John,

With regard to the problem you reported, being unable to
communicate with 1822-connected ARPANET hosts (including
gateways): It turns out that the PSN's "community-of-interest"
word for your host was set incorrectly, which had exactly the
effect you reported: the PSN allowed you to communicate with
other X.25-connected hosts, but prohibited you from communicating
with 1822-connected hosts.  Our troubleshooter reports that we've
corrected the problem, and that one of your folks has confirmed
that you can now communicate normally with 1822-connected hosts.

The "community-of-interest" word is a per-host configuration item
in the PSN; unfortunately we can't tell how it came to be set
wrong.  Most likely it occurred in the (all-too-manual) process
of setting up the PSN 7 configuration items based on the existing
PSN 6 configuration.  Our apologies.

Ken Pogran
