ISO 22670:2006

ISO 22670:2006 specifies a return-channel-frames (RCF) service for a space link extension (SLE). The RCF service is an SLE transfer service that delivers to a mission user all telemetry frames from one master channel or one virtual channel. It defines, in an abstract manner, the RCF service in terms of the operations necessary to provide the service;the parameter data associated with each operation;the behaviours that result from the invocation of each operation; the relationship between, and the valid sequence of, the operations and resulting behaviours.
