DSU Operations

Results
The DSU displays the following when the local DSU
transmitter is enabled:
F1
DSU: Enable
Command Complete
F2 F3
When the DSU transmitter is disabled, the following is
possible:
•
Disabled tributaries and the control respond to tests;
aborting a test clears the test but the unit remains
disabled.
•
A tributary or control in test clears the test when a
Disable (or Enable) command is received.
•
If an Enable command is executed to a control from
the NMS or local DCP, all disabled tributaries are
enabled; all tributaries in test are restored to Data
mode.
LEDs
The LEDs selection is only available from the Local
branch. This selection allows you to monitor the port at
any given time. When selected, the port’s lead activity is
reflected in the DCP circuit designation status indicators
(TXD, RXD, etc.) on the faceplate of the Model 3611
DSU, or on the DCP of the Model 3610 DSU.
External Leads
The External Leads (ExtL) selection allows you to
display the state of four general-purpose leads on the
EIA-232-D/V.24 Port 1 interface: Pins 12 and 13 for
output (control leads) and Pins 19 and 23 for input (alarm
leads). If the configuration option External Leads (Ext
Leads) is set to ExtLd, you can change the state of the two
output leads from the DCP or a 6700 or 6800 Series NMS.
If the DSU’s diagnostic protocol is ADp and the CCN by
External Leads (CCN by EL) configuration option has
been enabled, a control DSU reports any changes to the
four leads to the 6700 or 6800 Series NMS as part of its
health and status poll response.
If you have a modular DSU, you can use Paradyne’s
NMS adapter cable (3000-F2-510) to access Pins 12, 13,
19, and 23 to make use of external leads.
To access the External Leads selection from the
top-level menu, make the following selections:
•
Local (F1), or Remot (F2) and Address
