|
|
.Sh DESCRIPTION
|
|
The
|
|
.Nm ddn
|
|
device provides a
|
|
.Tn DDN
|
|
Standard Mode
|
|
.Tn X.25
|
|
interface to an
|
|
.Tn IMP
|
|
using
|
|
the
|
|
.Tn ACC ACP625
|
|
.Tn X.25
|
|
board. It is normally used for connecting to
|
|
the Defense Data Network
|
|
.Pq Tn DDN .
|
|
The controller itself is not accessible
|
|
to users, but instead provides a network interface for the
|
|
Internet Protocol described in
|
|
.Xr ip 4 .

|
|
.Pp
|
|
.It DDN: illegal X25 address length!
|
|
.It DDN: illegal X25 address format!
|
|
These errors indicate a problem with the called

.Tn X.25
|
|
address received
|
|
from the

|
.Tn IMP
|
|
on an incoming call.
