A block not delivered to the intended destination.

Values which provide a means to identify the beginning and end of adjacent fields for mechanized systems, and to simplify overall code readability. While the specific values may differ from system to system, acceptable values are either an asterisk (*), virgule (/), or a period (. ).

An item produced or used during development of a system that is required to be made available to the evaluators for evaluation purposes.
Note: Includes support and access to computers [CESG].

A successfully transferred block.

A frame D received by a particular destination user when both of the following conditions are true: D was not generated by the source user; D is exactly the same as a frame that was previously delivered to that destination. [after T1.615-1992]

A delivered frame when the value of one or more bits in the frame is in error, or when some, but not all, bits in the frame are lost bits or extra bits (i.e., bits that were not present in the original signal). [After T1.615-1992]

A delivered frame, Fi, that arrives at the destination user after any of the frames F(i+1), F(i+2), . . . Fn, assuming that F1 is transmitted first, F2, second, etc. [After T1.615-1992]

A bit that (a) is successfully transferred to a destination user, (b) performs its primary function within the telecommunications system, and (c) does not represent user information.

A block that (a) is successfully transferred to a destination user, (b) performs its primary function within the telecommunications system, and (c) does not contain user information bits.

The process whereby a copy of the Target of Evaluation is transferred from the developer to a customer [ITSEC].
