ISO 22669:2007

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.
