1.3.112.4.30.2 (N)-entity An active element within an (N)-subsystem embodying a set of capabilities defined for the (N)-layer that corresponds to a specific (N)-entity-type (without any extra capabilities being used). [ccsds-910.2-G-1] Provisional
1.3.112.4.30.3 (N)-entity-invocation A specific utilization of part or all of the capabilities of a given (N)-entity (without any extra capabilities being used). [ccsds-910.2-G-1] Provisional
1.3.112.4.30.4 (N)-entity-type A description of a class of (N)-entities in terms of a set of capabilities defined for the (N)-layer. [ccsds-910.2-G-1] Provisional
1.3.112.4.30.5 (N)-function A part of the activity of (N)-entities. [ccsds-910.2-G-1] Provisional
1.3.112.4.30.6 (N)-layer A subdivision of the Open Systems Interconnection (OSI) architecture, constituted by subsystems of the same rank (N). [ccsds-910.2-G-1] - [ccsds-A02.1-Y-3] Provisional
1.3.112.4.30.7 (N)-layer Any specific layer in a multi-layer protocol stack. The layer above is called the (N+1)-layer, the layer below is called the (N-1)-layer. This notation is also used in the model for other concepts that are related to these layers, for example, (N)-protocol, (N+1)-service. [ccsds-311.0-M-1] Provisional
1.3.112.4.30.8 (N)-layer management Functions related to the management of the (N)-layer partly performed in the (N)-layer itself according to the (N)-protocol of the layer (activities such as activation and error control) and partly performed as a subset of systems management. [ccsds-910.2-G-1] Provisional
1.3.112.4.30.9 (N)-layer operation The monitoring and control of a single instance of communication. [ccsds-910.2-G-1] Provisional
1.3.112.4.30.10 (N)-protocol A set of rules and formats (semantic and syntactic) which determines the communication behavior of (N)-entities in the performance of (N)-functions. [ccsds-910.2-G-1] Provisional
1.3.112.4.30.11 (N)-protocol-control-information Information exchanged between (N)-entities, using an (N-1)-connection, to coordinate their joint operation. [ccsds-910.2-G-1] Provisional
1.3.112.4.30.12 (N)-protocol-data-unit A unit of data specified in an (N)-protocol and consisting of (N)-protocol-control-information and possibly (N)-user data. [ccsds-910.2-G-1] Provisional
1.3.112.4.30.13 (N)-service A capability of the (N)-layer and the layers beneath it, which is provided to (N+1)-entities at the boundary between the (N)-layer and the (N+1)-layer. [ccsds-910.2-G-1] Provisional
1.3.112.4.30.14 (N)-service-access-point the point at which (N)-services are provided by an (N)-entity to an (N+2)-entity. [ccsds-910.2-G-1] Provisional
1.3.112.4.30.15 (N)-service-data-unit an amount of information whose identity is preserved when transferred between peer-(N+1)-entities and which is not interpreted by the supporting (N)-entities. [ccsds-910.2-G-1] Provisional
1.3.112.4.30.16 (N)-service-user The user of the service provided by the (N)-service-provider. [ccsds-910.2-G-1] Provisional
1.3.112.4.30.17 (N)-subsystem An element in hierarchical division of an open system which interacts directly only with elements in the next higher division or the next lower division of that open system. [ccsds-910.2-G-1] Provisional
1.3.112.4.30.18 (N)-user-data The data transferred between (N)-entities on behalf on the (N+1) entities for whom the (N)-entities are providing services. [ccsds-910.2-G-1] Provisional
1.3.112.4.30.19 9/7 DWT A DWT using a nine-tap filter to obtain low-pass wavelet coefficients and a seven-tap filter to obtain high-pass wavelet coefficients. Two different specific 9/7 Discrete Wavelet Transforms are recommended: 9/7 Float DWT for lossy compression and 9/7 Integer DWT for lossless compression. [ccsds-120.1-G-1] - [ccsds-122.0-B-1] Provisional
1.3.112.4.30.20 9/7 Float DWT Three-level 9/7 DWT whose filter coefficients are specified real numbers. Implemented using float arithmetic. [ccsds-120.1-G-1] - [ccsds-122.0-B-1] Provisional
1.3.112.4.30.21 9/7 Integer DWT Three-level 9/7 DWT whose filter coefficients are specified rational numbers. Implemented using integer arithmetic. [ccsds-120.1-G-1] - [ccsds-122.0-B-1] Provisional
