1. A Signaling System No.7 (SS7) address that is shared by more than one system supporting the same GTT (global title translation) function (or other SS7 function). It allows other systems to address the function instead of maintaining the status of multiple point codes. [T1.711-1999]
2. A point code that may be assigned to more than one signaling point, each… (Read More →)

In any technology or process involving (a) sampling a signal, e.g., an electrical signal or (a series of images of) a moving subject; (b) processing, storing, or transmitting representations of the samples; and (c) replicating the original signal from the representations: the production of artifacts as a result of sampling at intervals too great to permit faithful replication of the… (Read More →)

A bundle of optical fibers in which the relative spatial coordinates of each fiber are the same at the two ends of the bundle.
Note: Such a bundle may be used for the transmission of images. Synonym coherent bundle.

A procedure by which the error rate of a signaling link is measured during the initial alignment process. [After T1.11
0. 2-1992] [After T1.226-1992]

The short-term variations between the optimum sampling instants of a digital signal and the sampling clock derived from it. [T
1. Rpt17-1993]

An equipment condition in which all trunks (paths) in a given trunk group are busy.
Note: All-trunks-busy registers do not indicate subsequent attempts to reach trunk groups.

Synonym all-silica fiber.

An optical fiber composed of a silica-based core and cladding.
Note: The presence of a protective polymer overcoat does not disqualify a fiber as an all-silica fiber, nor does the presence of a tight buffer. [FAA] Synonym all-glass fiber.

One half of the time average over the sum of the squares of the differences between successive readings of the frequency deviation sampled over the sampling period.
Note: The Allan variance is conventionally expressed by y2(). The samples are taken with no dead-time between them. Synonym two-sample variance.

In adaptive high-frequency (HF) radio automatic link establishment (ALE), a general broadcast that does not request responses and does not designate any specific addresses.
Note: This essential function is required for emergencies ("HELP"), sounding-type data exchanges, and propagation and connectivity tracking. [After FED-STD-1045A]
