The combination of the MTP (message transfer part) and the SCCP (signaling connection control part. )
Industry:Telecommunications
The combination of digits to be dialed by a calling subscriber making a call to a subscriber in another country to obtain access to the automatic outgoing international equipment.
Industry:Telecommunications
The combination of classification, categories and caveats associated with an object. Example: "SECRET CORPORATE UK EYES A" Note: Used only in the context of, and at the granularity of, a system's ability to distinguish between security classes. See also: Label, Lattice, Single Class, Multi-class.
Industry:Telecommunications
The combination of (a) interexchange cable and wire facilities, (b) interexchange circuit equipment and, (c) associated land and buildings.
Industry:Telecommunications
The color bar test signal shown in the associated figure, consists of discrete steps of chroma and luminance levels that produce eight different colors superimposed upon standard synchronizing and blanking signals.
Industry:Telecommunications
The collection of residual information from data storage.
Industry:Telecommunications
The collection of documents that describes the requirements, capabilities, limitations, design, operation, and maintenance of a system, such as a communications, computing, or information processing system.
Industry:Telecommunications
The coding of "1's" and "0's" in a message in which one full cycle of a square wave, i.e., a positive pulse followed by a negative pulse in the same bit period, is transmitted when the message bit is a "1" and nothing is transmitted when the bit is a "0", or vice versa. Note: A dipulse signal can be generated by encoding the data into 50% return-to-zero (RZ) unipolar data and sending the bits through an AND gate with the system clock pulse. This RZ bit stream is then delayed one half-bit period and then added to the undelayed RZ stream. This produces the final dipulse waveform. The dipulse power spectrum is similar to that of the biphase coding power spectrum except dipulse coding produces a pulse-repetition rate equal to the bit rate.
Industry:Telecommunications
The code generated by a regenerator upon loss of input signal or loss of frame. The line AIS signal will maintain operation of the downstream regenerators and therefore prevent generation of unnecessary alarms. At the same time, data and orderwire communication is retained between the regenerators and the downstream line terminating equipment (LTE. )
Industry:Telecommunications
The close-in region of an antenna wherein the angular field distribution is dependent upon distance from the antenna. Synonyms near field, near zone. 2. In optical fiber communications, the region close to a source or aperture. Note: The diffraction pattern in this region typically differs significantly from that observed at infinity and varies with distance from the source.
