One pertinent piece of information you left out of your message is where
is the PSN (aka IMP) you are connecting to....  If the PSN is local
to you then DH should be more than adequate.  If you are having
problems getting a DH interface for the PSN then you should go back
to your sponsoring organization and raise your collective organizational
voice.  On the other hand, if the PSN is NOT local and you trying
to connect to one miles away (or more than 2K feet away), then you
really do need HDH.  The only other alternative is to put ECU boxes
on each end of the connection (one at the gateway and one at the
PSN).  This will work just fine (we have lots of ECUs here), but
DDN would rather you didn't throw extra boxes on the line that they
can't remotely diagnose.
