  • Expert system for processing errors in a multiplex communications system
    Patent number: 4881230
    Abstract: A method and apparatus for detecting and analyzing errors in a communications system is described. The method employs expert system techniques to isolate failures to specific field replaceable units and provide detailed messages to guide an operator to a solution. The expert system techniques include detailed decision trees designed for each resource in the system. The decision trees also filter extraneous sources of errors from affecting the error analysis results.
