Abstract

PURPOSE:To secure the detection with discrimination for the multiplex fault patterns and thus secure a quick and accurate countermeasure to the fault, fractionating the parity check section and furthermore blocking the transmission of the error information to the subsequent positions. CONSTITUTION:Both the parity checker PC1 and the parity generator PG1 are installed at the output side of the time-divisionswitch 200. And in the case of the fault (a), the parity checker PC on the incoming side corresponding junctor highway of the space switch module 20 detects the parity error. In addition, the parity checker PC at the outgoing side also detects the error. Thus the fault can be processed en bloc under the control of the checkers PC since the fault process is carried out through the control circuit 201. In the case of the fault (b), the error is checked through the checker PC1 not by the checker PC for easy distinction. In the case of the fault (c), just one unit of the outgoing side checker PC1 carries out the error detection. And in the case of the fault (d), the error is checked only by the incoming side checker PC of the switch 104. In such way, the fault report is given to the central process module 30 through one unit of the control circuit for one unit of the fault.
