In 2000, the telecommunications boom went bust, and the reason was that new market entrants, known as Competitive Local Exchange Carriers (CLECs), were forced to compete with Incumbents Local Exchange Carriers (ILECs) on the terms of the incumbents. The failure of the CLECs resulted in a net investment loss of trillions of dollars, adversely affecting capital markets and severely depressing the overall telecommunications economy, as well as saddling subscribers with artificially high rates. The chief expense for a new market entrant was purchasing and maintaining one or more Class 5 switches (local service providers) or Class 4 switches (longdistance service providers). These switches cost millions of dollars to purchase and came with expensive maintenance contracts. These switches were also very large and required expensive central office space. Faced with competing for thin margins on local telephone service or thinner longdistance margins against incumbents who enjoyed strong investor support and long depreciation schedules on capital equipment, the demise of many new market entrants was foretold by their balance sheets. The Telecommunications Act of 1996 aimed to introduce competition into the local loop by legally requiring the incumbents to lease space on their switches and in their central offices to any and all competitors. New market entrants first found themselves stonewalled in the courts by the incumbents when attempting to gain legal access to the incumbent s facilities. Once legal access had been gained to the incumbents switching facilities, the incumbents conveniently forgot the orders or otherwise sabotaged the operations of the CLECs in the incumbents switching facilities. Given firstly the astronomical expense of buying and installing Class 4 or 5 switches followed by the legal obstacle of gaining access to Public Switched Telephone Network (PSTN), it is little wonder that six years after the passage of the Telecommunications Act of 1996 only nine percent of American residential phone lines are handled by competitive carriers. Given this dismal figure, it is clear that regulatory agencies such as the Federal Communications Commission (FCC) and the utilities commissions of the 50 states have failed to adequately enforce either the letter or spirit of the Telecommunications Act as regards introducing competition in the local loop. Six years after the passage of the Act, 91 percent of all American households have their choice of telephone service providers: the Regional Bell Operating Company, the Regional Bell Operating Company, or the Regional Bell Operating Company. A competitive local loop environment has two apparently insurmountable obstacles: (1) the high cost of Class 4 and 5 switches and (2) gaining access to the local loop network. As of 2002, despite the guarantees contained in the Telecommunications Act of 1996, it appears obvious that com-

petition will never come in the local loop but will have to come to the local loop in the form of an alternative network. The expense of building and maintaining a competitive network based on Class 4 and 5 switches prohibits a financially successful competitive local loop operation. The only way consumers will enjoy the benefits of competition in the local loop is when alternative technology in switching and, secondarily, access, enable a competitor a lower barrier to entry and exit. The primary problem for competitors to the incumbent telephone companies has been access to the network that consists of copper wires radiating from the central office (where Class 5 and 4 switches are located) to the residence or business. Although a variety of wires provides access to a residence (telephone, cable TV, and electrical) and wireless telephone service has exploded in popularity worldwide, until recently all voice services required expensive Class 5 switches for local service and Class 4 switches for long distance. If telecommunications consumers are to enjoy the benefits of competition in their local loop, an ability to bypass the telephone company central office will have to emerge in the market. This will require an alternative switching architecture and a means of access (cable TV, wireless, and so on). The lack of competition in and to the local loop brings forth the specter of another problem raised by a monolithic telecommunications structure. What happens when major hubs of the PSTN are destroyed in natural disasters, terrorist attacks, or other force majeurs The September 11th attack on the World Trade Center has served to focus attention on the vulnerability of the legacy, circuit-switched telephone network. Verizon, the largest telephone company, had five central offices that served some 500,000 telephone lines south of 14th Street in Lower Manhattan. More than six million private circuits and data lines passed through switching centers in or near the World Trade Center. AT&T and Sprint switching centers in the WTC were destroyed. Verizon lost two WTC-specific switches in the towers, and two nearby central offices were knocked out by debris, fire, and water damage. Cingular Wireless lost six towers and Sprint PCS lost four. Power failures interrupted service at many other wireless facilities.1 Verizon further estimates 300,000 voice business lines, 3.6 million data circuits, and 10 cellular towers were destroyed or disrupted by the events of September 11th, which equates to phone and communications service interruption for 20,000 residential customers and 14,000 businesses.2
