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 software that provides the X. 500 directory service for a portion of the directory information base. Note: Generally, each DSA is responsible for the directory information for a single organization or organizational unit.
Industry:Telecommunications
The variation in signal amplitude produced by the interaction of two or more signal elements with different relative phases.
Industry:Telecommunications
The standard video-signal waveform, measured in IRE units.
Industry:Telecommunications
The signal attenuation that would result if all absorbing, diffracting, obstructing, refracting, scattering, and reflecting influences were sufficiently removed so as to have no effect on propagation. Note: Free-space loss is primarily caused by beam divergence, i.e., signal energy spreading over larger areas at increased distances from the source.
Industry:Telecommunications
The time interval between (a) the instant of keying off the local transmitter to stop transmitting and (b) the instant the local receiver output has increased to 90% of its steady-state value in response to an rf signal from a distant transmitter. Note 1: The rf signal from the distant transmitter must exist at the local receiver input prior to, or at the time of, keying off the local transmitter. Note 2: Receive-after-transmit time delay applies only to half-duplex operation.
Industry:Telecommunications
To separate the individual fibers or buffer tubes of a fiber-optic cable for the purpose of splicing or installing optical connectors. Synonyms fan out, furcate.
Industry:Telecommunications
The synchronization of two television signals at the vertical, horizontal, and chroma phase levels such that the signals may be cut, mixed, or cross-faded without noticeable roll, jump, or chroma shift. Note: Modern usage accomplishes this with a frame synchronizer/time base corrector, but it may also be accomplished by a closed loop method or an open loop method, the latter using a pair of rubidium clocks and a video delay line to maintain chroma lock.

The variation in signal amplitude produced by the interaction of two or more signal elements with different relative phases.
Industry:Telecommunications
The software that provides the X. 500 directory service for a portion of the directory information base. Note: Generally, each DSA is responsible for the directory information for a single organization or organizational unit.
Industry:Telecommunications
The structure of a video signal wherein the R', G', and B' signals are kept separate from one another or wherein luminance and two bandlimited color-difference signals are kept separate from one another. Note: The separation may be achieved by separate channels, or by time-division multiplexing, or by a combination of both.
