ing up the equipment for another call. This entire function was the first form of switching. The design soon became problematic, however, because an operator could typically monitor only about 100 positions effectively. The answer, of course, came with the development of the switch first with Strowger s invention, and later from a series of switching innovations that led to the technology we have today. The first semiautomatic switch was installed in Newark, New Jersey, in 1914, and the first truly automatic switch went live in Omaha, Nebraska in 1921. For all this

innovation, however, direct long-distance dialing did not become a reality until 1951. Soon the network had evolved to a point where it could handle thousands of simultaneous calls. As the technology evolved, so too did the business. In 1892 Alexander Graham Bell inaugurated a 950-mile circuit between New York and Chicago, ushering in the facile ability to carry out long-distance telephony. Meanwhile the company continued to change; after acquiring Western Electric it changed its name to American Telephone and Telegraph (AT&T) and, in an ongoing attempt to protect its fiefdom, began buying up small competitors as they emerged. In 1909 the company purchased a controlling interest in Western Union, thus garnering the attention of the Interstate Commerce Commission, the federal agency responsible (as of 1909) for the oversight of American wire and radio-based communications. That responsibility would later be passed on to the newly created Federal Communications Commission (FCC). In 1913, in the first of a series of antitrust decisions, the Kingsbury Commitment forced AT&T to divest its holdings in Western Union, stop buying its competition, and provide free interconnection with other network providers. AT&T did not realize it then, but the Kingsbury Commitment was the harbinger of drastic things to come. In the years that followed, a number of significant technological events took place in telephony. Load coils were created and installed on telephone lines, extending signal strength dramatically and reducing bandwidth requirements for each customer. In 1915, the first repeaters were installed on long-distance telephone circuits, making it possible to install circuits of essentially unlimited length. In fact, later that same year a circuit was successfully installed between New York and San Francisco. In 1934, President Roosevelt created the Federal Communications Commission with the signing into law of the Communications Act of 1934. This act moved industry oversight from the Interstate Commerce Commission to the FCC, and recognized the importance of telephone service, mandating that it would be both affordable and universal. By now, AT&T provided local and long-distance service and offered central office equipment and telephones to more than 90 percent of the market. Not surprisingly, that smacked of monopoly to the federal government, and from that point on they were squarely in the FCC s gun sights. In 1948, AT&T sued the Hush-a-Phone Corporation for manufacturing a device that physically connected to the telephone network. The device, shown in Figure 3-4, was nothing more than a metal box that fit

over the mouthpiece of the telephone, blocking out extraneous noise and providing a degree of privacy to the person using the phone. It had no electrical component to it; it was merely a box. Hush-a-Phone won the case, and the District of Columbia Court of Appeals ruled that AT&T could not prohibit people from making money from devices that did not electrically connect to AT&T s network. In 1949, the Justice Department filed an antitrust suit against AT&T and Western Electric. The result was the consent decree of 1956, which allowed AT&T to keep Western Electric, but restricted them to the delivery of common carrier services. In the early 1960s, inventor Tom Carter created a device called the Carterphone, shown in Figure 3-5. The Carterphone allowed mobile car radios to connect to the telephone network and did require electrical connectivity to AT&T. Initially, AT&T prohibited Carter from connecting his
