FACSIMILE COMMUNICATION CONTROL SYSTEM |
摘要 |
PURPOSE:To improve the efficiency of utilization of a circuit by assigning infinitely circuits for both general communication and multiple address communication when there are free terminal transmitting circuits or by giving priority to communication whose number of in-use circuits is below the upper value when not. CONSTITUTION:One screen of a picture signal of center-to-terminal multiple address communication for one-address communication is sent from the center to picture signal storage device 1 via terminal-to-center transfer device 2 and stored there. A picture signal of general terminal-to-terminal communication is stored in device 1 via signal transfer device 4 between the ground and facsimile storage converter. Central controller 3 for storage conversion determines the allocation of circuits by controller 6 for terminal circuit allocation and transfers the picture signal from picture signal storage device 1 to terminal facsimile transmission-reception controller 5 to perform picture signal transmission to facsimile terminal device 7. Connection request answering circuit 15, when all-circuit in-use detecting circuit 14 generates output ''1'', sends connection permit signal (e) according to connection request signal (c) or (d). |
