This CCSDS Informational Report presents a set of concepts and 
tutorial on a telemetry and telecommand database format for 
spacecraft monitoring and control.

- CCSDS 732.0-B-2, AOS Space Data Link Protocol (Blue Book, Issue 2, July 2006)

The CCSDS Recommended Standard for AOS Space Data Link Protocol 
specifies the protocol, services, and procedures pertaining to the 
CCSDS Version-2 Transfer Frame.   The current issue defines two new 
subfields within the Transfer Frame Primary Header Signaling Field: a 
Virtual Channel (VC) Frame Count Cycle Use Flag and a VC Frame Count 
Cycle subfield, effectively extending the VC Frame Count from 24 to 28 bits.
