ATIS is the leading technical planning and standards development organization committed to the rapid development of global, market-driven standards for the information, entertainment and communications industry.
A station located either on the Earth's surface or within the major portion of the Earth's atmosphere and intended for communication:with one or more space stations; or with one or more stations of the same kind by means of one or more reflecting satellites or other objects in space.
Industry:Telecommunications
A station located on an object which is beyond, is intended to go beyond, or has been beyond, the major portion of the Earth's atmosphere.
Industry:Telecommunications
A station or address designator represented by a combination of characters or pronounceable words that is used to identify such entities as a communications facility, station, command, authority, activity, or unit.
Industry:Telecommunications
A station or address designator, used to represent a set of specific and frequently recurring combinations of action or information addresses. Note: The identity of the message originator may also be included in the AIG. An address group is assigned to each AIG for use as an address designator.
Industry:Telecommunications
A station utilizing radio waves in experiments with a view to the development of science or technique. This definition does not include amateur stations.
Industry:Telecommunications
A station which is transferred to various fixed locations but is not intended to be used while in motion.
Industry:Telecommunications
A statistically multiplexed interface protocol for packet switched data communications that uses fixed-length packets, i.e., cells, to transport data. Note 1: Cell relay transmission rates usually are between 56 kb/s and 1. 544 Mb/s, i.e., the data rate of a DS1 signal. Note 2: Cell relay protocols (a) have neither flow control nor error correction capability, (b) are information-content independent, and (c) correspond only to layers one and two of the ISO Open Systems Interconnection--Reference Model. Note 3: Cell relay systems enclose variable-length user packets in fixed-length packets, i.e., cells, that add addressing and verification information. Frame length is fixed in hardware, based on time delay and user packet-length considerations. One user data message may be segmented over many cells. Note 4: Cell relay is an implementation of fast packet technology that is used in (a) connection-oriented broadband integrated services digital networks (B-ISDN) and (b) connectionless IEEE 802. 6, switched multi-megabit data service (SMDS. ) Note 5: Cell relay is used for time-sensitive traffic such as voice and video.
Industry:Telecommunications
A statutory exemption pertaining to the acquisition of telecommunications systems that meet the exclusionary criteria of the Warner Amendment, Public Law 97-86, 1 December 1981, which is also known as the Brooks Bill. Note: Use of FTS2000 by U. S. Government agencies is mandatory when telecommunications are required. However, the Warner Amendment excludes the mandatory use of FTS2000 in instances related to maximum security.
Industry:Telecommunications
A still image transmitted in the ANSI Tl. 314 video stream encoded to the same resolution as the previous motion video (i.e., QCIF—quarter common intermediate format. ) Note: This mode uses a bit 2 "document camera indicator. "
Industry:Telecommunications
A still image transmitted in the standardized video stream encoded to twice the horizontal and twice the vertical resolution as the previous motion video (i.e., full common intermediate format (FCIF) or 4*FCIF. ) This mode uses bit 5 "Hi-Res" bit.
