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 loopback in which the signal transmitted beyond the loopback point (the forward signal) when the loopback is activated, is not the same as the received signal at the loopback point. The forward signal may be a defined signal or unspecified.
Industry:Telecommunications
A loop-open signal of 300 to 1000 ms at the network interface (NI) that is generated by the network, typically under the control of the far-end customer interface (CI,) to control supplementary calling features when such features are provided by the near-end CI.
Industry:Telecommunications
A loss of optical power that occurs at a splice or a pair of mated connectors when the numerical aperture of the "transmitting" fiber exceeds that of the "receiving" fiber, even if the cores are precisely the same diameter and are perfectly aligned. Note 1: The higher numerical aperture of the transmitting fiber means that it emits a larger cone of light than the receiving fiber is capable of accepting, resulting in a coupling loss. Note 2: In the opposite case of numerical aperture mismatch, where the transmitting fiber has the lower numerical aperture, no numerical aperture loss occurs, because the receiving fiber is capable of accepting light from any bound mode of the transmitting fiber.
Industry:Telecommunications
A low-pass filter used to reduce unwanted higher frequencies.
Industry:Telecommunications
A low-pass filter with a steep cut-off (such as 20 dB/octave or greater,) such that a negligible amount of higher frequency information passes. Note: A brick wall filter typically has uniform group delay.
Industry:Telecommunications
A low-power, short-range, rf technology that allows the connection of intelligent communications devices or appliances in a household or an office in a short-range wireless network. Examples of Bluetooth applications are transferring data between cell phones, radios, pagers, personal digital assistants, notebook computers, video and still cameras, audio players, and local area networks.
Industry:Telecommunications
A low-powered mobile station in the maritime mobile service intended for use for internal communications on board a ship, or between a ship and its lifeboats and liferafts during lifeboat drills or operations, or for communication within a group of vessels being towed or pushed, as well as for line handling and mooring instructions.
Industry:Telecommunications
A low-resolution video display standard, having a pixel resolution of 320 x 200.
Industry:Telecommunications
A machine function or series of machine functions controlled by a program and carried out without assistance of an operator.
Industry:Telecommunications
A machine that uses typed input and output, usually with a visual text display, to enable individuals with hearing or speech impairments to communicate over a telecommunications network.
