Title: Low traffic band communication system
Inventor: HANEDA TOMOYOSHI
IPC: H04N1/00
Filed: 1985-04-26
Abstract: PURPOSE:To smoothen traffic in a stored communication-processor by discrimi nating between a normal communication call and a low traffic band communica tion call, and by performing the communication processing for the latter by waiting until when the processor's load becomes small. CONSTITUTION:When the low traffic band communication call is transmitted, a facsimile picture information stored communication processor 3 stores the information in its low traffic band communication information storage equipment 18, and interrupts its communication processing until a low traffic is provided. Equipments 14, 15, 16, 17, 19 and 20 gives the traffic level of the processor 3 to a logical operation circuit 22. A time supervisory equipment 21 supplies to the circuit 22 an evaluation value based on an anticipated quantity of traffic corresponding to a present time zone. The circuit 22 judges the state of traffic by using said value, while a low traffic band communication starter 23 judges whether or not the condition for the communication is established. If the condi tion established, a CPU 10 controls the storage 18 to give the stored information for the communication processing for the call being held.
