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 special federal government telecommunications service that provides National Security and Emergency Preparedness (NS/EP) users with priority switched voice and voiceband data communications during periods of emergency or crisis. GETS uses existing features and services of the Public Switched Network (PSN) with selected NS/EP augmentations and enhancements. Access to GETS requires a telephone calling card with personal identification number. GETS is maintained in a constant state of readiness to make maximum use of all available PSN telephone resources should network congestion or damage occur during an emergency or crisis. GETS calls receive priority over other traffic through special features such as trunk queuing, exemption from restrictive network management controls and Alternate Carrier Routing (ACR) on approximately 85% of all local carrier access lines. Comparable features provide priority treatment and enhanced routing in the interexchange networks. While GETS calls receive priority for next available path, they do not preempt other traffic. The Signaling System No. 7 (SS7) - High Probability of Completion (HPC) Network Capability standard (ANSI T1. 631-1993) is applied to provide NS/EP call identification and priority signaling.
Industry:Telecommunications
A special sequence that indicates that no data are being sent on the channelized side.
Industry:Telecommunications
A specialized form of coaxial cable, circular in cross-section and consisting of (a) a center conductor, often a solid wire but sometimes braided; separated by an insulating material from (b) a concentric solid or braided conductor which is in turn separated by an insulating material from (c) a third solid or braided conductor, concentric with the first two; and (d) a protective sheath.
Industry:Telecommunications
A specialized operating system designed for computer networking on minicomputers and microcomputers in a local networking area / campus area network. Note: A NOS is usually designed to run on existing software designed for that computer and may require interface hardware for the workstation and server.
Industry:Telecommunications
A specialized program that facilitates information retrieval from large segments of the Internet. Note 1: Search engines attempt to help a user locate desired information or resources by seeking matches to user-specified key words. The usual method for finding and isolating this information is to compile and maintain an index of Web resources that can be queried for the key words or concepts entered by the user. The indices are often built from specific resource lists, and may also be created from the output of Web crawlers, wanderers, robots, spiders, or worms. The indices are usually compiled during times of minimum network traffic. Note 2: Different engines are appropriate for different kinds of searches, and most can be optimized for specified results.
Industry:Telecommunications
A specialized, programmable computer processing unit that is able to perform high-speed mathematical processing. Note: A DSP is ideal for use in compression algorithms.
Industry:Telecommunications
A specific amplitude-vs. -frequency characteristic that permits a measuring set to give numerical readings that approximate the interfering effects to any listener using a particular class of telephone instrument. Note 1: Noise weighting measurements are made in lines terminated either by the measuring set or the class of instrument. Note 2: The most widely used noise weightings were established by agencies concerned with public telephone service, and are based on characteristics of specific commercial telephone instruments, representing successive stages of technological development. The coding of commercial apparatus appears in the nomenclature of certain weightings. The same weighting nomenclature and units are used in military versions of commercial noise measuring sets.
