Alarm indication signal; a signal transmitted in lieu of the normal signal to maintain transmission continuity, and indicates to the receiving terminal that there is a transmission fault located upstream or at the transmitting terminal
In T1, an all ones condition used to alert a receiver that its incoming signal (or frame) has been lost. The loss of signal or frame is detected at the receiving end, and the failed signal is replaced by all the ones condition which the receiver interprets as an AIS. The normal response to this is AIS is for the receiving end to generate a yellow alarm signal as part of its transmission towards the faulty end. (The AIS itself is sometimes called a Blue Signal).
Administrative Information System. Used throughout the North Dakota University System for business and student records functions of each campus. The system is administered and maintained by the Higher Education Computer Network (HECN) staff and is hosted at the University of North Dakota in Grand Forks. http://www.nodak.edu/hecn
(Aeronautical Information Service) Central office providing information and advice to flight crews, airlines and general aviation. Receives data (â€“ dynamic data / static data) necessary to ensure the safe and orderly flow of traffic, and processes and transmits such data. Examples include airspace restrictions, weather information, NOTAM (â€“), overflight or approach clearance, etc. Advises the flight crew or airline before the flight and assists both air traffic control and pertinent ground services. Skyguide operates an AIS at Zurich Airport, and four AROs (â€“) at the Bern, Geneva, Lugano et Zurich Airports.
Automated Identification System. an electronic instrument placed on regulated powered vessels to automatically provide their identity, location and other navigational data to a central receiving base to facilitate navigational control and safety.
AUTOMATED INFORMATION SYSTEM. An information system that usually involves the use of a computer. Often used as a synonym for an electronic records system. See also COMPUTER SYSTEM, ELECTRONIC RECORDS SYSTEM, INFORMATION SYSTEM.
AUTOMATED INFORMATION SYSTEM. Computer hardware, computer software, telecommunications, information technology, personnel, and other resources that collect, record, process, store, communicate, retrieve, and display information. An AIS can include computer software only, computer hardware only, or a combination of the above (See DoD Directive 8000.1, reference (d).)
alarm indication signal. In a T1 transmission, an all-ones signal is transmitted in lieu of the normal signal. This signal maintains transmission continuity, and indicates to the receiving terminal that a transmission fault is located either at, or upstream from, the transmitting terminal.
Automated Information System - any equipment of an interconnected system or subsystems of equipment that is used in the automatic acquisition, storage, manipulation, control, display, transmission, or reception of data and includes software, firmware, and hardware.
Automated Information System. An assembly of computer hardware, firmware, and software configured to collect, create, communicate, compute, disseminate, process, store, and /or control data or information.
Automatic Identification System. A system onboard a ship that continuously transmit the vessel's identification, position, course, speed as well as other data to other ships and relevant authorities. Synonym: universal automatic identification system (UAIS).
Administrative Information Services. Serves as the central University resource responsible for supporting administrative information systems. As a unit of Information Technology Services (ITS), AIS participates in the development, maintenance, and secure operation of the state-of-the-art applications using centralized student, business, and alumni databases.
Automated information system. Computer hardware and software configured to automate calculating, computing, sequencing, storing, retrieving, displaying, communicating, or otherwise manipulating data and textual material to provide information.
The Ais, or Ays were a tribe of Native Americans who inhabited the Atlantic Coast of Florida. They ranged from present day Cape Canaveral to the St. Lucie River Inlet, in the present day counties of Brevard, Indian River, and St.
ddress nformation ystems - Also known as Address Management; an organizational unit that provides USPS policy and systems on address list serviced, address correction, forwarding, and other ancillary services.
Automatic Investment Service. A service offered to mutual fund shareholders that allows a shareholder to automatically invest sums of money into a fund. This type of plan does not assure a profit and does not protect against loss in declining markets.
Adaptive Instructional Software. 1] - Software that self-adapts in real-time to the data available. The software continuously analyzes individual student's responses, and adjusts (guides) the instructional process accordingly. Adaptive Networks (AN) or Neural Networks (NN) are new technologies that may be able to accomplish this in practice.
