1. A control character used by some conventions to indicate that the data with which it is associated are in error or are to be disregarded.
2. An accuracy control character used to indicate that the data with which it is associated are in error, are to be disregarded, or cannot be represented on a particular device.

CANT is a trunk group control that allows traffic to be canceled before hunting for a circuit to a destination. Equipment vendors commonly provide the capability to implement this control on a percentage basis.

The luminous intensity in a specified direction, of a monochromatic source which has a frequency of 540 x 1012 Hz and which has a radiant intensity, in the specified direction, of (1/683) watt per steradian.

A domain name of an Internet resource indicating its type or its capabilities.
Note: One Internet resource may have a set of different domain names, one of which is the preferred one. Example: www. isi. edu denotes a host containing a Web server. [2382-pt.35]

2. As used in the context of security, a form of privilege attribute. It is a token (recognized by a process managing access to security objects) possession… (Read More →)

Synonym alias point code.

The transfer of energy from one circuit to another by means of the mutual capacitance between the circuits.
Note 1: The coupling may be deliberate or inadvertent.
Note 2: Capacitive coupling favors transfer of the higher frequency components of a signal, whereas inductive coupling favors lower frequency components, and conductive coupling favors neither higher nor lower frequency components.

See channel capacity, traffic capacity.
