In adaptive high-frequency (HF) radio, protection intended to prevent the establishment of unauthorized links or the unauthorized manipulation of legitimate links, and which are administered through an authorization process.
Industry:Telecommunications
In adaptive high-frequency (HF) radio, an automatic-link-establishment (ALE) call that requests responses from stations having connectivity to the destination specified in the call.
Industry:Telecommunications
In adaptive high-frequency (HF) radio, a bit error ratio derived by a majority decoder that processes redundant transmissions. Note: In adaptive HF radio automatic link establishment, PBER is determined by the extent of error correction, such as by using the fraction of non-unanimous votes in the 2-of-3 majority decoder.
Industry:Telecommunications
In adaptive high-frequency (HF) radio automatic link establishment, a broadcast in which (a) the called stations are unspecified, (b) stations receiving the call stop scanning, and (c) each station automatically responds in pseudorandom time slots.
Industry:Telecommunications
In adaptive high-frequency (HF) radio automatic link establishment (ALE,) a general broadcast that does not request responses and does not designate any specific addresses. Note: This essential function is required for emergencies ("HELP",) sounding-type data exchanges, and propagation and connectivity tracking.
Industry:Telecommunications
In acoustics, noise in which there is equal power per octave.
Industry:Telecommunications
In acoustics, a unit of subjective loudness level equal to the sound pressure level in dB compared to that of an equally loud standard sound. Note: The accepted standard is a 1-kHz pure sine-wave tone or narrowband noise centered at 1 kHz.
Industry:Telecommunications
In ac signaling, a signal consisting of the simultaneous transmission of more than one frequency. Note: An example of compound signaling is dual-tone multifrequency (DTMF) signaling.
Industry:Telecommunications
In ac power distribution, a device for sensing deviations of any measured variable, such as voltage, current, or frequency, and capable of initiating a programmed action, such as transfer to other power sources, when programmed limits of voltage, current, frequency, or time are exceeded, or providing an alarm, or both.
Industry:Telecommunications
In a wideband packet node, the point that receives channelized traffic, packetizes it, and sends it into the wideband packet network.
