This book provides in depth knowl- edge on telecommunication switching and good background for advanced studies in communi- cation networks. The entire subject is dealt with conceptual treatment and the analytical or mathematical approach is made only to some extent. For best understanding, more diagrams (202) and tables (35) are introduced wherever necessary in each chapter. The telecommunication switching is the fast growing field and enormous research and development are undertaken by various organizations and firms. The communication networks have unlimited research potentials. Both telecommunication switching and communication networks develop new techniques and technologies everyday. This book provides complete fun- damentals of all the topics it has focused. However, a candidate pursuing postgraduate course, doing research in these areas and the employees of telecom organizations should be in constant touch with latest technologies. -

Scope a. This publication is the keystone document for the communications system series of publications. It provides fundamental principles and guidance to plan, execute, and assess communications system support to joint operations. b. An array of information, underpinned by joint doctrine, is utilized to employ combat power across the range of military operations. The communications system provides the means to synchronize joint forces. c. Reliable, secure, and synchronized information sharing among joint forces, multinational forces, and with non-Department of Defense agencies is essential for effective command and control in today’s network-enabled environment. Information systems and networks provide the means to send, receive, share, and utilize information. The synthesis of advanced communications system capabilities and sound doctrine leads to information superiority, which is essential to success in all military operations. 2. Purpose This publication is the Chairman of the Joint Chiefs of Staff (CJCS) official advice concerning communications in joint operations and provides considerations for military interaction with governmental and nongovernmental agencies, multinational forces, and other interorganizational partners.

No.: Q020/Q060 Project No.: 0900610F-01 s Center for Telecommunications and Advanced Technology McLean, Virginia ABSTRACT This paper introduces some of the newer broadband wireless communications alternatives and describes how they could be used to provide high-speed connections between fixed, transportable, and mobile facilities. We also describe the new integrated service technologies – devices used to bundle voice, data, and video services for transmission over a single link. In this case, it’s a broadband wireless link. Together, the new broadband wireless and integrated service technologies can be used to provide efficient, cost effective, and flexible multi-service provisioning. We introduce this concept and discuss its potential for Intelligent Transportation Systems (ITS). Suggested Keywords: broadband, wireless, integrated service platform, multi-service access device (MSAD), integrated access device (IAD), Intelligent Transportation Systems (ITS) i ii ACKNOWLEDGMENTS The author wishes to thank Mr. Louis Ruffino and Mr. Carl Kain for their technical and editorial contributions to this effort. iii iv TABLE OF CONTENTS SECTION PAGE 1.
