REGULATING SYSTEM

PURPOSE:To achieve a multiprocessor electronic exchange system which can perform economical, suitable confusing restriction, by providing a function to detect the remaining state of processed request in a communication device connected between an input and output processor and a call processor. CONSTITUTION:Processing request from input/output processors 2o-2i is sequentially stored in a storage circuit 31 in a communication device 30 to advance a count circuit 32. The stored processing request is transmitted to a call processor 40 sequentially and a count circuit 32 is subtracted by the transmission. If many processing requests come and the capability of the call processor 40 is exceeded, the index of the count circuit 32 is gradually increased. A discrimination circuit 33 sets a restriction display flip-flop, when the index of the circuit 32 reaches a prescribed number, and sets a restriction display flip-flop 34 and transmits a restriction signal to the processors 2o-2i to start the restricting operation of the line to an inputted load.
