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.
The time interval between the instant of occurrence of a specified input condition to a system and the instant of completion of a specified operation. 2. In communications, computer, and information processing systems, the time interval between the instant a request for service is received from a user and the instant of final release of all facilities by the user or either of two users. 3. In communications systems conference calls, the time interval between the instant a request for service is received from one of a group of concurrent users and the instant all but one of the users have released all facilities.
Industry:Telecommunications
The value of a particular characteristic of a signal at a chosen instant.
Industry:Telecommunications
The source noise temperature in a two-port network or amplifier that will result in the same output noise power, when connected to a noise-free network or amplifier, as that of the actual network or amplifier connected to a noise-free source. Note: If F is the noise figure numeric and 290 K the standard noise temperature, then the effective noise temperature is given by Tn = 290 (F-1. )
Industry:Telecommunications
With respect to a given information system (IS) asset, a log of expired passwords, used primarily for automatic comparison with proposed new passwords. A password history is used to ensure that proposed new passwords were not used in the recent past, if ever, in connection with the IS asset in question. A password history may be limited to only a prescribed number of expired passwords (the usual case) with any overflow (i.e., the earliest) being discarded as new ones are added; or it may retain expired passwords only for a prescribed period of time; or both. A password history represents a tool that may be used to ensure that passwords are not repeated within a period of time that is deemed consistent with the sensitivity of the protected information system asset.
Industry:Telecommunications
The shifting of signal pulse transitions from their proper positions relative to the beginning of the start pulse. Note: The magnitude of the distortion is expressed in percent of a perfect unit pulse length. Synonym start-stop TTY distortion.
Industry:Telecommunications
The use of telemetry for the transmission from a space station of results of measurements made in a spacecraft, including those relating to the functioning of spacecraft.
Industry:Telecommunications
With respect to television or other video display technologies, the process of transforming from one standard frame rate to another, using an algorithm. Note: Standard display rates of 24, 25, 29. 97, 30, and 60 fps (frames per second) presently exist.
Industry:Telecommunications
To take some kind of assenting action to initiate computer bootup, e.g., to turn on the primary power (often referred to as initiating a cold bootup) or restart a powered-up computer (often referred to as initiating a hot bootup or hot reboot. )
Industry:Telecommunications
To examine sequentially, part by part. 2. To examine every reference in every entry in a file routinely as part of a retrieval scheme. 3. In radar, one complete rotation of the interrogating antenna. 4. In SONAR, to search 360° or a specific search sector by the use of phased array of transducers. 5. To sweep, i.e., rotate, a beam about a point or about an axis.
Industry:Telecommunications
Use of sophisticated signal recovery equipment in a laboratory environment to recover information from data storage media.
