Abstract

PURPOSE:To carry out the fault detection and identification for the call system via the higher-rank processor by providing the inter-processor interface circuit between the higher-rank processor and the call-system interface circuit, thus ensuring execution of the control action for the resource switching and others. CONSTITUTION:Inter-processor interface circuit 9 is provided between processor 5 and call-system interface circuit 6 in the function dispersion type multi-processor system telephone exchange which contains higher-rank processor 5 performing the resource control and lower-rank processor 8 performing the direct control of call system 1. Thus a direct access is given to the fault information storage area of lower-rank processor memory 7 via the control command given from processor 5 to make possible the non-answer identification to the command of processor 5 at the abnormal time of processor 8 and its subsequent processors. Then the fault detection and identification is carried out for system 1 and processor 5 through circuit 6. In this way, the control action is carried out for the resource switching and others.
