to guarantee that a customer could freely select their long-distance provider of choice. If they wanted to use MCI s service instead of AT&T s, a simple call to the local telephone company s service representative would result in the generation of a service order that would cause the customer s local service to be logically disconnected from AT&T and reconnected to MCI so that long-distance calls placed by the subscriber would automatically be handed off to MCI. The problem of equal access to customers for the three long-distance providers was solved. Since 1984 the telecommunications marketplace has continued to evolve, sometimes in strange and unpredictable ways. Harold Greene oversaw the remarkable transformation of the industry until his death in January of 2000. Over time, the seven RBOCs slowly accreted to a smaller number as SBC, Pacific Bell, and Ameritech joined forces, sucking SNET into their midst in the process; NYNEX and Bell Atlantic danced around each other until they became Verizon, pulling GTE into the fray; and Qwest acquired USWest. Only Bellsouth remains as a standalone suitor from earlier days, and none of them are called RBOCs anymore they re incumbent local exchange carriers (ILECs). A host of new players emerged from the proverbial woodwork including bypassers, which became competitive access providers (CAPs), which in turn became competitive local exchange carriers (CLECs). Service, now the favored watchword, has given rise to DLECs, BLECs, ISPs, ASPs, and LSPs. Old-timers remember when the world was fine with just BSPs. (Sorry, inside joke.) In 1996 the FCC released the Communications Act of 1996, designed to revamp the Communications Act of 1934 and make it friendlier to the services carried by network providers today. It also was

designed to address the requests by ILECs to become long-distance providers through a 14-point checklist that they were required to complete before being considered for entry into the long-distance market. None of them ever complied totally with the demands, and as we will see in the regulatory chapter, significant changes have occurred since 1996. Overall, the market continues to liberalize. Western Electric has ceased to exist and Lucent has taken its place. The Internet has become the next great technology and service frontier, and both existing and new service providers are leaping at its promises of wealth and riches. Outside the United States, telecom companies once considered primitive rival the level of services offered in the United States, and in spite of the telecom meltdown that plagued the industry for several years, innovation continues and new players spring up like early morning mushrooms. Let s turn our attention now to the network itself.
The Telephone Network
Sure, I know how it works. You pick up the phone, dial the numbers, and wait. A little man grabs the words, runs down the line, and delivers them to whomever I m calling. It seems just about that simple. I mean, come on how complicated can it be It s just a telephone call. Thus was described to me the overall process of placing a telephone call by a fellow on the street, whom I once interviewed for a video I was creating about telephony. His perception of the telephone network, how it works, and what it requires to work is similar to most peoples . Yet the telephone network is without question the single greatest and most complex agglomeration of technology on the planet. It extends its web seamlessly to every country on earth, providing instantaneous communication for not only voice, but for video, data, television, medical images, sports scores, music, high-quality graphics, secure military intelligence, banking information, and teleconferences. Yet it does so with almost complete transparency and with virtually 100 percent availability. In fact, the only time its presence is noticed is when it isn t there as happened on 2nd Avenue in New York, in Hinsdale, Illinois following a major central office fire, and in Chicago following a flood that isolated the Mercantile Exchange and placed hundreds of customers out of service. How the network works is something of a mystery to most people, so we re going to dissect the typical telephone network and examine its anatomy, complete with pictures. This section is not for the squeamish.
