Displaying External Leads
The Display (Displ) selection allows you to view the
external lead states. When Display is selected, the
External Leads status report appears showing the current
status of the general-purpose external leads on the
EIA-232-D/V.24 interface.
Changing External Leads
The Change (Chang) selection allows you to change
the state of the two output leads (for example, to change a
lead to signal a console operator or to reset a remote
computer). Leads can be changed from the NMS.
After the leads are set, press the F2 key to save the
leads in the specified state.
Reporting External Lead Changes to NMS
Changing either the output leads or the input leads
changes the DSU’s health and status message.
If the DSU is polled by the NMS, the NMS reports a
change configuration notification (CCN) event. The NMS
operator can then issue a CCN Display command to
determine what caused the event.

If a positive (+) voltage is detected in either one of
the input leads, an external leads alarm is also
reported.
