That rings a bell.  I distinctly remember DECnet/RT being described as "end node only".  That's a Phase III term, it doesn't mean anything for a Phase II node.

As a Phase III node it would be DDCMP only.  I don't remember if it supports any synchronous interfaces, and whether DMC-11 support was included.  If it had DDCMP in software (which you'd need for async ports) then allowing that to talk to sync interfaces like the DUP-11 would not be a  big stretch.
