Step 3: Isolate the Fault
Further isolate and characterize the problem using all available link indications.
Ascertain if the problem is related to:
• End-equipment configuration or an interconnection
• A hardware fault in the link’s accessories (such as a cable)
• Configuration settings (this can be verified using the CLI)
• A hardware fault in one of the ODUs
• A result of larger network propagation problem
Note that Loopback indications are especially useful when isolating the fault’s
component and network location.
Step 4: Correct the Fault
Once the fault is isolated, implement the necessary corrective actions until resolution of
the problem is confirmed.
Whenever possible, it is recommended that you repeat commissioning tests in order to
verify that the problem link is now operating correctly.
