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.

# REDIRECT AT & T Corporation

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.

Cingular renamed itself AT & T and is rolling out some cities with a UMTS network at 850 MHz to enhance its existing UMTS network at 1900 MHz and now offers subscribers a number of dual-band UMTS 850 / 1900 phones.

Music Choice also offers video and audio music programming for cell phone customers through Sprint Nextel and AT & T Wireless Services.

; Entrust IdentityGuard Mini Token: Entrust offers two variants of their OTP token — Entrust IdentityGuard Mini Token OT and Mini Token AT.

The Entrust IdentityGuard Mini Token AT offers time-and event-synchronous, one-time passwords based on the stronger DES / Triple DES algorithm.

The Bourne shell, sh, was written by Stephen Bourne at AT & T as the original Unix command line interpreter ; it introduced the basic features common to all the Unix shells, including piping, here documents, command substitution, variables, control structures for condition-testing and looping and filename wildcarding.

However, the AT & T 210 is a basic phone that reputedly has a REN of 0. 4.

This monopoly made millions of extra dollars for AT & T and Western Electric, and had the secondary effect of subsidizing telephone service, keeping basic local phone service very low — under $ 10 per month, including the leased phone.

Although George Stibitz had foreseen this evolution at AT & T in the 1930s, subsequent generations of engineers, prior to the 1970s, regarded the switch as a piece of hardware, best hard-wired, to handle the basic telephone call where two parties connect, speak and hang up.

As a result of AT & T's merger with SBC, and Verizon's merger with MCI, those telephone companies have an obligation to offer naked DSL to consumers.

** Wired is provided by AT & T ( DSL ).

DSL from AT & T was added in January 2010 for many residents.

AT & T now provides naked DSL throughout most of the country, and Qwest Communications provides it voluntarily.

OFF-NET USAGE If your minutes of use ( including unlimited services ) on other carrier networks (" off-net usage ") during any two consecutive months exceed your off-net usage allowance, AT & T may, at its option terminate your service, deny your continued use of other carriers ' coverage or change your plan to one imposing usage charges for off-net usage.

The floppy controller card was the same as found in the IBM XT and supported up to four 360K drives ( two internal, two external ) but was not compatible with the higher-capacity drives then gaining in popularity, notably the 5. 25 " quad-density (" 1. 2MB ") drives that were standard in the IBM AT and 3. 5 " 720K drives.

Assertiveness Training (" AT ") was introduced by Andrew Salter ( 1961 ) and popularized by Joseph Wolpe.

The IBM PC AT introduced the " AT " (" set 2 ") scancodes, with a different key numbering and where a key release is indicated by an F0 prefix.

Merge was originally developed to run DOS under UNIX System V Release 2 on an AT & T 6300 + (" sixty-three hundred plus ") personal computer.

He is also known for crediting his computer " Shalosh B. Ekhad " as a co-author (" Shalosh " and " Ekhad " mean " Three " and " One " in Hebrew respectively, referring to the AT & T 3B1 model ), and for his provocative opinions, some of which are:

In 1983, Northwestern Bell and AT & T in conjunction with Telesystems and First Data Resources / WATS Marketing, developed a method to use Direct Inward Dialing ( DID ) to handle traffic so call centers no longer had to have dedicated lines or trunk groups as they are called, to handle each telephone number.

The first self-dialed customer-connected long-distance telephone call in North America was made much later on November 11, 1951 when Mayor M. Leslie Denning of Englewood, New Jersey called Mayor Frank Osborne of Alameda, California, using AT & T's Direct Distance Dialing feature.
