I'm 99.44% sure that in Phase III days both PDP-10 operating systems were still non-routing Phase II nodes with only one link to a dedicated front end PDP-11 (via the DTE hardware that could handle upto four). Before Phase III everything had to be manually routed, A::B::C -- I forget the name of the passthru service that facilitated that. My memory is that the software running on the '11 was called MCB. Ah, looks like I've posted similarly in the past on the SimH list: https://groups.io/g/simh/topic/decnet/105849791
