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.
Multiplexing using close spectral spacing of individual optical carriers (wavelengths) to take advantage of desirable transmission characteristics (e.g., minimum dispersion or attenuation) within a given fiber, while reducing the total fiber count needed to provide a given amount of information-carrying capacity.
Industry:Telecommunications
Multipoint transmission in which (a) all the stations in a network are serially connected in one closed loop, (b) there are no cross-connections, (c) the stations serve as regenerative repeaters, forwarding messages around the loop until they arrive at their destination stations, and (d) any station can introduce a message into the loop by interleaving it with other messages.
Industry:Telecommunications
Mutual acceptance and exchange of messages between entities.

NANPA holds overall responsibility for the neutral administration of NANP numbering resources, subject to directives from regulatory authorities in the countries that share the NANP. NANPA's responsibilities include assignment of NANP resources, and, in the U. S. And its territories, coordination of area code relief planning and collection of utilization and forecast data.
Industry:Telecommunications
Narrowband analog-to-digital conversion that uses a one-level or multilevel sampling system in which the value of the signal at each sampling instant is predicted according to a linear function of the past values of the quantized signals. Note: APC is related to linear predictive coding (LPC) in that both use adaptive predictors. However, APC uses fewer prediction coefficients, thus requiring a higher sampling rate than LPC.
Industry:Telecommunications
National Security standards which must be observed by all Government Departments and List X companies so that they may pass information to each other with confidence that it will be handled with adequate care by all recipients. Note: minimum computer security standards are based on a risk assessment combined with an assessment of the value of assets to be protected.
Industry:Telecommunications
Network control in which the control station invites tributary stations to transmit in the sequence specified by the control station. 2. In point-to-point or multipoint communication, the process whereby stations are invited one at a time to transmit. 3. Sequential interrogation of devices for various purposes, such as avoiding contention, determining operational status, or determining readiness to send or receive data. 4. In automated HF radio systems, a technique for measuring and reporting channel quality.
Industry:Telecommunications
Network elements that originate and/or terminate line signals. LTEs can originate, access, modify, or terminate the transport overhead, or can perform any combination of these actions.
Industry:Telecommunications
Network equipment that provides functions necessary for network operation of ISDN access protocols. Note: Network termination provides functions essential for transmission services.
Industry:Telecommunications
Network management functions extended to include subscriber elements or user end instruments. 2. In computer systems, synonym system administration.
