This standard applies to the interconnection of data terminal equipment and numerical control equipment at the tape reader interface. The data terminal would typically be connected to a remote data source/sink such as a computer. This standard defines: This standard is applicable for the interchange of signals when used in conjunction with electronic equipment, each interchange circuit of which has a single return (signal ground) that can be interconnected at the interface point. Figure 1.1, typical installation, shows how this standard should be applied to a typical tape reader interface of numerical control equipment.

The role of CM, within any one company's organization, on the development and production of a product has been established by internal company needs or imposed by customer dictum. (As used hereinafter, in order to reduce any confusion, computer programs, components, software, hardware, firmware, etc., are included in the designation "PRODUCT".) The primary focus of this Bulletin is directed toward the Buyer and Supplier personnel who will be managing hardware products in the production phase and software products in the full-scale development phase. The trend in DoD is toward expanded use of standardized components and subassemblies, using competitive reprocurement. The DoD needs to know the full span of CM requirements which should be included in the production contract and the management tasks that will have to be accomplished.

This Bulletin is intended for use as a guide and defines the terms and definitions to be used during the development, documentation, verification, and delivery cycles of new and modified computer software. It lists and defines the most common terms currently used in the world of computer software configuration management. There has been no attempt to compete with some of the more formal documents in use within the software programming community.

This standard for Numerical Machine Control Perforated Tape is intended to serve as a guide in the coordination of equipment design, to minimize the number of sizes and codes of perforated tape used, and to minimize the variety of perforated tape preparation equipment required by users of numerically controlled machines.

This standard establishes the performance requirements for the control of the electromagnetic emission and susceptibility characteristics of electronic, electrical, and electromechanical equipment and subsystems designed or procured for use in severe electromagnetic environments such as ships, aircraft, spacecraft, armored vehicles, etc. Such equipment and subsystems may be used independently or as an integral part of other subsystems or systems.

The primary focus of this standard is information of interest to Configuration Management (CM) practitioners related to the performance of CM functions as products are conceived, proposed, defined, developed, produced, operated, maintained, modified, and disposed. This information is stored when generated and, from time to time, must be moved or shared with others. This standard, through the use of the Data Dictionary, defines real world things of interest to the CM practitioner, which are the foundation of the following CM functional areas, and are needed for effective data exchange and interoperability: Configuration Management Planning and Management Configuration Identification Configuration Change Management Configuration Audit Configuration Verification Configuration Status Accounting The Data Dictionary [21] defines terms that are used to define these objects of interest, which are listed below.

This handbook is intended to assist the user to understand the ANSI/EIA-649B standard principles and functions for Configuration Management (CM) and how to plan and implement effective CM. It provides CM implementation guidance for all users (CM professionals and practitioners within the commercial and industry communities, DoD, military service commands, and government activities (e.g., National Aeronautics and Space Administration (NASA), North Atlantic Treaty Organization (NATO)) with a variety of techniques and examples. Information about interfacing with other management systems and processes are included to ensure the principles and functions are applied in each phase of the life cycle for all product categories.
