PURPOSE:To attain a high processing capacity by plural processors, by detecting a processing a request from a line by means of scanning by a processing request controlling circuit, and reporting it to a corresponding processor, in a communication control device which is constituted of plural processors. CONSTITUTION:Microprocessor 10-20 execute a line control by a line control program, and a processing request scanning part 30 selects one of the processors by a counting value of a processor counter 50, but it is skipped unless a circuit corresponding to a counting value in scanning displaying circuits 13-23 corresponding to each processor is in scanning state. A line scanning part (not shown in the figure) executes processing to a line connecting part (not shown in the figure) from a command in a line control memory 40, and outputs a processing request when said processing has ended. A line control program outputs a processing request scanning request contents of scanning counters 12-23 corresponding to the processor concerned are supplied to the memory through an input/output bus 11 or 21, a processing request of a corresponding line is read out, and processing corresponding to the processing request is executed. |
