APPENDIX
List of abbreviations and acronyms used
Gives technical standards and design objectives that are necessary to ensure interoperability and to promote commonality for communications equipment and subsystems that are used in TADIL B. This document also establishes acceptable overall subsystem performance and maximum flexibility of subsystems layout in order to satisfy user requirements without the restrictions caused by interface and incompatibility problems.
