A noise spectral weighting used in a noise power measuring set to measure noise power on a line that is terminated by a 500-type set or similar instrument. Note: The instrument is calibrated in dBrnC.
Industry:Telecommunications
A noise weighting established by the International Consultative Committee for Telephony (CCIF, which became CCITT and, more recently, ITU-T,) designated as CCIF-1951 weighting, for use in a noise measuring set or psophometer. Note: The shape of this characteristic is virtually identical to that of F1A weighting. The psophometer is, however, calibrated with a tone of 800 Hz, 0 dBm, so that the corresponding voltage across 600 ohms produces a reading of 0. 775 V. This introduces a 1-dBm adjustment in the formulas for conversion with dBa.
Industry:Telecommunications
A noise weighting used in a noise measuring set to measure noise across the HA1-receiver of a 302-type or similar instrument. Note 1: The meter scale readings of an HA1 test set are in dBa (HA1. ) Note 2: HA1 noise weighting is obsolete for new DOD applications.
Industry:Telecommunications
A noncommunications metallic cable component such as a shield, vapor barrier, or strength member.
Industry:Telecommunications
A nongovernmental, international organization for global cooperation and coordination for The Internet and its internetworking technologies and applications.
Industry:Telecommunications
A nonhierarchical grouping of sensitive information used to control access to data more finely than with hierarchical security classification alone.
Industry:Telecommunications
A nonhostile environment that may be protected from external hostile elements by physical, personnel, and procedural security countermeasures.
Industry:Telecommunications
A nonlinear analog device that has a lower gain at higher input levels than at lower input levels. Note: A compressor is used to allow signals with a large dynamic range to be sent through devices or circuits with a smaller dynamic range.
Industry:Telecommunications
A nonpermanent display image, for example, a cathode ray tube display.
Industry:Telecommunications
A non-secret value that uniquely identifies a key set.
