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.
A specific probability distribution function intended to model calling patterns of users who fail to find available facilities. Note: There are several blocking formulas. The applicability of each to a given situation depends on its underlying assumptions regarding caller behavior.
Industry:Telecommunications
A specific set of universal personal telecommunications service users.
Industry:Telecommunications
A specification that facilitates the management and development of consistent language-binding standards.
Industry:Telecommunications
A specified bit pattern that indicates the start of a transmission frame.
Industry:Telecommunications
A specified logical structure for a collection of data objects, including allowable ranges for their values and other data consistency specifications.
Industry:Telecommunications
A specified period of time during which bits are transferred from a source to a destination, where a bit error ratio worse than a specified threshold occurs. Severely errored units of time are excluded from the calculation. An example of a degraded unit of time is a degraded minute (DM. )
Industry:Telecommunications
A specified period of time, during which bits are transferred from a source to a destination, that contains at least one bit in error. Examples of an errored unit of time are an errored second (ES,) and a severely errored second.
Industry:Telecommunications
A spectral region in which the absorption coefficient reaches a relative maximum, by virtue of the physical properties of the matter in which the absorption process takes place.
Industry:Telecommunications
A spread spectrum system in which the RF carrier is modulated with a fixed period and fixed duty cycle sequence. Note: At the beginning of each transmitted pulse, the carrier frequency is frequency modulated which causes additional spreading of the carrier. The pattern of the frequency modulation depends upon the spreading function which is sweeping either up or down in frequency.
Industry:Telecommunications
A spurious pattern or other distortion in a facsimile record copy caused by unwanted modulation products arising from the transmission of a carrier signal, and appearing in the form of a rectified baseband that interferes with the lower sideband of the carrier. Note: The Kendall effect occurs principally when the single-sideband width is greater than half of the facsimile carrier frequency.
