Editorial Reviews

Jack Woehr

The Essential Guide to Telecommunications, Second Edition, by Annabel Dodd, enters my workspace serendipitously. I'm currently contracted to US West (or "US QWest" as the office wag has taken to calling it), so I'm in some position to benefit from the perusal of this volume and to evaluate its content. Executive summary: It's a professional and accurate volume suitable to be presented to novice employees their first day on the job at any company whose core business involves stuffing bits up the line.

There's metal in this book. At a high level, Dodd provides overviews of the myriad of empowering technologies that are heaped together into the telecommunications grid of this continent and our planet. The discussion ranges over switched services, dedicated services, signaling, T-1 to T-3, ISDN, DSL, Frame Relay, ATM, SONET, lines, modems, set-top boxes, the Internet, virtual private networks, PCS, wireless and mobile, satellites, convergence (of telephone and PC, not harmonic), and a good deal more.

There's also wetware interest here. Politics are inseparable from technical evaluation of the network. Legislatures and regulatory bodies dictate to the carriers in the name of preserving the public interest within institutions that inherently possess tremendous powers over access. The Essential Guide contains sections on "Local and Long Distance Providers,""The Bell System Prior to and After 1984," "Evolution from CAPs to CLECs," and a whole chapter on "Local Competition and The Telecommunications Act of 1996." Dodd allows herself a few judicious observations into social implications, such as the effects that merger mania and "cream skimming" are likely to have on universal service. Al Gore even makes a couple of appearances in quotation.

The Essential Guide is pretty current. The map of the surviving RBOCs correctly shows US West's 14-state region, accompanied by the (now erroneous) legend "Purchase by Global Crossing, Ltd. pending)." Which goes to show you that the industry holds surprises even for the experts.

The glossary is adequate in relation to the book, though the bibliography is a little too sparse for a second edition. There's no paucity of telecommunications literature; having delved (for instance) into SONET in sufficient detail to note sideband signaling, the author might have deigned to cite a few tech pieces on this and other protocols, rather than merely list eight other telecom overview books.

Dodd seems to have progressed from industry to academia, rather than the other way around. Her professional bio, (former marketing manager at Bell Atlantic, current faculty member at Northeastern University) suggests that her insights may have been arrived at empirically rather than in the ivory tower. Her book accurately imparts the freighted technical context and dynamic economic and social ambiance of the telecommunications industry in these exiting times from the perspective of a well-informed and technically astute insider. It's a good read.

8: The Internet

The Internet is a medium that has fundamentally changed the pace of business processes and the way organizations exchange information with each other. Businesses sell, place orders, receive orders, collaborate, train employees, provide customer service and bid for products over the Internet. Consumers commonly use the Internet to exchange electronic mail with family members, pay bills, conduct online stock transactions, calculate income tax returns, make travel reservations, shop and conduct research. They also spend time on the Internet playing games, listening to music and viewing entertainment.

The Internet is a connection of multiple networks. The networks communicate with each other over a suite of standardized protocols, Transmit Control Protocol/Internet Protocol (TCP/IP), in which data is broken up into "envelopes" called packets. For the most part, network operators use high-speed routers to transmit these packets. Internet traffic is sent at gigabit speeds. The high-speed lines are the backbone of the Internet. They carry the greatest amount of Internet traffic. The Internet backbone transmits requests for information, entertainment, audio and video broadcasts, email and business-to-business transactions. The different carriers that operate Internet backbone exchange traffic with each other at metropolitan area exchanges (MAEs) and network access points (NAPs).

The Web is a vehicle for multimedia presentation of information in the form of music, audio, video and text. The World Wide Web is not separate from the Internet. It is a way to navigate from resource to resource on the Internet by clicking on high-lighted text or graphics from within browsers. As long as they use World Wide Web browsers, all PCs are compatible with the Web. Users point and click their way from computer to computer on the Internet. Before the World Wide Web was developed, documents on the Internet were available only as text. There were no pictures, no "buttons" to click on to issue commands and no advertising banners. There was also no color; everything was black and white.

Individuals and organizations connect their locations to the Internet via many types of telecommunications services including T-1, T-3, analog lines, digital subscriber line (DSL) services, integrated services digital network (ISDN) and cable TV facilities. Internet service providers (ISPs) aggregate traffic from many users and send it over high-speed lines to the Internet backbone. ISPs maintain routers and servers at their sites. The servers, powerful PCs that can be accessed by many users, perform various functions. They contain customer email, businesses' e-commerce applications and home pages for consumers as well as specialized content such as sports information and online games. Servers are located at hosting sites as well as ISP data centers. Hosting sites, where Web content such as corporate, ecommerce and entertainment sites are kept, have servers with information from, for example, search companies such as AltaVista and online retailers.

The popularity of the Web has made the creation and implementation of technologies that enable sites to handle spikes in traffic and large amounts of traffic imperative. One of these techniques is caching, which spreads content among servers at the "edge" of the Internet, closer to end users. In addition to lowering traffic at each server, caching lowers the cost of bandwidth. It lowers the amount of distance packets travel to access Web pages.

Innovations also have occurred in search engine techniques and formatting email for marketing. Search engines are an important tool for organizing sources of online information. They have become faster and the results are more accurate. Corporations use them in their own Web pages to help employees, potential customers and trading partners find information on the corporate Web. Email is now used as a way to disseminate spam, marketing announcements and newsletters that look similar to Web pages. These email messages use the same method, Hypertext Markup Language (HTML), as used to apply formatting and insert graphics on Web sites.

Despite the technological improvements in the Internet, Internet companies are struggling to find profits. Scores of businesses that operated Web sites have gone out of business. Moreover, it has been generally agreed that advertising as a primary vehicle for underwriting the Internet is not viable. To date, gambling (which is illegal in most states), auctions, pornography, music and games are popular and often profitable on the Internet. While commercial organizations depend on the Internet for contact with customers and vendors, e-commerce where businesses exchange purchase orders and pay bills directly to one another's order entry and accounting systems are in their infancy.

Because the World Wide Web is new, legal, privacy and security questions are being raised that previously have not been addressed in this context. For example, freedom of speech for adults sometimes conflicts with protecting children from unsuitable online material. Online sharing of music and copyrighted articles may interfere with authors' and musicians' rights to earn royalties. In other instances, Microsoft's control of PC operating systems and browsers and AOL Time Warner's market share in instant messaging (IM) may give both companies unfair advantages on the Internet. All of these issues raise interesting questions about privacy, free enterprise and free speech.

World Wide Web technology is used by commercial organizations to create extranets and intranets. Extranets use Web technology to create platforms from which trading partners and customers can communicate. Intranets use the technology for internal portals and browser access to corporate data. The adoption of Internet technologies and protocols for internal use by commercial organizations represents a major impact of the Internet. It has led to faster, more convenient access by employees to corporate information.

The History of the Internet

The Department of Defense's Advanced Research Projects Agency (DARPA) started the Internet in 1969, in a computer room at the University of California, Los Angeles. It wanted to enable scientists at multiple universities to share research information. Advanced Research Projects Agency NETwork (ARPANET), the predecessor to the Internet, was created 12 years after Sputnik, during the Cold War. DARPA's original goal was to develop a network secure enough to withstand a nuclear attack.

The first communications switch that routed messages on the ARPANET was developed at Bolt Beranek and Newman (BBN) in Cambridge, Massachusetts. (BBN was bought by GTE. Bell Atlantic acquired GTE, changed its name to Verizon and spun off BBN as Genuity.) ARPANET's network used packet switching developed by Rand Corporation in 1962. Data was broken up into "envelopes" of information that contain addressing, error checking and user data. One advantage of packet switching is that packets from multiple computers can share the same circuit. A separate connection is not needed for each transmission. Moreover, in the case of an attack, if one computer goes down, data can be rerouted to other computers in the packet network. TCP/IP, the protocol still used on the Internet, was developed in 1974 by Vint Cerf and Robert Kahn. It supports a suite of services such as email, file transfer and logging onto remote computers.

In 1984, as more sites were added to ARPANET, the term Internet started to be used. The ARPANET was shut down in 1984, but the Internet was left intact. In 1987, oversight of the Internet was transferred from the Department of Defense to the National Science Foundation.

While still used largely by universities and technical organizations, applications on the Internet expanded from its original defense work. In particular, newsgroups used by computer hobbyists, college faculty and students, were formed around special interests such as cooking, specialized technology and lifestyles. The lifestyles newsgroups included sexual orientation (gay and lesbian), religion and gender issues. Computer-literate people were also using the Internet to log onto computers at distant universities for research and to send electronic mail.

The Internet was completely text prior to 1990. There were no graphics, pictures or color. All tasks were done without the point-and-click assistance of browsers, such as Netscape and Internet Explorer. Rather, people had to learn, for example, UNIX commands. UNIX is a computer operating system developed in 1972 by Bell Labs. UNIX commands include: m for Get Mail, j for Go to the Next Mail Message, d for Delete Mail and u for Undelete Mail. The Internet was not for the timid or for computer neophytes.

The advent of the World Wide Web in 1989 and browsers in 1993 completely changed the Internet. The World Wide Web is a graphics-based vehicle to link users to sources of information. It is based on a method whereby users "click" on graphics or text to be transferred to a site where information can be accessed. In 1993, the Mosaic browser was developed at the University of Illinois as a point-and-click way to access the World Wide Web. This opened up the Internet to users without computer skills. It is no longer necessary to learn arcane commands to open mail, to navigate from site to site for research or to join chat or newsgroups.

In 1995, the National Science Foundation turned the management of the Internet backbone over to commercial organizations. Commercial networks such as Sprint, UU-NET (now part of WorldCom) and Cable & Wireless carry a large portion of the back-bone Internet traffic. Backbones are analogous to highways that carry high-speed traffic.

Bulletin Board Systems (BBSs)

Bulletin boards were used independently from the Internet. They allowed people with modems connected to their computers to read information and post information on a PC.

Users throughout the 1980s used modems, personal computers, communications software and telephone lines to dial into information on other computers. Many bulletin boards were used for "chats" and to exchange ideas around specific hobbies. For example, callers would dial in and type ideas or experiences they had with new software or computer equipment. The World Wide Web has largely replaced bulletin boards.

Enormous changes in telecommunications occurred in the two years between the second and third editions of The Essential Guide to Telecommunications. The Essential Guide to Telecommunications is intended as a road map clarifying technologies, history and trends in telecommunications. Technological innovations in fiber optics and attendant lower costs has led to the construction of vast networks. The book contrasts the glut of these fiber optic networks in long distance routes and some urban areas with their scarcity in developing countries, rural and most suburban regions.

The Essential Guide to Telecommunications explains how technology and regulatory factors impact each other. Deregulation and the presence of competition have resulted in the development of technological innovations. These innovations, particularly those in gigabit Ethernet and optical switching, are examined.

Cellular service has grown tremendously in the last decade. It is a key technology for providing basic voice service in large parts of the world. The book examines technologies used to provide greater capacity for basic voice service in fast growing urban areas, rural communities and tall skyscrapers. It also explains the advanced cellular technologies for transmitting higher speed data and accessing the Internet over wireless networks. It also addresses the concerns about safety. It is not known what impact fears about cancer and driving safety will have on the cellular market.

The Essential Guide to Telecommunications, third edition reviews telecommunications in Europe, Asia and Latin America, as well as in developing countries, and the wide-reaching impact of wireless technology in these areas. Deregulation of local long distance and international services, as well as industry structure and major carriers, are covered. The structure of the telecommunications industry and steps in deregulation are examined in key areas of the world. The pace of adoption of technologies, such as high-speed Internet access, also is highlighted. The significance of a strong telecommunications infrastructure on the economy and on international trade is widely recognized and has prompted governments' attention worldwide.

The Essential Guide to Telecommunications, third edition presents profiles of industry segments and vendor types to provide readers an understanding of the industry. The roles of Internet service providers, backbone Internet providers, competitive local exchange carriers, utilities and cable TV companies are explained. The number of network providers and resellers and the fast pace of mergers has created new layers of complexity. In addition, regulatory rulings and the Telecommunications Act of 1996 are examined in light of their impact on consumers, commercial organizations and carriers.

The language and significance of important telecommunications technologies are explored. The Essential Guide to Telecommunications, third edition is not intended to be a deeply technical book. Rather, it is an overview of technologies and an explanation of the structure of the telecommunications industry. Technologies important in competition for local calling, high-capacity communications, third generation wireless services and Internet access are clarified. Intertwined with high-level technical explanations are examples of how the various vendors interconnect their networks. The book explains key technologies and options available for small and large organizations and consumers. It further explores significant trends, applications and the impact of the Internet.

This book is intended for non-technical people working in the field of telecommunications, laymen interested in learning more about the field and people responsible for the administration of telecommunications services for their organizations. They include regulatory staff, salespeople, law firms, research organizations, marketing personnel, human resources professionals, project managers, telecommunications managers and high-level administrators.

The Essential Guide to Telecommunications, third edition starts out with interpretations of fundamental concepts so that readers will have a basis for understanding more complex, new telecommunications services. It examines the structure of the industry, local competition, regulatory proceedings, the Internet, convergence and wireless services.

Along with explanations of technology are examples of applications and historical highlights. How the industry evolved and how the technology changed is explained. The stories and descriptions that accompany the technical details are key to the book.
