There are hosts on the ARPANET that have successfully interchanged TCP/IP data between X.25 sources and 1822 destinations. The hosts that I am aware of use ACC interfaces. Initial attempts to communicate failed because the hosts were not enabled to cross host access control boundaries established in the subnet. This was corrected earlier this week and tests following the change were considered sucessful. Alan

There is another implementation that I am aware of that is doing Standard Services X.25 to an ARPAnet IMP (oops, PSN). It too talks successfully with other 1822 systems, and does NOT use an ACC board. Sun has announced DDN support (including X.25 Standard and Basic) as a product, so "contact your local Sun sales rep for more information."

Yes, one of them is the operational gateway between the NSFnet and the
Arpanet, because of which I had asked the question in the first place.
Packets between the NSfnet and the Arpanet are now flowing in a more
operational sense than before, even though there are some (non-IMP
related) problems left, i.e., the IMP at PSC/CMU gets only the outgoing
packets at this point of time, while the incoming packets are still
traversing the slower DCNet/UMICH/USAN path. This will be fixed shortly,
but as said, it's not IMP or X.25 interface related. The Standard-X.25
interface appears to be behaving fine, as it's getting packets almost all
week already.
