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.
In spread-spectrum systems, the duration of a chip produced by a frequency-hopping signal generator.
Industry:Telecommunications
In start-stop modulation, the maximum amount of overall start-stop distortion that is compatible with correct translation by the start-stop equipment of all the character signals that appear singly, that appear at the maximum allowable speed, or that appear at the standard modulation rate.
Industry:Telecommunications
In start-stop modulation, the ratio of (a) the maximum absolute difference between the actual and the theoretical intervals that separate any significant instant of modulation or demodulation from the significant instant of the start signal element immediately preceding it to (b) the unit interval.

In start-stop teletypewriter operation, the shifting of the end of all marking pulses, except the stop pulse, from their proper positions in relation to the beginning of the next start pulse. Note 1: Shifting of the end of the stop pulse is a deviation in character time and rate rather than an end distortion. Note 2: Spacing end distortion is the termination of marking pulses before the proper time. Note 3: Marking end distortion is the continuation of marking pulses past the proper time. Note 4: The magnitude of the distortion is expressed as a percentage of an ideal pulse length.

In start-stop transmission, a signal at the end of a character that prepares the receiving device for the reception of a subsequent character. A stop signal is usually limited to one signal element having any duration equal to or greater than a specified minimum value. 2. A signal to a receiving mechanism to wait for the next signal.

In statistics, in a population of samples, the mean of the squares of the differences between the respective samples and their mean, expressed mathematically as: where n is the number of samples, xi is the value of sample i, is the mean of the samples, and 2 is the variance. Note: The square root of the variance, , is the standard deviation.
Industry:Telecommunications
In studies of network survivability in an earthquake, the ratio of actual damping to critical damping.
Industry:Telecommunications
In switching systems, the point where user traffic enters and exits a communications network. Note: Access node operations may include various operations, such as protocol conversion and code conversion.
