Consumer-oriented ADSL was designed to operate on existing lines already conditioned for Basic Rate Interface ISDN services, which itself is a switched digital service ( non-IP ), though most incumbent local exchange carriers ( ILECs ) provision Rate-Adaptive Digital Subscriber Line ( RADSL ) to work on virtually any available copper pair facility — whether conditioned for BRI or not.

Rate-Adaptive Digital Subscriber Line ( RADSL ) is a variation of Asymmetric Digital Subscriber Line ( ADSL ) technology.

The ATM technology survived as a low-level layer in most Digital Subscriber Line ( DSL ) technologies, and as a payload type in some wireless technologies such as WiMAX.

The motivation of digital subscriber line technology was the Integrated Services Digital Network ( ISDN ) specification proposed in 1984 by the CCITT ( now ITU-T ) as part of Recommendation I. 120, later reused as ISDN Digital Subscriber Line ( IDSL ).

Computer controlled music is also found in the performance pieces by the Canadian composer Udo Kasemets such as the Marce ( ntennia ) l Circus C ( ag ) elebrating Duchamp ( 1987 ), a realization of the Marcel Duchamp process piece Erratum Musical using an electric model train to collect a hopper-car of stones to be deposited on a drum wired to an Analog: Digital converter, mapping the stone impacts to a score display ( performed in Toronto by pianist Gordon Monahan during the 1987 Duchamp Centennial ), or his installations and performance works ( e. g. Spectrascapes ) based on his Geo ( sono ) scope ( 1986 ) 15x4-channel computer-controlled audio mixer.

Alpha, originally known as Alpha AXP, is a 64-bit reduced instruction set computer ( RISC ) instruction set architecture ( ISA ) developed by Digital Equipment Corporation ( DEC ), designed to replace the 32-bit VAX complex instruction set computer ( CISC ) ISA and its implementations.

Operating systems that supported Alpha included OpenVMS ( previously known as OpenVMS AXP ), Tru64 UNIX ( previously known as DEC OSF / 1 AXP and Digital UNIX ), Windows NT ( until 4. 0 SP6 and Windows 2000 RC1 ), GNU / Linux ( Debian GNU / Linux, Gentoo Linux and Red Hat Linux ), BSD UNIX ( NetBSD, OpenBSD and FreeBSD up to 6. x ), as well as the L4Ka :: Pistachio kernel.
