In data transmission, the condition assumed by a primary or secondary station upon correct receipt of a frame for processing.

The condition that exists when a system or functional unit meets the specified performance and security requirements.

In fiber optics, half the vertex angle of that cone within which optical power may be coupled into bound modes of an optical fiber.
Note 1: The axis of the cone is collinear with the fiber axis, the vertex of the cone is on the fiber end-face, and the base of the cone faces the optical power source.
Note 2:… (Read More →)

In fiber optics, the cone within which optical power may be coupled into the bound modes of an optical fiber.
Note: The acceptance cone is derived by rotating the acceptance angle about the fiber axis. [After 2196]

See acceptance test.

The bound on performance that is allowed at service turnup or interexchange carrier (IC) acceptance of a circuit or connection, or when corrective action is taken to restore a parameter after an immediate action limit (IAL) failure. Performance as measured by a parameter is satisfactory if the value of the parameter is equal to or better than the limit. [T1.208-1989]

1. Of an antenna, for a given plane, a distribution plot of the off-axis power relative to the on-axis power as a function of angle or position. [After 2196]
Note: The acceptance pattern is the equivalent of a horizontal or vertical antenna pattern.
2. Of an optical fiber or fiber bundle, a curve of total transmitted power plotted against the… (Read More →)

A test of a system or functional unit to ensure that contractual requirements are met.
Note: An acceptance test may be performed at the factory or user premises by the user, vendor, or a third party.

Operating and testing of a communication system, subsystem, or component, to ensure that the specified performance characteristics have been met.

A trial carried out by nominated representatives of the eventual military users of the weapon or equipment to determine if the specified performance and characteristics have been met.
