Space data and information transfer systems — Space link extension (SLE) — Return operational control fields service

Apstrakt

ISO 26143:2007 defines the space link extension (SLE) return operational control fields (ROCF) service in conformance with ISO 15396:1998. The ROCF service is an SLE transfer service that delivers to a mission user all operational control fields from one master channel or one virtual channel.
ISO 26143:2007 defines, in an abstract manner, the ROCF service in terms of
the operations necessary to provide the service;the parameter data associated with each operation;the behaviors that result from the invocation of each operation; andthe relationship between, and the valid sequence of, the operations and resulting behaviors.
ISO 26143:2007 does not specify
individual implementations or products;the implementation of entities or interfaces within real systems;the methods or technologies required to acquire telemetry frames from signals received from a spacecraft;the methods or technologies required to provide a suitable environment for communications; orthe management activities required to schedule, configure, and control the ROCF service.
