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 connection between the radio port controller and the PCS (personal communications services) switching center.
Industry:Telecommunications
The configuration of a field composed of an integral number of octets. Note: If the field is not divisible by eight, bits (usually zeros) are added to either the first octet (left justification) or the last octet (right justification. )
Industry:Telecommunications
The confidence that the compromise of a long-term private key does not compromise any earlier session keys.
Industry:Telecommunications
The condition where information flow is provided only in one direction.
Industry:Telecommunications
The condition that prevails when the numerical aperture of an optical source, such as a laser, light-emitting diode, or optical fiber, exceeds that of the driven element, e.g., optical fiber core. 2. The condition that prevails when the beam diameter of an optical source, such as a laser, light-emitting diode, or optical fiber, exceeds that of the driven element, e.g., optical fiber core. Note: In optical communications testing, overfill in both numerical aperture and mean diameter (core diameter or spot size) is usually required.
Industry:Telecommunications
The condition that prevails when the instantaneous level of the modulating signal exceeds the value necessary to produce 100% modulation of the carrier. Note 1: Overmodulation results in spurious emissions by the modulated carrier, and distortion of the recovered modulating signal. Note 2: Overmodulation in the sense of this definition is almost always considered a fault condition. 2. The condition that prevails when the mean level of the modulating signal is such that peaks in the modulating signal exceed the value necessary to produce 100% modulation of the carrier. Note: Overmodulation in the sense of this definition, if not excessive, is sometimes considered permissible.
Industry:Telecommunications
The condition that prevails when attenuation, rather than bandwidth, limits the performance of a communications link.
Industry:Telecommunications
The condition that occurs when, in both-way operation, two exchanges attempt to seize the same circuit at approximately the same time. Synonyms call collision, glare.
Industry:Telecommunications
The condition that occurs when an earlier nonactive speaker on an input transmission trunk channel becomes active and cannot immediately be assigned to a bearer channel, due to lack of free instantaneous transmission capacity.
Industry:Telecommunications
The condition that exists when one or more of the required service performance parameters fall outside predetermined limits, resulting in a lower quality of service. Note: A degraded service state is considered to exist when a specified level of degradation persists for a specified period of time.
