An international ISDN high-speed, high-volume, packet-switching transmission protocol standard. ATM uses short, uniform, 53-byte cells to divide data into efficient, manageable packets for ultrafast switching through a high-performance communications network. The 53-byte cells contain 5-byte destination address headers and 48 data bytes. ATM is the first packet-switched technology designed from the ground up to support integrated voice, video and data communication applications. It is well-suited to high-speed WAN transmission bursts. ATM currently accommodates transmission speeds from 64 Kbps to 622 Mbps. ATM may support gigabit speeds in the future.]

Advanced Intelligent Network [architectural concept for the creation and provision of telecom services. The local exchange carriers in the U.S. are developing the next generation of network technology, called the Advanced Intelligent Network. This technology promises to bring advanced capabilities to residential, business, and mobile customers on the local network level - capabilities that previously have been available either only in the long-distance networks or not at all.]

Abstract Syntax Notation One [OSI(1) standard for encoding and decoding information, used by CMIP and - as a subset - SNMP for defining low level MIB objects; machine independent formal description language for the data itself and information regarding the type of data, composed of a transaction segment and a component segment, presentation Layer service, see also SMI]

Asynchronous Transfer Mode [base for future broadband ISDN, 53 Byte packets, current standards: SONET/SDH, DS3, TAXI and Fiber Channel system, user network interface has to support bandwidths of 155 Mbs or 600 Mbs. An international ISDN high-speed, high-volume, packet-switching transmission protocol standard. ATM uses short, uniform, 53-byte cells to divide data into efficient, manageable packets for ultrafast switching through a high-performance communications network. The 53-byte cells contain 5-byte destination address headers and 48 data bytes. ATM is the first packet-switched technology designed from the ground up to support integrated voice, video and data communication applications. It is well-suited to high-speed WAN transmission bursts. ATM currently accommodates transmission speeds from 64 Kbps to 622 Mbps. ATM may support gigabit speeds in the future.]

Common Desktop Environment [graphical user interface as well as development environment, ensures run time compatibility and portability at heterogenous unix systems, opposing MS Windows NT, designed by HP (HP VUE), IBM (IBM CUA), Novell (UnixWare Client Tools) and SunSoft (Open Look Deskset Tools), available in HPUX 10.10; replaces HP VUE]

Code Division Multiple Access(2) [developed by the military, voice is digitalized and then mixed with a random like code. Total signal (voice and random-like code) is transmitted over a wide band of frequencies (e.g. 10 Mhz). Used in industrial standard IS-95. Currently not used in mobile public phone systems yet. Vs FSMA or TDMA]

Common Management Information Protocol [OSI(1) Network Management Protocol; used by manager and agent processes to exchange management informationes the agent/manager paradigm to communicate management information between systems; differs from SNMP in that it is more rigorous, is designed for open systems, and is an association-oriented protocol, requiring the two communicating CMIP processes to establish an association before sending any management messages; defined in ISO standard 9596-2, vs. TCP/IP and SNMP]

Digital European (or Enhanced) Cordless Telecommunications [2nd generation cordless telephone standard, designed to be capable of supporting very high traffic densities (up to basic rate ISDN) by 10 RF carriers * 12 duplex voice channels per carrier (=120 voice channels) per BTS, at 1895-1906 MHz (private) and 1906-1918 MHz (public), with a proposed extension to a 30 MHz frequency band, with TDMA/TDD access technique, GMSK modulation technique, making it suitable for low mobility-high capacity, vs GSM900, concentrated usage environments such as city center offices and transport hubs, developed in Europe, see also PHS]

Element Management System(2) [helps to manage individual devices like modems or routers tied to corporate networks and can support an industry standard for device mgmt. Can also manage services (e.g. inbound and outbound calling services) and provide realtime info about faults, Trouble Tickets, performance and problem resolution. For a class of managed objects]

ETS for "Golden Numbers" [confirms the standard key pad layout into four rows of three with the numbers running from left to right from 1 to 9 and then *, 0, # on the bottom row; it then assigns alphabetic letters to the keypad numbers; the 1 has no letters assigned; the 2 gets a, b, c; the 3 d, e, f; and so on with three letters each until the 7, which gets p, q, r, s; the 8 gets t, u, v and the 9 w, x, y, z.]

Frequency Division Multiple Access [used by existing cellular systems by dividing the total band allocated to a cellular operator (25MHz) into discrete channels of a bandwidth of 30 kHz each. With 833 channels available and each conversation requiring two channels, 416 pairs of frequency are available to each operator, cheaper than TDMA or CDMA]

Guideline for Definition of Managed Objects [defines standard templates describing managed Object Classes and their services with their attributes, notifications, behaviors operations and actions supported by the managed object, defined by X.722/ISO 10165-4, a more complex object specification language than e.g. Concise MIB or Common OV]

Global System for Mobile communications [originally: Groupe Speciale Mobile, pan-European ISDN compatible digital cellphone standard (low capacity-high mobility system, vs. DECT), frequency bands: 905-914 Mhz, 950-959 Mhz, on demand 890-915 Mhz and 935-960 Mhz, 2nd generation standard, phase 2+ implementations: hi speed data transmission (19.2 up to 64 kb/s), generalised packet radio services, GSM900/DCS1800 dual-band operation, interworking between GSM900 and DECT, and CCBS(2), w/w 130 operators (Jan96)]

International Cryptography Framework(2) [new security solution for the internet and eCommerce; details include a four part architecture; ICF consists of 1) a host system which delivers secured applications to the end user, 2) a cryptographic unit (a hardware based encryption engine), 3) a policy token (software that tells the cryptographic unit what level of encryption is desired by company policy and allowed by governmental restrictions) and 4) a network security server run by a certified organization]

Mediation Device(1) [computers, which mediate between "old" switching equipment and new IN services by adapting from proprietory to standard interfaces, by converting to a common information model or by offloading of management functions from OS (like buffering, filtering, local archival or security), in FMP1.1: functional block which collects events from NEs, formats them and sends them to the FMP server for further processing]

Management Information Base [collection of object definitions in a virtual storage, specifies the management variables which are conceptually organized as a tree, with e.g. an (Internet containing) subtree like iso(1).org(3).dod(6).internet(1).mgmt(2).mib-2(1).system(1) or 1.3.6.1.private(4).enterprises(1).hp(11).nm(2).system(3).hpux(2) .hp9000s700(5), can be defined by standards bodies such as IETF MIB-II or by specific vendors as enterprise-specific MIB]

Next Hop Routing Protocol [allows routers to dynamically discover the data link address for other routers on a WAN cloud; particularly important for ATM, Frame Relay, SMDS and X.25 environments. Today it is necessary to configure the network layer and datalink layer address for all neighbors on a WAN cloud; NHRP enables the router to discover these addresses dynamically.]

It is well-suited to high-speed WAN transmission bursts. ATM currently accommodates transmission speeds from 64 Kbps to 622 Mbps. ATM may support gigabit speeds in the future.]

Digital European (or Enhanced) Cordless Telecommunications [2nd generation cordless telephone standard, designed to be capable of supporting very high traffic densities (up to basic rate ISDN) by 10 RF carriers * 12 duplex voice channels per carrier (=120 voice channels) per BTS, at 1895-1906 MHz (private) and 1906-1918 MHz (public), with a proposed extension to a 30 MHz frequency band, with TDMA/TDD access technique, GMSK modulation technique, making it suitable for low mobility-high capacity, vs GSM900, concentrated usage environments such as city center offices and transport hubs, developed in Europe, see also PHS]

Asynchronous Transfer Mode [base for future broadband ISDN, 53 Byte packets, current standards: SONET/SDH, DS3, TAXI and Fiber Channel system, user network interface has to support bandwidths of 155 Mbs or 600 Mbs. An international ISDN high-speed, high-volume, packet-switching transmission protocol standard. ATM uses short, uniform, 53-byte cells to divide data into efficient, manageable packets for ultrafast switching through a high-performance communications network.
