The 3B20D Processor & DMERT Operating System: 3B20 Field Utilities
01 January 1983
The term "field utilities" includes a number of tools used by telephone company, Western Electric, and Bell Laboratories support personnel to perform trouble-clearing and routine maintenance activities. Currently, software debugging and investigation tools include the Field Test Set (FTS), the Generic Access Package (GRASP), and IBROWSE, an interactive tool used to "browse" through the contents of main memory. In unusual cases, a Micro-Level Test Set (MLTS) may be used in a troubleshooting mode. The Program Documentation Standard (PDS) Field Maintenance Commands are a collection of tools used to perform more routine operational maintenance on the operating system. Each of these capabilities will be described in this article.
