped, and data from the facsimile terminal specified in the interrupt request is given priority. It is an object of the present invention to provide a temporary storage system for facsimile communication in an electronic exchange that eliminates the above-mentioned drawbacks and prevents the communication time and waiting time from becoming long.
