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.
A modem whose modulated output signal has an essential frequency spectrum that is limited to that which can be wholly contained within, and faithfully transmitted through, a voice channel with a nominal 4-kHz bandwidth. Note: High frequency (HF) modems are limited to operation over a voice channel with a nominal 3-kHz bandwidth.
Industry:Telecommunications
A modified changeover procedure that is used whenever the normal changeover procedure cannot be used because of failure (s) in the signaling terminal equipment or inaccessibility between the two involved signaling points.
Industry:Telecommunications
A modified version of the phase-alternation-by-line (PAL) television signal standard (525 lines, 50 Hz, 220 V primary power,) used in Brazil.
Industry:Telecommunications
A modulator constructed so that the carrier is suppressed and any associated carrier noise is balanced out. Note 1: The balanced modulator output contains only the sidebands. Note 2: Balanced modulators are used in AM transmission systems.
Industry:Telecommunications
A modulator in which the modulation factor is different for the alternate half-cycles of the carrier. Synonym asymmetrical modulator.
Industry:Telecommunications
A modulator that consists of multilayered films of material of different optical characteristics, is capable of modulating transmitted light by using electro-optic, electro-acoustic, or magneto-optic effects to obtain signal modulation, and may be used as a component in integrated optical circuits.
Industry:Telecommunications
A module of a program that forms a logical entity or performs a unit function. Note: The most vulnerable portion of code in a secure operating system is a special case of a kernel.
Industry:Telecommunications
A molded, insulated plastic product in the form of a helix, used to contain or dress electrical wiring, e.g., to create a wiring harness from a number of insulated wires.
Industry:Telecommunications
A mounting, e. G. , for a directional antenna, in which slewing takes place in (a) the plane tangent to the surface of the Earth or other frame of reference and (b) elevation about, i.e., above or below, that plane. Synonym x-y mount.
