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 bulk encryption device used to provide secure communications over a wideband digital transmission link. Note: A TED is usually located between the output of a trunk group multiplexer and a wideband radio or cable facility.
Industry:Telecommunications
A building (such as a central office) or nonbuilding location housing NEs. Communication within an NE location may be accomplished with minimal attention to such factors as noise, lightning protection, or the cost of bandwidth; communication outside an NE location uses suitable modems and uses conventional communications services or an EOC (embedded operations channel. )
Industry:Telecommunications
A buffer, smaller and faster than main storage, used to hold a copy of instructions and data in main storage that are likely to be needed next by the processor and that have been obtained automatically from main storage.
Industry:Telecommunications
A buffer into which data may be entered at one rate and removed at another rate without changing the data sequence. Note: Most first-in first-out (FIFO) storage devices are variable-length buffers in that the input rate may be variable while the output rate is constant or the output rate may be variable while the input rate is constant. Various clocking and control systems are used to allow control of underflow or overflow conditions.
Industry:Telecommunications
A broadcast service that permits the licensing of 50- to 100-watt FM radio stations within a service radius of up to 3. 5 miles and 1- to 10-watt FM radio stations within a service radius of 1 to 2 miles.
Industry:Telecommunications
A broadcast service that permits program broadcasting via television translators operating with low power. LPTV service includes the existing translator service and operates on a secondary basis to regular television stations. Transmitter output is limited to 1,000 watts for normal VHF stations and 100 watts when a VHF operation is on an allocated channel.
Industry:Telecommunications
A broadband, multi-element, unidirectional, narrow-beam antenna that has impedance and radiation characteristics that are regularly repetitive as a logarithmic function of the excitation frequency. Note: The length and spacing of the elements of a log-periodic antenna increase logarithmically from one end to the other. Synonym log-periodic array.
Industry:Telecommunications
A broadband communications technology in which multiple television channels, as well as audio and data signals, may be transmitted either one way or bidirectionally through an often hybrid (fiber and coaxial) distribution system to a single or to multiple specific locations. CATV originated in areas where good reception of direct broadcast TV was not possible. Now CATV also consists of a cable distribution system to large metropolitan areas in competition with direct broadcasting. The abbreviation CATV originally meant community antenna television. However, CATV is now usually understood to mean cable TV.
Industry:Telecommunications
A bond not expected to require disassembly for operational or maintenance purposes.
Industry:Telecommunications
A body which revolves around another body of preponderant mass and which has a motion primarily and permanently determined by the force of attraction of that other body. Note: A parent body and its satellite revolve about their common center of gravity.
