accelerated, installed, and put into service to carry the traffic that would normally have flowed through the 2nd Avenue office. Within 24 hours, miracles were underway. Service had been restored to all affected medical, police, and fire facilities. The day after the fire, a new main distribution frame had been located at Western Electric s Hawthorne manufacturing facility and was shipped by cargo plane to New York. Luckily, the third floor of the building had been vacant and was therefore available as a staging area to assemble and install the 240foot-long iron frame. Under normal circumstances, from the time a frame is ordered, shipped and installed in an office, 6 months elapse. This frame was ordered, shipped, installed, and wired in 4 days. It is almost impossible to understand the magnitude of the restoration effort, but the following numbers may help. Six thousand tons of debris were removed from the building and 3,000 tons of material was installed including 1.2 billion feet of underground wire, 8.6 million feet of frame wire, 525,000 linear feet of exchange cable, and 380 million conductor feet of switchboard cable. Five million underground splices hooked it all together. 30 trucking companies, 11 airlines, and 4,000 people were pressed into service. And just after midnight on March 21, 22 days following the fire, service from the building was restored to 104,000 subscribers. Normally, the job would have taken more than a year. But because of the Bell System s remarkable ability to marshal resources during times of crisis, the building was restored in less than a month. AT&T Chairman John DeButts:

In the last couple of weeks, I have had the opportunity to observe at first hand the strength of the organization structure that the Justice Department s antitrust suit seeks to destroy. This service restoration has been called a dramatic accomplishment rightly. But only in its urgency does the teamwork demonstrated on this occasion differ from the teamwork that characterizes the Bell System s everyday job.

Of course, the antitrust suit, now known universally as Divestiture, went forward as planned, beginning in 1984. The Bell System became a memory, with just as many people hailing its death as mourning it. And while there is much to be said for the innovation, competitive behavior and reduced prices for telecommunications services that came from the breakup of the Bell System, it is hard to read an account such as the previous one without a small lump in the throat. In fact, most technology historians conclude that we could not build the Bell System network today. To understand the creation of a system that could accomplish something as remarkable as the fire recovery described previously, let s take

As early as 1677, inventor Robert Hooke, who formulated the theory of planetary movement, demonstrated that sound vibrations could be transmitted over a piece of drawn iron wire, received at the other end, and interpreted correctly. His work proved to be something of a bellwether, and in 1820, 143 years later, Charles Wheatstone transmitted interpretable sound vibrations through a variety of media including thin glass and metal rods. In 1831, Michael Faraday demonstrated that vibrations such as those made by the human voice could be converted to electrical pulses. Needless to say, this was fundamental to the eventual development of the telephone. Bernard Finn is the Curator of the Smithsonian s National Museum of American History. His knowledge of the world of science and its vanguard during the heady times of telephony s arrival is unparalleled. He observes that America was a bit of a backwater as far as science was concerned. The inventive climate of that early part of the century was largely [focused on] mechanical inventions, he notes. Even the early electrical stuff was basically mechanical and the machine shop was the center of inventive activity. With the invention of the telegraph, which occurred simultaneously in the United States, England, and Germany in the 1830s, it became possible to communicate immediately across significant distances. By the second half of the nineteenth century, three individuals were working on practical applications of Faraday s observations. Alexander Graham Bell, a speech teacher for the hearing impaired and a part-time inventor; Elijah Gray, the inventor of the telegraph and an employee of Western Electric; and Thomas Edison, an inventor and former employee of Western Union were all working on the same problem: how to send multiple simultaneous messages across a single pair of wires. All three invented devices that they called harmonic telegraphs; they were nothing more than frequency division multiplexers, but for the time were remarkably advanced, conceptually. The original devices that they created performed the multiplexing task mechanically by vibrating metallic reeds at different frequencies. The frequencies would pass down the line and be received correctly at
