I don't think so. From what I remember, and it’s a long time ago, our DPS/6 front end ran completely different software. The DN355 ran GERTS or GRTS and the DPS/6 ran DNS... https://books.google.co.uk/books?id=w3IudMVoEusC&pg=PA1&hl=en#v=onepage&q&f=false > -- > Michael Thompson I do remember we had some LSI/11 based RNP(707 perhaps) "look alikes" which would drop their connection. When this happened you go the dreaded "unable to contact GRTS" message.... ... some wag added a line to our "message of the day file" which read "who are the GRTS and why are we trying to contact them"...
