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.
In network management, a complex that (a) is controlled by a customer and (b) is responsible for, and performs, maintenance for the customer installation.
Industry:Telecommunications
In network management, (a) a set of functions that evaluate and report the behavior of telecommunications equipment and the effectiveness of the network or network element and (b) a set of various subfunctions, such as gathering statistical information, maintaining and examining historical logs, determining system performance under natural and artificial conditions, and altering system modes of operation.
Industry:Telecommunications
In narrowband radio, the nominal 3-kHz bandwidth allocated for single channel radio that provides a transmission path for analog and quasi-analog signals.
Industry:Telecommunications
In multimode fiber optics, a technique used to modify the modal distribution of a propagating optical signal. Note: A cylindrical rod wrap consists of a specified number turns of fiber on a mandrel of specified size, depending on the fiber characteristics and the desired modal distribution. It has application in optical transmission performance tests, to simulate, i.e., establish, equilibrium mode distribution in a launch fiber (a fiber used to inject a test signal in another fiber that is under test. ) If the launch fiber is fully filled ahead of the mandrel wrap, the higher-order modes will be stripped off, leaving only lower-order modes. If the launch fiber is underfilled, e. G. , as a consequence of being energized by a laser diode or edge-emitting LED, there will be a redistribution to higher-order modes until modal equilibrium is reached.
Industry:Telecommunications
In multimedia and virtual reality, information that may be used to select a video source, and then control the video source to provide the desired view. The ability to provide presets is optional and may not be supported in all terminals.
Industry:Telecommunications
In multilevel precedence and preemption, the call receiver, i.e., the destination user, to which a precedence call will be diverted. Note 1: Diversion will occur when the response timer expires, when the call receiver is busy on a call of equal or higher precedence, or when the call receiver is busy with access resources that are non-preemptable. Note 2: Alternate party diversion is an optional terminating feature that is subscribed to by the call receiver. Thus, the alternate party is specified by the call receiver at the time of subscription.
Industry:Telecommunications
In multichannel telephone systems, a plot, for the busy hour, of the equivalent mean power and the peak power as a function of the number of voice channels. Note: The equivalent power of a multichannel signal referred to the zero transmission level point is a function of the number of channels and has for its basis a specified voice channel mean power.
Industry:Telecommunications
In multichannel switched networks, a method of transmitting all signaling information for a group of trunks by encoding it and transmitting it over a separate channel using time-division digital techniques.
Industry:Telecommunications
In motion picture or television production or editing, an abrupt change from one scene to another.
Industry:Telecommunications
In military telephone systems, a distinctive tone that is used to indicate to connected users, i.e., subscribers, that their call has been preempted by a call of higher precedence. Note: An example of preemption tone is a distinctive, steady, high-pitch tone transmitted for three seconds or until the preempted user hangs up.
