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 measurement of the depth of a body of water or the distance to an object in a body of water by measuring the time it takes sound or electromagnetic waves of known velocity to reflect from the bottom of the water body or from the distant object. Note: In echo sounding, damped cw transmission is usually used.
Industry:Telecommunications
The measure or extent of the ability of a system, such as a computer, communications, data processing, or weapons system, to continue to function despite the existence of faults in its component subsystems or parts. Note: System performance may be diminished or otherwise altered until the faults are corrected.
Industry:Telecommunications
The means of connecting one location to another for the purpose of transmitting and receiving data. 2. An assembly, consisting of parts of two data terminal equipments (DTEs) and the interconnecting data circuit, that is controlled by a link protocol enabling data to be transferred from a data source to a data sink.
Industry:Telecommunications
The means by which a cryptographic key is passed from its origination point to its point (s) of actual use, whether by bonded courier, registered mail, over-the-air-rekeying (OTAR,) or a number of other protected methods. Note: As a result of key transport, all rightful participants share a common secret key in such a way that the secret key is determined entirely by one party.
Industry:Telecommunications
The mean time to restore service following system failures that result in a service outage. Note: The time to restore includes all time from the occurrence of the failure until the restoral of service.
Industry:Telecommunications
The maximum variable transmission and processing delay that is permitted in a wideband network. Each PVP (packetized voice protocol) node records the delay that it adds and updates accordingly the TS (time stamp) value in the packet header. When the terminating endpoint of a PVP node receives a voice packet, the provisioned build-out and the time stamp value are compared. If the TS value is larger than the build-out, the PVP node drops the packet. If the delay is less than the provisioned build-out, the packet is delayed by the difference between the two values.
Industry:Telecommunications
The maximum traffic per unit of time that a given telecommunications system, subsystem, or device can carry under specified conditions.
Industry:Telecommunications
The maximum time interval between equally spaced samples of a signal that will enable the signal waveform to be completely determined. Note 1: The Nyquist interval is equal to the reciprocal of twice the highest frequency component of the sampled signal. Note 2: In practice, when analog signals are sampled for the purpose of digital transmission or other processing, the sampling rate must be more frequent than that defined by Nyquist's theorem, because of quantization error introduced by the digitizing process. The required sampling rate is determined by the accuracy of the digitizing process.
Industry:Telecommunications
The maximum system-permissible excursion of the video signal in the white direction.
