A notch, i.e., a dip, in the noise frequency spectrum characteristic of a device, such as a transmitter, receiver, channel, or amplifier, from external sources or internal sources. Note: The noise window is usually represented as a band of lower amplitude noise in a wider band of higher amplitude noise.
Industry:Telecommunications
A number assigned by a service provider for its own internal business purposes. See "Administrative Numbers" definition.
Industry:Telecommunications
A number determined in accordance with the Code of Federal Regulations, Title 47, part 68, which number represents the ringer loading effect on a line. Note: A ringer equivalency number of 1 represents the loading effect of a single traditional telephone set ringing circuit. Modern telephone instruments may have a REN lower than 1. The total REN expresses the total loading effect of the subscriber's equipment on the central office ringing current generator. The service provider usually sets a limit, e. G. , 3, 4, or 5 (representing "extension," i.e., parallel-connected telephones,) to the total REN on a subscriber's loop. The actual number of instruments across the loop may be greater than the service provider's REN limit, if their respective individual RENs are less than 1.
Industry:Telecommunications
A number dialed by a UPT user to contact the service provider when using certain terminals and networks. In order to achieve its purpose, the UPTAN must contain information that can be used (a) to route the call to the user's service provider and (b) to specify the service profile. The UPTAN should be an E. 164 number.
Industry:Telecommunications
A number dynamically assigned on a per call basis by the serving wireless service provider to a roaming subscriber for the purpose of incoming call setup. See "Administrative Numbers" definition.
Industry:Telecommunications
A number selected from a known set of numbers in such a way that each number in the set has the same probability of occurrence. 2. A number obtained by chance. 3. One of a sequence of numbers considered appropriate for satisfying certain statistical tests or believed to be free from conditions that might bias the result of a calculation.
Industry:Telecommunications
A number that expresses the degree of electrical coupling that exists between two circuits. Note: The coupling coefficient is calculated as the ratio of the mutual impedance to the square root of the product of the self-impedances of the coupled circuits, all impedances being expressed in the same units.
Industry:Telecommunications
A number that identifies unambiguously a certain connection at the interface between the signaling connection control plan (SCCP) and a user function.
Industry:Telecommunications
A number that is expressed in binary notation and is usually characterized by the arrangement of bits in sequence, with the understanding that successive bits are interpreted as coefficients of successive powers of the base 2.
Industry:Telecommunications
A number that is used to identify a subnetwork so that IP addresses can be shared on a local area network.
