AIX / 370 was IBM's third attempt to offer Unix-like functionality for their mainframe line, specifically the System / 370 ( the prior versions were a TSS / 370 based Unix system developed jointly with AT & T c. 1980, and VM / IX a VM / 370 based system developed jointly with Interactive Systems Corporation c. 1984 ).

As of February 18, 2008, carriers in the United States were no longer required to support AMPS and companies such as AT & T and Verizon have discontinued this service permanently.

D-AMPS was a digital, 2G standard used mainly by AT & T Mobility and U. S. Cellular in the United States, Rogers Wireless in Canada, Telcel in Mexico, Telecom Italia Mobile ( TIM ) in Brazil, VimpelCom in Russia, Movilnet in Venezuela, and Cellcom in Israel.

* AT & T Mobility-In areas where AT & T Mobility previously had D-AMPS operating on 1900 MHz frequencies, no analog AMPS network existed, and the D-AMPS network on the 1900 MHz frequency was shut down in mid-2007.

However, FuturePhone ( as well as other similar services ) ceased operations upon legal challenges from AT & T and other service providers.

In the early 1960s, AT & T introduced digital telephony first on long-distance trunk lines.

Researchers at the AT & T subsidiary Bell Telephone Laboratories patented coaxial cable in 1929, primarily as a telephone improvement device.

AT & T laid the first L-carrier coaxial cable between New York and Philadelphia, with automatic signal booster stations every, and in 1937 they experimented with transmitting televised motion pictures over the line.

AT & T used the coaxial link to transmit the Republican national convention in June 1940 from Philadelphia to New York City, where it was televised to a few hundred receivers over the NBC station.

These stations were linked together via AT & T's coaxial cable feed, allowing the network to broadcast live television programming to all the stations at the same time.

T-4 and T-5 used coaxial cables, similar to the old L-carriers used by AT & T Long Lines.

ABC-TV began the transition from coaxial cable – microwave delivery to satellite delivery via AT & T's Telstar 301.

AT & T continued to operate the tower until the advent of fiber optic cables and satellites which led to the replacement for the underground coaxial cable network and the use of the 318-foot steel structure now sitting vacant within the eastern Miami County farm fields.

* February 18 – The first Washington, D. C. – New York City telecast through AT & T coaxial cable, in which General Dwight Eisenhower placed a wreath at the base of the statue in the Lincoln Memorial and others made brief speeches, is termed a success by engineers and viewers, although Time magazine calls it " as blurred as an early Chaplin movie.

* First coaxial cables are laid between New York and Philadelphia by AT & T ; they will transmit television and telephone signals.

In the US the cables were predominantly L-carrier coaxial multiplex built by AT & T, who also used them to carry about one third of all civilian long-distance lines as well, as they were much bigger than the military needed.

These stations were linked together via AT & T's coaxial cable feed with the sign-on of WDTV allowing the network to broadcast live programming to all the stations at the same time.

Prior to the breakup, the broadcast networks relied on AT & T Long Lines ' infrastructure of terrestrial microwave relay, coaxial cable, and, for radio, broadcast-quality leased line networks to deliver their programming to local stations.

This was due to there being only three hours for the West Coast branches of the TV networks to receive video for the programming from the East Coast ( live via leased microwave relay or coaxial cable circuits provided by the phone company ( AT & T ) at the time ), and then to record such to kinescope films, and finally to develop the film to be aired three hours later on the West Coast.

Shortly after its launch, Satcom 1 was the first satellite used by broadcast TV networks in the United States, like ABC, NBC, and CBS, to distribute their programming to some of their local affiliate stations which had before, and at that time, relied on AT & T's terrestrial microwave & coaxial networks to distribute & relay programming ( although some of NBC's local affiliates were receiving programming via the satellite on an experimental basis in the late ' 70s ).

Prior to the arrival of Skypath, NBC programming, with the exception of The Tonight Show Starring Johnny Carson, was delivered via coaxial cable and microwave transmission through the facilities of AT & T ( however, NBC did have limited satellite delivery on an experimental basis via their C-band transponder on Satcom F1 beginning with the satellite's launch in 1975 ).

* February 13 – TAT-2, AT & T's second Trans-Atlantic telephone cable, goes into operation.

AT & T made its first postwar addition in February 1946, with the completion of a cable between New York City and Washington, D. C., although a blurry demonstration broadcast showed that it would not be in regular use for several months.

Mu-metal was invented in 1923 by The Telegraph Construction and Maintenance Company Ltd., London, who made the cable, initially, for the Western Union Telegraph Co. Western Union were in competition with AT & T and the Western Electric Company who were using permalloy.

TAT-2 was AT & T Corporation's second transatlantic telephone cable.

TAT-3 was AT & T's third transatlantic telephone cable.

TAT-4 was AT & T's fourth transatlantic telephone cable.

TAT-5 was AT & T's 5th transatlantic telephone cable,

TAT-6 was AT & T's sixth transatlantic telephone cable.

TAT-7 was AT & T's 7th transatlantic telephone cable,

TAT-9 was AT & T's 9th transatlantic telephone cable system, in operation from 1992 to 2004, initially carrying 80, 000 telephone circuits between North America and Europe.

TAT-10 was AT & T's 10th transatlantic telephone cable, in operation from 1992 to 2003, initially carrying 2 x 565 Mbit / s between USA and Norden in Germany.

TAT-11 was AT & T's 11th transatlantic telephone cable, in operation from 1993, initially carrying 2 x 565 Mbit / s between USA and France.

The cable was constructed for US $ 740 million and was supplied jointly by AT & T Submarine Systems, Inc ( now TE Subcom owned by TE Connectivity ), STC Submarine Systems ( acquired by Alcatel-Lucent ) and Alcatel Submarcom.

In 1999, the company hired former assistant attorney general Anne Bingaman, married to Democratic New Mexico Senator Jeff Bingaman, as a Washington lobbyist, paying her $ 2. 5 million between January and June 1999 to try to block licensing of an AT & T, MCI, and Sprint consortium cable from the U. S. to Japan.

Water service is primarily provided by Palmdale Water District ( separate public agency ) and Los Angeles County Waterworks ( part of the County Public Works ); sewer service is provided by the County Sanitation Districts of Los Angeles County ( separate public agency ); electrical service is provided by Southern California Edison ; natural gas service is provided by Southern California Gas ; cable television service is provided by Time Warner Cable ; telephone service is provided by AT & T and Verizon ; refuse pickup and disposal service is provided by Waste Management, Inc of the Antelope Valley under a franchise agreement with the city.

Comcast provides cable services, internet and phone services and AT & T, landline phone service, internet and television services.

The issue came to the fore in the U. S. in 1998, when AT & T announced its plan to acquire TCI, then the nation's largest cable operator.

Cinemax HD is available on Dish Network, DirecTV, Time Warner Cable, Cox Communications, Comcast, AT & T U-verse, Verizon FiOS and other major cable providers, although few providers offer all eight multiplex channels in HD.
