Installing the Model 3616 DualFlow DSU
Verifying Operation and Testing Connections
Perform verification testing after any installation.
After installing and configuring the circuit (including control and tributary DSUs, the DDS network, the DBMs and their dial connections), perform a series of tests from the control DSU to verify network operation (using either the SDCP or NMS).
To Connect the SDCP to a DSU
For the
.Procedure
1.Press the Select key (refer to Figure
Carr:Slot: |
| 1: 01 A |

The cursor is usually positioned under the second position of the slot number (1:0 1 ).
In this example, the first line shows
•1 indicates Carrier 1 (Carr)
•01 indicates the DSU in Slot 1
•A is reserved for future use
On the second line
•Press the F1 key ( ↑ ) to increment the number that the cursor is on.
•Press the F2 key ( ↓) to decrement the number.
•Press the 
and 
keys to move the cursor one position to the left or right, to change either the carrier or slot number.
•Press the F3 key to toggle between DSUs, to switch from 1:01A to 1:02A in this example. (In our example, the previously accessed DSU was located in Slot 2 of Carrier 1.)
2.Press the Select key on the SDCP again.
The SDCP accesses the DSU in Carrier 1, Slot 1. The

From the first line of this example, you can see that this is a
9.6 kbps, and is configured as a control (C).
From the second line you can see that there are no NMS messages (no Msg branch over the F3 key) waiting to be read and cleared.
Also note that the SDCP indicator on the selected DSU's faceplate, Front Panel, is lit.
