Details Provisional (N)-association A cooperative relationship among (N)-entity-invocations. [ccsds-910.2-G-1] 1.3.112.4.30.1
Details Provisional (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] 1.3.112.4.30.2
Details Provisional (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] 1.3.112.4.30.3
Details Provisional (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] 1.3.112.4.30.4
Details Provisional (N)-function A part of the activity of (N)-entities. [ccsds-910.2-G-1] 1.3.112.4.30.5
Details Provisional (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] 1.3.112.4.30.6
Details Provisional (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] 1.3.112.4.30.7
Details Provisional (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] 1.3.112.4.30.8
Details Provisional (N)-layer operation The monitoring and control of a single instance of communication. [ccsds-910.2-G-1] 1.3.112.4.30.9
Details Provisional (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] 1.3.112.4.30.10
Details Provisional (N)-protocol-control-information Information exchanged between (N)-entities, using an (N-1)-connection, to coordinate their joint operation. [ccsds-910.2-G-1] 1.3.112.4.30.11
Details Provisional (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] 1.3.112.4.30.12
Details Provisional (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] 1.3.112.4.30.13
Details Provisional (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] 1.3.112.4.30.14
Details Provisional (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] 1.3.112.4.30.15
Details Provisional (N)-service-user The user of the service provided by the (N)-service-provider. [ccsds-910.2-G-1] 1.3.112.4.30.16
Details Provisional (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] 1.3.112.4.30.17
Details Provisional (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] 1.3.112.4.30.18
Details Provisional 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] 1.3.112.4.30.19
Details Provisional 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] 1.3.112.4.30.20
Details Provisional 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] 1.3.112.4.30.21
Details Provisional (TM) Transfer Frame Protocol data unit of the TM Space Data Link Protocol. 1.3.112.4.30.22
Details Provisional (TC) Transfer Frame Protocol data unit of the TC Space Data Link Protocol. [ccsds-230.0-G-1] 1.3.112.4.30.23
Details Provisional (AOS) Transfer Frame Protocol data unit of the AOS Space Data Link Protocol. 1.3.112.4.30.24
