Operation in which one or more channels of a multichannel system are terminated, i.e., dropped, at an intermediate point between the end terminals of the system.
Industry:Telecommunications
Operation in which speech and telegraphy (duplex or simplex) are transmitted simultaneously over the same circuit, and mutual interference is eliminated by the use of filters.
Industry:Telecommunications
Operation in which transmission occurs in one and only one preassigned direction. Synonym one-way operation. Note: Duplex operation may be achieved by simplex operation of two or more simplex circuits or channels. 2. Operating method in which transmission is made possible alternately in each direction of a telecommunication channel, for example by means of manual control. Note: In general, duplex operation and semiduplex operation require two frequencies in radiocommunication; simplex operation may use either one or two. Note 2: These two definitions are contradictory, however, both are in common use. The first one is used in telephony and the second one is used in radio. The user is cautioned to verify the nature of the service specified by this term.

Industry:Telecommunications
Operation of a communication network in which transmission may occur between the control station and any tributary station, but not between tributary stations.
Industry:Telecommunications
Operation of a communications link in which signal waveform degradation attributable to the dispersive effects of the communications medium is the dominant mechanism that limits link performance. Note 1: The amount of allowable degradation is dependent on the quality of the receiver. Note 2: In fiber optic communications, "dispersion-limited operation" is often confused with "distortion-limited operation. "
Industry:Telecommunications
Operation of a communications system with sufficient phase-locking to avoid overflowing or emptying buffers.
Industry:Telecommunications
Operation of a dc system with the battery, rectifier, and load all connected in parallel. The battery charger supplies the normal dc load plus any battery self-discharge current or recharge current required after a discharge.
Industry:Telecommunications
Operation of data circuit-terminating equipment (DCE) so that circuitry, such as data terminal equipment (DTE,) associated with call origination is directly connected to a communications channel.
Industry:Telecommunications
Operation of equipment or appliances designed to generate and use locally radio-frequency energy for industrial, scientific, medical, domestic or similar purposes, excluding applications in the field of telecommunications.
