In telephone systems nomenclature, a long line is a transmission line in a long-distance communications network such as carrier systems, microwave radio relay links, geosynchronous satellite links, underground cables, aerial cables and open wire, and Submarine communications cables. In the United States, some of this technology was spun off into the corporate entity known as AT&T Long Distance with the breakup of AT&T in 1984. Prior to then, the AT&T Long Lines division of the Bell System, which was what AT&T called itself when it was responsible for providing both long distance and local telephone service before the 1984 breakup, provided maintenance and installation of long line facilities for the Bell System's long distance service.
Famous quotes containing the words long and/or line:
“You’ll wait a long, long time for anything much
To happen in heaven beyond the floats of cloud
And the Northern Lights that run like tingling nerves.”
—Robert Frost (1874–1963)
“What we are, that only can we see. All that Adam had, all that Caesar could, you have and can do. Adam called his house, heaven and earth; Caesar called his house, Rome; you perhaps call yours, a cobbler’s trade; a hundred acres of ploughed land; or a scholar’s garret. Yet line for line and point for point, your dominion is as great as theirs, though without fine names. Build, therefore, your own world.”
—Ralph Waldo Emerson (1803–1882)
