When the local access network fails, use one of two
troubleshooting levels to isolate the source of the problem:

System-level troubleshooting—includes alarms,
indicators, and messages to help isolate the problem to the
CPX, cables, ports, or other equipment.

Component-level troubleshooting—includes
procedures and tests to isolate the problem to a
configuration or provisioning error, or a failed component.
