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 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 signaling mode in which messages involving two (nonadjacent) signaling points are communicated between them over two or more signaling links in tandem passing through one or more signaling transfer points other than those which are the origin and destination of the messages.
Industry:Telecommunications
Three-dimensional space surrounding information-system (IS) equipment, within which unauthorized persons are denied unrestricted access and are either escorted by authorized persons or are under continuous physical or electronic surveillance. Synonym restricted area.
Industry:Telecommunications
The use of computers and associated application software to compose, lay out, model, and develop prototypes of documents that are usually intended to be produced and distributed in some non-interactive medium, usually paper, but including film or other multimedia formats. Note: Unlike electronic publishing, desktop publishing almost always results in some form of hard copy.
Industry:Telecommunications
The width of a frequency band such that, below the lower and above the upper frequency limits, the mean powers emitted are each equal to a specified percentage B/2 of the total mean power of a given emission. Unless otherwise specified by the CCIR for the appropriate class of emission, the value of B/2 should be taken as 0. 5%. Note 1: The percentage of the total power outside the occupied bandwidth is represented by B. Note 2: In some cases, e.g., multichannel frequency-division multiplexing systems, use of the 0. 5% limits may lead to certain difficulties in the practical application of the definition of occupied and necessary bandwidth; in such cases, a different percentage may prove useful. 2. The frequency bandwidth such that, below its lower and above its upper frequency limits, the mean powers radiated are each equal to 0. 5% of the total mean power radiated by a given emission.
Industry:Telecommunications
Traffic that is recorded, in permanent or quasipermanent form, by the originator, the addressee, or both. 2. Traffic that is permanently or semipermanently recorded in response to administrative procedures or public law.
Industry:Telecommunications
The time interval between the instant at which a valid frame-alignment signal is available at the receiving data terminal equipment and the instant at which frame alignment is established. Note: The reframing time includes the time required for replicated verification of the validity of the frame-alignment signal. Synonym frame-alignment recovery time.
Industry:Telecommunications
The time in milliseconds (ms) between the incidence of a signal and the incidence of that signal's echo at a measurement point.
Industry:Telecommunications
To send information from one location and to receive it at another.
Industry:Telecommunications
To preempt, manually or automatically, a prescribed procedure. Note: For example, one might manually override a prescribed course of action programmed to occur in the event of a fault. 2. In telephony, the entering of or seizure of, a busy circuit, i.e., an occupied circuit, by a party other than those using the circuit. Note: For example, an attendant might override a circuit after a busy verification, or a user with a higher precedence level might override a circuit.
