Reporting External Lead Changes to NMS

Changing the output leads from the DCP or NMS, or
changing the input leads, changes the DSU's health and
status message. If the DSU is polled by the NMS using
ADp, the 6800 Series NMS reports a change
configuration notification (CCN) event. The 6700 Series
NMS will also report a change configuration notice if
enabled. The NMS operator can then issue a CCN
Display command to determine what caused the event. If
the event was caused by the state in the external leads, the
operator can select Displ from the External Leads (ExtL)
branch to see the current states of the external leads. In
addition, if a positive voltage is detected in either one of
the input leads, an external leads alarm is also reported.
