The following essential elements are the minimum required to develop a JAS-compliant system.

Communication Interface (physical, preferably serial)

Protocols to communicate over the physical interface

Network-connected nodes that implement the communication interface and protocols

Network routing and addressing scheme(s)

All of these items are tailorable based on recommendations in the JAS standard. A fully JAS adopted system would have all of the above plus consider using all of the mutually exclusive recommendations in the JAS standard. For example, VITA 46 vs. VITA 78 would be a mutually exclusive decision that would need to be made for either the backplane or form factor, or both.

Programs are required to select a subset of JAS standard recommendations which will be implemented for their particular application. This subset will allow compliance against program requirements as well as maximize the use of the JAS methodology.
