A communication path between local exchange and a customer interface (CI. )
Industry:Telecommunications
A communication service involving teletypewriters connected through automatic exchanges.
Industry:Telecommunications
A communication session, facilitated by means of a computer network, between several participants, each of them having access to all messages submitted. Note: Messages, in general, have no specified recipient, but are sent to the entire membership. Messages may contain text, video, audio, graphics, software, or a combination thereof. Some of these may be contained in the message and may be stored on line for future retrieval. Computer conferencing can be conducted either in real time or in store-and-forward mode.
Industry:Telecommunications
A communication system service feature that enables the system to complete an access attempt in spite of issuance of a user blocking signal. Note: Systems that provide this feature monitor the busy user until the user blocking signal ends, and then proceed to complete the requested access. This feature permits holding an incoming call until the called party is free.
Industry:Telecommunications
A communications arrangement in which data from a source user may be passed to a destination user over various real circuit configurations during a single period of communication. Note: Virtual circuits are generally set up on a per-call basis and are disconnected when the call is terminated; however, a permanent virtual circuit can be established as an option to provide a dedicated link between two facilities. Synonyms logical circuit, logical route.
Industry:Telecommunications
A communications cable designed for installation on, or suspension from, a pole or other overhead structure.
Industry:Telecommunications
A communications cable having both optical and metallic signal-carrying components. Note 1: A cable having optical fiber (s) and a metallic component, e.g., a metallic twisted pair, used solely for conduction of electric power to repeaters, does qualify as a composite cable. Note 2: A cable having optical fiber (s,) plus a metallic strength member or armor, does not qualify as a composite cable.
Industry:Telecommunications
A communications channel allocated to the user for input of information such as data communication for use in maintenance activities and removing of alarms external to the span equipment in a proprietary fashion.
Industry:Telecommunications
A communications channel from a switching center or an individual message distribution point to the user terminal. Synonym subscriber line. 2. A pair of wires, or its equivalent, between a customer's station and the central office from which the station is served. Synonyms local loop, user line. 3. Go-and-return conductors of an electric circuit; a closed circuit. 4. A closed path under measurement in a resistance test. 5. A type of antenna, in the form of a circle or rectangle, usually used in direction-finding equipment and in UHF reception. 6. A sequence of instructions that may be executed iteratively while a certain condition prevails until the loop has been executed once.
