Abstract
Comprehensive diagnostic tests and multifeatured control software designed for execution on several host processors help craft to quickly isolate faulty hardware anywhere in the 3B20D Processor. Besides meeting the requirements for Bell System switching systems, the 3B20D diagnostics provide a high degree of modularity and portability using an operating-system-based structure. The diagnostics are used in a wide range of development, production, and maintenance activities throughout the project life cycle. Many features of the system architecture and hardware are provided to allow thorough diagnosis in a time-shared noninterfering manner. Additional features are provided in the diagnostic control structure to extend the DMERT diagnostic capabilities to application systems based on the 3B20D Processor.
