The product you were referring to is by Interlink Computer Sciences.
It uses a channel-attached box for high-speed transfer.
IBM host (VM or MVS) appears to be a DECnet host.
transparent from DECnet viewpoint.
From the sales blurb I have:

                information from a DECnet node
        Permits DEC users to send and retrieve information from any MVS host
                using DCL
        Provides high-speed, high volume, bi-directional information transfe.r
        Attaches directly to an IBM channel and bypasses the IBM FEP (eg 3705);
                it is build using a PDP 11
        Links to DECnet via Ethernet or conventional point-to-point
        Interfaces to RACf, ACF2 & TOPSECRET; MVS/XA & VM supported
