It is normally used for connecting to 67the Defense Data Network 68.Pq Tn DDN . 69The controller itself is not accessible 70to users, but instead provides a network interface for the 71Internet Protocol described in 72.Xr ip 4 . 73.Sh DIAGNOSTICS 74.Bl -diag 75.It ddn%d: not alive. 76The initialization routine was entered even though the device 77did not autoconfigure. This indicates a system problem. 78.Pp 79.It ddn%d: failed getting UBA resources for lcn %d." 80Insufficient 81.Tn UNIBUS 82resources existed to initialize the device. 83This is likely to be a shortage of 84.Tn UNIBUS 85mapping registers. 86.Pp 87.It ddn%d: couldn't get X25 init buffer. 88This indicates that an 89.Em mbuf 90could not be allocated for sending the initialization message to the 91.Tn ACP Ns 625 . 92.Pp 93.It DDN: illegal X25 address length! 94.It DDN: illegal X25 address format! 95These errors indicate a problem with the called 96.Tn X.25 97address received 98from the 99.Tn IMP 100on an incoming call. 101.Pp 102.It X25 RESET on lcn = %d. 103This indicates that an unexpected 104.Tn X.25 105.Tn RESET 106was received on the 107indicated 108.Tn LCN . 109.Pp 110.It X25 INTERRUPT on lcn = %d, code = %d. 111This indicates that an unexpected 112.Tn X.25 113.Tn INTERRUPT 114Packet was received on the 115indicated 116.Tn LCN . 117.Pp 118.It ddn%d: failed to get supr msg bfr! 119This indicates that an 120.Em mbuf 121could not be allocated for sending a supervisor message to the 122.Tn ACP625 . 123.El 124.Pp 125Any other error message from 126.Ql ddn%d: 127indicates a serious error 128detected by either the driver or the 129.Tn ACP Ns 625 130firmware. 131.Sh SEE ALSO 132.Xr ip 4 , 133.Xr netintro 4 134.Sh HISTORY 135The 136.Nm 137interface appeared in 138.Bx 4.3 . 139
