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 potential for electromagnetic radiation to affect adversely munitions or electroexplosive devices.
Industry:Telecommunications
The portion of the operational load required for communications, tactical operations, and ancillary equipment including necessary lighting, air-conditioning, or ventilation required for full continuity of communications.
Industry:Telecommunications
The portion of the electromagnetic spectrum in which the longest wavelength is just below the visible spectrum, extending from approximately 4 nm to approximately 400 nm. Note: Some authorities place the lower limit of uv at values between 1 and 40 nm, 1 nm being the upper wavelength limit of x-rays. The 400-nm limit is the lowest visible wavelength, i.e., the highest visible frequency, violet. See electromagnetic spectrum.
Industry:Telecommunications
The portion of the digital-to-analog conversion process that generates an analog signal value from the digital signal that resulted from analog encoding. Note: Further action is required to integrate these samples to obtain a continuous approximation of the original signal, because analog decoding does not smooth the signal.
Industry:Telecommunications
The portion of the analog-to-digital conversion process that samples an analog signal and creates a digital signal that represents the value of the sample. Note: Multiple samples are needed to digitize a waveform over a time interval.
Industry:Telecommunications
The portion of spectrum, between limiting frequencies (or, in the optical regime, limiting wavelengths,) that is transmitted with minimum relative loss or maximum relative gain. Note 1: The limiting frequencies are defined as those at which the relative intensity or power decreases to a specified fraction of the maximum intensity or power. This decrease in power is often specified to be the half-power points, i.e., 3 dB below the maximum power. Note 2: The difference between the limiting frequencies is called the bandwidth, and is expressed in hertz (in the optical regime, in nanometers or micrometers. )
Industry:Telecommunications
The portion of security testing in which the advertised features of a system are tested for correct operation.
Industry:Telecommunications
The portion of electronic jamming that is directed against communications circuits and systems. 2. The prevention of successful radio communications by the use of electromagnetic signals, i.e., the deliberate radiation, reradiation, or reflection of electromagnetic energy with the objective of impairing the effective use of electronic communications systems. Note: The aim of communications jamming is to prevent communications by electromagnetic means, or at least to degrade communications sufficiently to cause delays in transmission and reception. Jamming may be used in conjunction with deception to achieve an overall electronic-countermeasure (ECM) plan implementation.
Industry:Telecommunications
The Portion of a trusted computing base whose normal function is to control access between subjects and objects and whose correct operation is essential to the protection of data in the system.
Industry:Telecommunications
The portion of a transmission facility, including terminating points, between (a) a terminal network element (NE) and a regenerator (for example, a central office/remote terminal and customer location equipment such as a DTE) or (b) two regenerators. A terminating point is the point after signal regeneration at which performance monitoring is or may be done.
