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 synchronous code in which five equal-length bits represent one character. Note 1: The Baudot code, which was developed circa 1880, has been replaced by the start-stop asynchronous International Alphabet No. 2 (IA No. 2. ) Note 2: IA No. 2 is not, and should not be identified as, the Baudot code. Note 3: The Baudot code has been widely used in teletypewriter systems.
Industry:Telecommunications
A synchronous system developed by the International Radio Consultative Committee (CCIR,) used to establish contact with a station or group of stations automatically by means of radio. The operational and technical characteristics of this system are contained in CCIR Recommendation 493. 2.
Industry:Telecommunications
A synchronous system providing for full-duplex, end-to-end transmission of digital data at the subrate data channel rates of 2. 4, 4. 8, 9. 6, 19. 2, 56 and 64 kb/s rates on dedicated private line and multipoint circuits.
Industry:Telecommunications
A system consisting of a computer, process control equipment, and possibly a process interface system. Note: The process interface system may be part of a special-purpose computer.
Industry:Telecommunications
A system containing the application processes that are the ultimate source and sink of user traffic. Note: The functions of an end system can be distributed among two or more processors or computers.
Industry:Telecommunications
A system employing an error-detecting code and so arranged that any signal detected as being in error is either deleted from the data delivered to the data sink, in some cases with an indication that such deletion has taken place, or delivered to the data sink together with an indication that the signal is in error.
Industry:Telecommunications
A system in which components are grouped, i.e., layered, in a hierarchical arrangement, such that lower layers provide functions and services that support the functions and services of higher layers. Note: Systems of ever-increasing complexity and capability can be built by adding or changing the layers to improve overall system capability while using the components that are still in place.
Industry:Telecommunications
A system in which events, such as signals, occur in synchronism. Note 1: An example of a synchronous system is one in which a transmitter and receiver operate with a fixed time relationship. Note 2: A second example is SONET, which may accommodate payload signals in channels that are clocked at submultiples of the carrier clocking rate.
Industry:Telecommunications
A system in which the functions of a human operator and a machine are integrated.
Industry:Telecommunications
A system of alternating current distribution for supplying the primaries of distribution transformers from the generating station or substation distribution buses.
