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:
“I don’t know how long it has been since my ear has been free from the roll of a drum. It is the music I sleep by, and I love it.... I shall remain here while anyone remains, and do whatever comes to my hand. I may be compelled to face danger, but never fear it, and while our soldiers can stand and fight, I can stand and feed and nurse them.”
—Clara Barton (1821–1912)
“If the Union is once severed, the line of separation will grow wider and wider, and the controversies which are now debated and settled in the halls of legislation will then be tried in fields of battle and determined by the sword.”
—Andrew Jackson (1767–1845)
