A packet layer reference event that corresponds to a packet exiting a network section (to a circuit section) or a packet exiting a DTE (to an access circuit section. )
Industry:Telecommunications
A packet switching technique that increases the throughput by eliminating overhead. Note 1: Overhead reduction is accomplished by allocating flow control and error correction functions to either the user applications or the network nodes that interface with the user. Note 2: Cell relay and frame relay are two implementations of fast packet switching.
Industry:Telecommunications
A packet-switching network used by the Department of Defense, later evolved into the Internet.
Industry:Telecommunications
A pad composed of two discrete components, one series component and one shunt component. Note: In schematic representation, the components resemble the upper-case letter "L," hence the name.
Industry:Telecommunications
A pair of individually insulated conductors (wires) twisted together and treated as an entity in the transmission of electrical signals or power (e.g., from an electronic power supply to a circuit. ) Note 1: In communications cables, the twisted pair is usually if not always composed of two individually insulated solid conductors (wires. ) In other applications, e.g., in a power-supply application, each of the insulated conductors may consist of stranded wire. Note 2: Because the wires are twisted together, interfering signals tend to create opposing electromagnetic forces at frequent intervals, reducing the effect of the interference on the signal or power supply voltage being conducted. Note 3: Twisted pairs may be used for bit rates up to 1 Mb/s over short distances (<100 m) and lower bit rates over longer distances. More sophisticated driver and receiver circuits facilitate similar or higher data rates over longer distances. Note 4: Unshielded twisted pairs (UTPs) are used extensively in telephone networks and in many data communications applications.
Industry:Telecommunications
A pair of parallel buses arranged such that the direction of data flow in one bus is opposite to the direction of data flow in the other bus.
Industry:Telecommunications
A parallel connection used to extract some of the signal energy from a circuit, usually with negligible effect on the normal operation of the circuit.
Industry:Telecommunications
A parameter value consistent with minimum service objectives that are necessary to support high-speed modems. When any parameter values exceeds the SAL, voiceband data performance may be adversely affected, depending on the performance of the remainder of the connection.
Industry:Telecommunications
A parity check performed on a group of binary digits recorded on parallel tracks of a data medium, such as a magnetic disk, tape, drum, or card.
Industry:Telecommunications
A part of a computer that performs arithmetic, logic, and related operations.
