Socioeconomic Impact Assessment: Communications Industry. Phase I. Technical Appendix Description and Documentation of the Current State-of-the-Art. Volume II.
Abstract
The system descriptions contained in this volume differ from those in Volume I along two dimensions. First, the previous system descriptions were functional in nature, and were primarily concerned with system requirements, performance and interconnections. These descriptions, while touching on all of these aspects, placed more emphasis on the design criteria and hardware of the systems and subsystems. Secondly, while Volume I was primarily concerned with current and near-term future systems, this volume will more fully describe the historical and evolutionary development of the systems. As such, it will compliment the material in Chapter Four of Volume I, which assessed innovation and diffusion. The material in this volume is divided into three appendices. Appendix A describes the integration of several DCS and VCS functions into the proposed National Airspace Data Interchange Net-Work (NADIN). Appendix A also describes work in progress on the Voice Switching and Control System (VSCS). Appendix B describes the evolution and current state-of-the-art for Collision Avoidance Systems. Finally, Appencix C supplements the material presented in Volume I on the Intercom/Interphone (IP/IC) systems, and Appendix A regarding VCS. (Author)
