  • Telecommunications Infrastructure for Electronic Delivery 3
    Telecommunications Infrastructure for Electronic Delivery 3 SUMMARY The telecommunications infrastructure is vitally important to electronic delivery of Federal services because most of these services must, at some point, traverse the infrastructure. This infrastructure includes, among other components, the Federal Government’s long-distance telecommunications program (known as FTS2000 and operated under contract with commercial vendors), and computer networks such as the Internet. The tele- communications infrastructure can facilitate or inhibit many op- portunities in electronic service delivery. The role of the telecommunications infrastructure in electronic service delivery has not been defined, however. OTA identified four areas that warrant attention in clarifying the role of telecommunications. First, Congress and the administration could review and update the mission of FTS2000 and its follow-on contract in the context of electronic service delivery. The overall perform- ance of FTS2000 shows significant improvement over the pre- vious system, at least for basic telephone service. FTS2000 warrants continual review and monitoring, however, to assure that it is the best program to manage Federal telecommunications into the next century when electronic delivery of Federal services likely will be commonplace. Further studies and experiments are needed to properly evaluate the benefits and costs of FTS2000 follow-on options from the perspective of different sized agencies (small to large), diverse Federal programs and recipients, and the government as a whole. Planning for the follow-on contract to FTS2000 could consider new or revised contracting arrangements that were not feasible when FTS2000 was conceived. An “overlapping vendor” ap- proach to contracting, as one example, may provide a “win-win” 57 58 I Making Government Work situation for all parties and eliminate future de- national infrastructure will be much stronger if bates about mandatory use and service upgrades.

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.

  • Routing Management in the PSTN and the Internet: a Historical Perspective
    Routing Management in the PSTN and the Internet: A Historical Perspective Deep Medhi1 1 University of Missouri–Kansas City, Kansas City, Missouri, USA Abstract. Two highly visible public communication networks are the public- switched telephone network (PSTN) and the Internet. While they typically pro- vide different services and the basic technologies underneath are different, both networks rely heavily on routing for communication between any two points. In this paper, we present a brief overview of routing mechanisms used in the PSTN and the Internet from a historical perspective. In particular, we discuss the role of management for the different routing mechanisms, where and how one is similar or different from the other, as well as where the management aspect is heading in an inter-networked environment of the PSTN and the Internet where voice over IP (VoIP) services are offered. 1 Introduction Two highly visible public communication networks are the public-switched telephone (PSTN) and the Internet. The PSTN provides voice services while the Internet provides data-oriented services such as the web and email (although voice communication over the Internet is now possible). In both these networks, information units need to be routed between two points. In the PSTN, the unit of information is a call, while in the Internet the unit is a datagram (packet). Thus, in each network, routing plays a significant role so that information units can be delivered efficiently. To accomplish efficient routing, various supporting management functions also play critical roles. Routing in both the PSTN and the Internet has evolved over the years; for details on routing, refer to books such as [1, 9, 8, 16, 19, 24].
