Abstract / scope
ISO 22669:2003 specifies a return-all-frames (RAF) service for a space link extension (SLE) service. The RAF service is an SLE transfer service that delivers all telemetry frames to a mission user from one space link physical channel.
ISO 22669:2003 defines, in an abstract manner, 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.
