In a communications network, a single transmission channel between two points that are switching centers or nodes, or both. 2. A circuit between switchboards or other switching equipment, as distinguished from circuits which extend between central office switching equipment and information origination/termination equipment. Note: Trunks may be used to interconnect switches, such as major, minor, public and private switches, to form networks.
Industry:Telecommunications
In a communications network, a station that (a) is responsible for performing unbalanced link-level operations as instructed by the primary station and (b) interprets received commands and generates responses.
Industry:Telecommunications
In a communications network, one or more communications links that (a) are used to provide local area communications service among several locations and (b) collectively form a node in the network. Note 1: An interconnect facility may include network control and administrative circuits as well as the primary traffic circuits. Note 2: An interconnect facility may use any medium available and may be redundant.
Industry:Telecommunications
In a communications network, operation that allows a call to be established among three or more stations in such a manner that each of the stations is able to communicate directly with all the other stations. Note: In radio systems, the stations may receive simultaneously, but must transmit one at a time. The common operational modes are "push-to-talk" for telephone operation and "push-to-type" for telegraph and data transmission.
Industry:Telecommunications
In a communications network, the portion of a device directly connected to the internal station facilities, such as toward a switchboard or toward a switching center. 2. The central office side of test jacks. 3. A wire or cable from a pole or cable terminus to a building. 4. To delete, intentionally or unintentionally, or to lose part of a signal, such as dropping bits from a bit stream.
Industry:Telecommunications
In a communications network, the predefined address that is used as an address for all users of that network, and that may not be the address of an individual user, or subgroup of users, of the network.
Industry:Telecommunications
In a communications network, the state of data circuit-terminating equipment (DCE) when connected to a communications channel and ready to transmit data, usually digital data. Note: When in the data mode, the DCE is not in a talk or dial mode.
Industry:Telecommunications
In a communications network, the station that selects the master station and supervises operational procedures, such as polling, selecting, and recovery. Note: The control station has the overall responsibility for the orderly operation of the entire network. 2. A fixed station whose transmissions are used to control automatically the emissions or operations of another radio station at a specified location, or to transmit automatically to an alarm center telemetering information relative to the operation of such station.
Industry:Telecommunications
In a communications path, an analysis that (a) includes the overall evaluation of the component quality measures, the individual link quality measures, and the aggregate path quality measures, and (b) is performed by evaluating communications parameters, such as bit error ratio, signal-plus-noise-plus-distortion to noise-plus-distortion ratio, and spectral distortion.
Industry:Telecommunications
In a communications switch, a state or condition that occurs when more subscribers attempt simultaneously to access the switch than it is able to handle, even if unsaturated. 2. In a saturated communications system, the condition that occurs when an additional demand for service occurs.
