History

AT&T Long Lines

The American Telephone & Telegraph Long Lines wire, cable, and microwave radio relay network provided long-distance services to AT&T and its customers. The connection to other countries from the United States began here. Formal opening of the United States coast-to-coast connection was on August 17, 1951 via AT&T's network control center in New York City. By the 1970s, 95% of distance and 70% of intercity telephone calls in the United States were carried by AT&T.

Before utilizing microwave relay and coaxial cables, AT&T used lines for long distance service. In 1911, the system connected New York to Denver. The introduction of repeater towers allowed such connections to reach across North America. In the 1930s the company experimented with long-distance coaxial cable. The first long-distance L-carrier coaxial link in 1936 connected Philadelphia and New York. With improved klystrons and other devices devised for World War II, it was quickly determined that relay networks were easy to build, especially over mountainous regions and rough terrain. Coaxial systems connected all major US cities and a system connected New York to Philadelphia, but the primary medium links using the company's dishes.
