Verifying Network Addresses, the Network,
and DBM Operation
Establish a backup connection and perform a Digital
Test over the backup connection to ensure that the
switched network is functioning. Access the DSU’s
identity (ID) subbranch for the tributary DSU to ensure
that the DSU is properly addressed.
Verify that no alarms appear in the Device Health and
Status subbranches. Refer to the Verifying Operation and
Testing Connections section of Chapter 2 for procedures
that lead you through each of these procedures.

Refer to the Test Branch section of Chapter 4 for further
