Store and forward exchange system

Abstract

Abstract PURPOSE:To perform smooth service and to lighten a burden on an exchange operation supervisor by calculating the transmission-start scheduled time of a telegraphic message, received from an originating terminal by an excyange, to be sent to a terminating terminal, and by sending it back to the originating terminal for display. CONSTITUTION:From facsimile FAX terminal 1-n, telegraphic messages addressed to FAX terminal 1-1 are given priority levels and transmitted to message switchboard 2, which stores them in telegraphic-message memory part 5. On the basis of transmission start times addressed to respective terminals, a queue according to priority levels of respective terminals, times required for transmission to respective terminals, the number of staying telegraphic messages, and the volume of information stored in main memory part 4 of switchboard 2, CPU3 calculates the scheduled time of transfmission start for a telegraphic message from teminal 1-n to terminal 1-1 and sends it back to terminal 1-n. Terminal 1-n displays the transmission scheduled time by terminal printer 14 or display part 15 via display control part 13. An originating operator knows the transmission scheduled time and informs the switchboard of an increase in priority at need, at need, so that service can smoothly be performed.
