While no specific node-to-node interconnection method is specified in JAS it is highly recommended that the nodes make use of a standards-based chassis and backplane. SpaceVPX is similar to VPX but intended for space applications.
[Placeholder: There may be sub-specs we can reference here, similar to the subspecs for VITA 46 VPX. Content will be developed for JT 2.0.]
