ISO 22669:2013 defines the space link extension (SLE) return-all-frames (RAF) service in conformance with the SLE reference model (ISO 15396:2007). The RAF service is an SLE transfer service that delivers to a mission user all telemetry frames from one space link physical channel.
ISO 22669:2013 defines the RAF 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, and
the relationship between, and the valid sequence of, the operations and resulting behaviors.
It 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, or
the management activities required to schedule, configure, and control the RAF service.
