Abstract

The present telephone system in the United States represents more than a century of evolution in voice telephone communications. Since the original telephone patents were issued to Alexander Graham Bell in 1876 there have been enormous technological strides in telecommunications, and today we enjoy a convenient and highly reliable system interconnecting practically every home and business in the country, as well as providing easy access to most foreign nations. The huge telephone network, which is often called the world’s most complex machine, is an incredible system of electronic and mechanical switches, cable and radio links, network management gear, and subscriber premises equipment. It is certainly one of our most valuable national resources. Today, some of the telephone plant is very modern, but a great deal of older equipment is still in use. It is being steadily replaced, but the huge capital costs involved makes replacement a slow process, particularly since most old equipment still works very well.
