The system-independent application activities that are made available as application services to the application agent, e.g., a set of application service elements that together perform all or part of the communication aspects of an application process.
Industry:Telecommunications
The time during which frame alignment is effectively lost. Note: The out-of-frame-alignment time includes the time to detect loss of frame alignment and the alignment recovery time.
Industry:Telecommunications
The signaling point code, containing for U. S. National networks, the network identification, network cluster, and network cluster member fields (24 bits. )
Industry:Telecommunications
The subtending remote switching device that depends in part on its host switch for call control but is capable of providing intra-unit switching.
Industry:Telecommunications

Industry:Telecommunications
The use of (usually) electronic means, passive or active, to obtain information about the nature, position, or movement of, e.g., aircraft (cooperative or non-cooperative, friendly or unfriendly,) sources of electromagnetic emissions, etc. 2. Nonintrusive monitoring of digital signals in real time to recognize performance degradations and failures and system intrusion attempts.
Industry:Telecommunications
The situation that occurs when many stations transmit simultaneously using frequencies that are close together, i.e., with insufficient width of frequency guard bands or channel spacing. Note: Frequency spectrum congestion causes (a) difficulty in discrimination by tuning, (b) overlap of (i) a sideband and an adjacent carrier, or (ii) upper and lower sidebands, respectively, of adjacent carriers, and (c) interference that occurs when frequencies shift slightly or are phase shifted by ionospheric reflection.
Industry:Telecommunications
The signal level at a receiver input terminal. Note 1: The signal bandwidth and the established reference level must be specified. Note 2: The RSL is usually expressed in dB with respect to 1 mW, i.e., 0 dBm.
