A physical medium for transferring electrical or electromagnetic energy from one point to another for purposes of communications. 2. A land line. 3. A metallic medium used for the transmission of electrical power. 4. A transmission medium, together with the associated equipment, required to provide the means of transporting information between two consecutive network elements, one of which originates the line signal and the other terminates the line signal. 5. Synonym scanning line.
Industry:Telecommunications
A physical or logical connection established between a remote microprocessor and mainframe host computer for the express purpose of uploading, downloading, or viewing interactive data and databases on-line in real time. Note: A micro-mainframe link usually requires terminal emulation software on the microcomputer.
Industry:Telecommunications
A physical or logical network that provides data communications to a larger number of independent users than are usually served by a local area network (LAN) and is usually spread over a larger geographic area than that of a LAN. Note 1: WANs may include physical networks, such as Integrated Services Digital Networks (ISDNs,) X. 25 networks, and T1 networks. Note 2: A metropolitan area network (MAN) is a WAN that serves all the users in a metropolitan area. WANs may be nationwide or worldwide.
Industry:Telecommunications
A physical plant, or a designated and specially configured part thereof, that (a) contains the equipment necessary for ensuring fast, reliable, and secure exchange of information, (b) typically includes distribution frames and associated panels, jacks, and switches and monitoring, test, conditioning, and orderwire equipment, and (c) allows telecommunications systems control personnel to exercise operational control of communications paths and facilities, make quality analyses of communications and communications channels, monitor operations and maintenance functions, recognize and correct deteriorating conditions, restore disrupted communications, provide requested on-call circuits, and take or direct such actions as may be required and practical to provide effective telecommunications services.
Industry:Telecommunications
A physical point at which a circuit may be accessed. 2. In an Open Systems Interconnection (OSI) layer, a point at which a designated service may be obtained.
Industry:Telecommunications
A pictorial representation of a pushbutton on a display screen, which functions as a binary control, for example, on/off.
Industry:Telecommunications
A pixel of equal width and height; i.e., having an aspect ratio of 1:1 Note: Pixels created by computer graphics usually have an aspect ratio of 1:1. Television technology was not always concerned with pixel aspect ratio. However, modern dependence upon digital electronic post-production (e. G. , image distortion, rotation, or size changes) has underscored the advantages of square pixels, which facilitate simplified programs and pose less risk of artifacts than do pixels that are not square.
Industry:Telecommunications
A plan created by the International Telegraph and Telephone Consultative Committee (CCITT--now, the ITU-T) that provides each telephone subscriber with a unique number. Each world telephone number consists of a country code followed by the national number. By international agreement, the number of digits in the country code plus national number is limited to a total of 15 digits.
Industry:Telecommunications
A plan for backup procedures, emergency response, and post-disaster recovery. Synonym disaster recovery plan. 2. A plan maintained for emergency response, backup operations, and post-disaster recovery for an information system (IS,) to ensure the availability of critical resources and to facilitate the continuity of operations in an emergency situation.
Industry:Telecommunications
A plan for the allocation of unique 10-digit address numbers. The numbers consists of a 3-digit area (numbering plan area) code, a 3-digit office code, and a 4-digit line number. The plan also extends to format variations (e.g., 3-digit and 7-digit address,) prefixes (e.g., 1, 0, 01, and 011,) and special code applications (e.g., service access codes. )
