ISO 18444 pdf download Space data and information transfer systems — Space Link Extension — Application Program Interface for Return Operational Control Fields Service
This lnternational Standard specifies extensions to the API needed for support of the Return OperationaControl Fields (ROCF) service defined in Space Link Extension-Return Operational Control Fields ServiceSpecification,CSDS 911.5-B-1.
This International Standard defines extensions to the SLE API in terms of:
the ROCF-specific functionality provided by API components;
the ROCF-specific interfaces provided by API components; and
the externally visible behavior associated with the ROCF interfaces exported by the components.
lt does not specify:
individual implementations or products;
the internal design of the components; and
the technology used for communications
This lnternational Standard defines only interfaces and behavior that must be provided by implementationssupporting the Return Operational Control Fields service in addition to the specification in Space LinkExtension-Application Program lnterface for Transfer Services-Core Specification, CCSDS 914.0-M-1.
The scope and field of application are furthermore detailed in subclause 1.3 of the enclosed CCSDSpublication.
