                      9: .SH DESCRIPTION
                     10: The 
                     11: .I ddn
                     12: device provides a DDN Standard Mode X.25 interface to an IMP using
                     13: the ACC ACP625 X.25 board.  It is normally used for connecting to
                     14: the Defense Data Network (DDN).  The controller itself is not accessible
                     15: to users, but instead provides a network interface for the
                     16: Internet Protocol described in
                     17: .IR ip (4P).

                     22: The initialization routine was entered even though the device
                     23: did not autoconfigure.  This indicates a system problem.

                     26: Insufficient UNIBUS resources existed to initialize the device.
                     27: This is likely to be a shortage of UNIBUS mapping registers.

                     32: could not be allocated for sending the initialization message to the

                     38: .br
                     39: These errors indicate a problem with the called X.25 address received
                     40: from the IMP on an incoming call.
