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 system that handles more than one media stream in a synchronized way from the user's point of view. The system may allow interconnection of multiple parties, multiple connections, and the addition or deletion of resources and users within a single communication session.
Industry:Telecommunications
A system that has a means of monitoring its own performance, a means of varying its own parameters, and uses closed-loop action to improve its performance or to optimize traffic.
Industry:Telecommunications
A system that monitors a pilot for interruptions on frequency division multiplexing (FDM) systems and that transmits an indication to the switching equipment.
Industry:Telecommunications
A system that performs operations system functions (OSFs,) that is, supports the processing of information related to operations, administration, maintenance, and provisioning for the telecommunications networks. Note: An operations system performs surveillance and testing functions to support customer access maintenance.
Industry:Telecommunications
A system that provides a means for telecommunications users to obtain priority treatment from service providers for the NS/EP telecommunications requirements. Note: The TSP system replaced the Restoration Priority (RP) system effective September 1990.
Industry:Telecommunications
A system that provides an Open Systems Interconnection--Reference Model (OSI--RM) Network Layer relay function in which data received from one corresponding network entity are forwarded to another corresponding network entity.
Industry:Telecommunications
A system using electromagnetic transmissions to which equipment carried by friendly forces automatically responds, for example, by emitting pulses, thereby distinguishing themselves from enemy forces. Note: The secondary surveillance radar (SSR) system used in modern air traffic control systems is an outgrowth of the military IFF system used during World War II. The IFF equipment carried by modern military aircraft is compatible with the transponder system used for civilian air traffic control.
Industry:Telecommunications
A system, whether automated or manual, that comprises people, machines, and/or methods organized to collect, process, transmit, and disseminate data that represent user information. 2. Any telecommunications and/or computer related equipment or interconnected system or subsystems of equipment that is used in the acquisition, storage, manipulation, management, movement, control, display, switching, interchange, transmission, or reception of voice and/or data, and includes software, firmware, and hardware. 3. The entire infrastructure, organization, personnel, and components for the collection, processing, storage, transmission, display, dissemination, and disposition of information.
Industry:Telecommunications
A systematic and comprehensive framework that a) consists of the ingredients that make up communications infrastructure, b) includes all of these ingredients, c) specifies the 8 ingredients of environment, power, hardware, software, network, payload, ASPR (Agreements, Standards Policy and Regulations; abbreviated as Policy) and human. This framework is used for understanding and mastering vulnerabilities, identifying disciplines, decomposing attributes, preparing for new technologies, and other studies that support network, security, and emergency preparedness. The Eight Ingredient Framework was first introduced by Bell Labs during the April 2001 IEEE CQR International workshop (Proceedings of 2001 IEEE Communications Society Technical Committee Communications Quality & Reliability (CQR) International Workshop, www. Comsoc. Org/~cqr,) and has since been foundational in several critical analyses, including the following: a systematic list of factors influencing network reliability published in the ATIS Network Reliability Steering Committee (NRSC) 2002 Annual Report (www. Atis. Org/nrsc); Best Practice development based on systematic vulnerability analysis published in the Federal Communications Commission (FCC) Network Reliability and Interoperability Council (NRIC) VI Homeland Security Physical Security Focus Group Final Report, Issue 3, December 2003, NRIC VII Wireless Network Reliability Focus Group Final Report, Issue 3, October 2005, NRIC VII Public Data Network Reliability Focus Group, Issue 3, October 2005 (www. Nric. Org); a systematic analysis of vulnerabilities of next generation networks in the President's National Security Telecommunications Advisory Committee (NSTAC) Next Generation Networks Task Force Final Report, March 2006, and as a basis for post-9-11 proactive infrastructure protection published in "Protecting Communications Infrastructure", Bell Labs Technical Journal Homeland Security Special Issue, Volume 9, Number 2, 2004.
Industry:Telecommunications
A systematic deviation of a value from a reference value. 2. The amount by which the average of a set of values departs from a reference value. 3. Electrical, mechanical, magnetic, or other force (field) applied to a device to establish a reference level to operate the device. 4. In telegraph signaling systems, the development of a positive or negative dc voltage at a point on a line that should remain at a specified reference level, such as zero. Note: A bias may be applied or produced by (i) the electrical characteristics of the line, (ii) the terminal equipment, and (iii) the signaling scheme.
