Alascom
Alascom, Inc., d/b/a AT&T Alaska, is an Alaskan telecommunications company; specifically, an interexchange carrier (IXC). AT&T Alascom is currently a wholly owned subsidiary of AT&T Inc. AT&T Alascom, previously known as Alascom and many other names, was the first long-distance telephone company in Alaska. AT&T Alascom has extensive telecommunications infrastructure in Alaska, including three satellites, undersea and terrestrial cables containing optical fiber, and numerous earth stations. Unlike most of the United States, AT&T had no role in Alaskan telecommunications as a local or long distance telephone provider until the purchase of Alascom in 1995. Alaska was also never served by any of the Regional Bell Operating Companies. Alascom and General Communications, Inc. have been the two primary competitors for long-distance telephone service in Alaska since GCI's founding in 1979. History The company began in 1900 when the U.S. Congress authorized the U.S. Army Signa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
White Alice Communications System
The White Alice Communications System (WACS, "White Alice" colloquially) was a United States Air Force telecommunication network with 80 radio stations constructed in Alaska during the Cold War. It used tropospheric scatter for over-the-horizon links and microwave relay for shorter line-of-sight links. Sites were characterized by large parabolic, tropospheric scatter antennas as well as smaller microwave dishes for point-to-point links. The system connected remote Air Force sites in Alaska, such as Aircraft Control and Warning (AC&W), Distant Early Warning Line (DEW Line) and Ballistic Missile Early Warning System (BMEWS), to command and control facilities and in some cases it was used for civilian phone calls. The network was originally operated by the USAF, but was turned over to RCA for operations after 1969. The opening of satellite communication links in the 1970s made the system obsolete, and in 1979 it was replaced by an RCA satellite link that connected all of the stations ...

American Telephone & Telegraph
AT&T Corporation, originally the American Telephone and Telegraph Company, is the subsidiary of AT&T Inc. that provides voice, video, data, and Internet telecommunications and professional services to businesses, consumers, and government agencies. During the Bell System's long history, AT&T was at times the world's largest telephone company, the world's largest cable television operator, and a regulated monopoly. At its peak in the 1950s and 1960s, it employed one million people and its revenue ranged between US$3 billion in 1950 ($ in present-day terms) and $12 billion in 1966 ($ in present-day terms). In 2005, AT&T was purchased by Baby Bell and former subsidiary SBC Communications for more than $16 billion ($ in present-day terms). SBC then changed its name to AT&T Inc. Today, AT&T Corporation continues to exist as the long distance subsidiary of AT&T Inc., and its name occasionally shows up in AT&T press releases. Buildings with AT&T logo * AT&T Huro ...

Optical Fiber
An optical fiber, or optical fibre in Commonwealth English, is a flexible, transparent fiber made by drawing glass (silica) or plastic to a diameter slightly thicker than that of a human hair. Optical fibers are used most often as a means to transmit light between the two ends of the fiber and find wide usage in fiber-optic communications, where they permit transmission over longer distances and at higher bandwidths (data transfer rates) than electrical cables. Fibers are used instead of metal wires because signals travel along them with less loss; in addition, fibers are immune to electromagnetic interference, a problem from which metal wires suffer. Fibers are also used for illumination and imaging, and are often wrapped in bundles so they may be used to carry light into, or images out of confined spaces, as in the case of a fiberscope. Specially designed fibers are also used for a variety of other applications, some of them being fiber optic sensors and fiber lasers. ...

Alaska Communications System (ACS)
The Alaska Communications System (ACS), also known as the Washington-Alaska Military Cable and Telegraph System (WAMCATS), was a system of cables and telegraph lines authorized by the U.S. Congress in 1900 and constructed by the U.S. Army Signal Corps. The communications lines were to serve both military and civilian needs in the territory of Alaska. By 1904, ACS comprised some of undersea cable, over of land lines, and a wireless segment across at least . On May 15, 1936 WAMCATS was renamed the U.S. Army Alaska Communications System. The Alaska Communications System remained under the control of the Army Signal Corps until 1962 when it was taken over by the U.S. Air Force. The ACS handled the radioteletype, radio telephone, 500 kHz ship-to-shore frequencies, collected communications intelligence, and other services for more than half a century in Alaska. The Signal Corps (United States Army), Army Signal Corps (which develops, tests, provides, and manages communications and info ...
