A logical channel that provides a signaling path within an information channel or within a physical signaling channel.
Industry:Telecommunications
A logical connection that is made to a virtual circuit.
Industry:Telecommunications
A login that allows a user terminal to connect to a host computer via a network or direct telecommunications link, and to interact with that host computer as if the user terminal were directly connected to that host computer. Synonym remote logon.

Industry:Telecommunications
A long distance radionavigation land station transmitting synchronized pulses. Hyperbolic lines of position are determined by the measurement of the difference in the time of arrival of these pulses.
Industry:Telecommunications
A longitudinal wave that (a) consists of a sequence of pressure pulses or elastic displacements of the material, whether gas, liquid, or solid, in which the wave propagates, (b) in gases, consists of a sequence of compressions (dense gas) and rarefactions (less dense gas) that travel through the gas, (c) in liquids, consists of a sequence of combined elastic deformation and compression waves that travel though the liquid, and (d) in solids, consists of a sequence of elastic compression and expansion waves that travel though the solid. Note 1: The speed of an acoustic wave in a material medium is determined by the temperature, pressure, and elastic properties of the medium. In air, acoustic waves propagate at 332 m/s (1087 ft/s) at 0°C, at sea level. In air, sound-wave speed increases approximately 0. 6 m/s (2 ft/s) for each kelvin above 0°C. Note 2: Acoustic waves audible to the normal human ear are termed sound waves.

Industry:Telecommunications
A long-range radio navigation position-fixing system consisting of an array of fixed stations that transmit precisely synchronized signals to mobile receivers. Note: A loran receiver measures differences in the times of arrival of the signals from the various stations. A fixed difference in the time of arrival of the signals from any two stations will define a hyperbolic arc on which the receiver must lie. Three or more stations are needed to remove ambiguities in the position of the receiver. Synonyms long-range aid to navigation system, long-range radio aid to navigation system.
Industry:Telecommunications
A loop that has conditioning equipment to obtain the desired line characteristics for voice or data transmission. Note: The conditioning equipment is used to improve the amplitude-vs. -frequency characteristics of the circuit and to match impedance.
Industry:Telecommunications
A loopback in which the signal is transmitted beyond the loopback point (the forward signal. )
