operating as a DSU (i.e., not as a DBM), at
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.
Verifying Network Addresses, the Network,
and DBM Operation
Access the DSU's identity (ID) subbranch for each
tributary DSU to ensure that the DSUs are properly
addressed.
Perform a Digital Test on the DDS circuit to ensure
that the network is functioning.
If a DBM is installed, perform the Digital Test by
selecting DBM from the Run Test from screen instead of
DSU. Next, test the tributary DBM for dial tone, and
verify that the DSU can place and receive calls.
Refer to the Verifying Operation and Testing
Connections section of Chapter 2 for procedures that lead
you through each of these procedures.
