ISO 22669:2007 PDF

ISO 22669:2007 defines the space link extension (SLE) return-all-frames (RAF) service in conformance with ISO 15396:1998. The RAF service is an SLE transfer service that delivers to a mission user all telemetry frames from one space link physical channel. ISO 22669:2007 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. 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.
