1. In telephony, all cables, conduits, ducts, poles, towers, repeaters, repeater huts, and other equipment located between a demarcation point in a switching facility and a demarcation point in another switching facility or customer premises. Note: The demarcation point may be at a distribution frame, cable head, or microwave transmitter. 2. In DOD communications, the portion of intrabase communications equipment between the main distribution frame (MDF) and a user end instrument or the terminal connection for a user instrument.
Industry:Telecommunications
1. In telephone industry usage, a service that involves dedicated circuits, private switching arrangements, predefined transmission paths, or combination thereof, whether virtual or physical, and which provide communications between specific locations. 2. Among subscribers to the public switched telephone network (s,) a one-party switched access line.
Industry:Telecommunications
1. In telegraphy, route selection, signaling, and circuit usage and availability for a call. 2. In universal personal telecommunications, the ability of a user to inform the network how to handle incoming calls in accord with certain parameters, such as the call originator, the time of day, and the nature of the call. Note: Call management is accomplished by means of information in the user's service profile.
Industry:Telecommunications
1. In telecommunications, the functional separation of telecommunications networks. A jurisdiction is one of the following four types: (a) local exchange carrier network; (b) interexchange carrier network; (c) end user network; (d) some combination of the above. 2. Loosely, and in a more general sense, the regulatory authority of the Federal Communications Commission as specified in the Communications Act of 1934, supplements thereto, and numerous court decisions; and the regulatory authority of state regulatory commissions as specified in the laws established by each state.
Industry:Telecommunications
1. In signal propagation, see fading. 2. In video, the act of dissolving a video picture to either a color, pattern, or titles. Note: Fading a video image is often used as an artistic tool in video productions, usually seen as a fade to black. 3. In audio, a decrease in the sound level until it is no longer audible.
Industry:Telecommunications
1. In security, a list of entities, together with their access rights, that are authorized to access a resource. 2. A mechanism implementing discretionary and/or mandatory access control between subjects and objects. 3. A list associated with an object specifying the access rights of subjects to that object. 4. A set of control attributes. It is a list, associated with a security object or group of security objects. The list contains the names of security subjects and the type of access that may be granted. 5. A list of entities, together with their access rights which are authorized to have access to a resource. 6. Discretionary access control mechanism associated with an object, consisting of a list of entries, where each entry is a subject identifier coupled with a set of access permissions.
Industry:Telecommunications
1. In packet- and message-switching communications networks, the collection of hardware and software that makes use of packet or message switching to support user-to-user, i.e., end-to-end, communications, interprocess communications, and distributed data processing. 2. Synonym host computer. 3. A computer system attached to a network.
Industry:Telecommunications
1. In optical measurements or specifications, a pair of usually straight contiguous stripes of equal width and having a defined degree of contrast, and which are used as one means of defining or determining resolution. Note 1: Resolution may be expressed in terms of line pairs per unit distance, or line pairs per unit angle. Note 2: Optical "targets," consisting of many contiguous line pairs, are sometimes used to measure optical resolution. Such targets may have line pairs of high contrast, in which one stripe is "white," or highly reflective, at the wavelength (s) of interest, and the adjacent one, "black," or highly absorbent at the wavelength (s) of interest. Other such targets may have line pairs of lower contrast ("shades of gray". ) Resolution may be specified or measured with respect to either or both kinds of target. 2. In raster-scanned television technology, two adjacent scanning lines (traces. )
