ABSTRACT:
A diagnostic system for a large, multiple processor data processing system. Diagnostic access between dual diagnostic intelligent consoles and each processor is provided through a diagnostic network of communication links and switching nodes which are independent of normal data processing system communication channels. The diagnostic network consists of two embedded three structure communication networks providing two different diagnostic communication paths to each processor within the data processing system.
