Hosts requiring X.25 Standard service must be connected to an IMP running PSN6. I am not certain, but I don't believe many (if any at all) Arpanet IMPs have been converted to run PSN6. Many will require a hardware upgrade (C/30 to C/30E). Maybe someone from BBN can comment on this and give a schedule for upgrading the Arpanet IMPs. Ron Stoughton rms@acc-sb-unix.arpa

All, ARPANET nodes have been upgraded hardware-wise to C/30e's. The upgrade to PSN 6.0 software is proceeding now. However, all nodes have been running PSN 5.0 for several months, and x.25 standard service was even possible before that, under PSN 3.0/4.0 (although it required the loading of a separate x.25 package). -Josh Seeger (BBN Communications, Network Analysis)

The hardware upgrade on the ARPANET is complete. PSN 6 has been deployed to a few nodes, and deployment to other nodes in ongoing. I am not certain if a definite schedule has been established for the remaining nodes, but I would expect that all ARPANET nodes would be running PSN 6 within one month.
