1.1 Functions of Fault Management

The fault management system collects fault information from all the NEs in the managed

network in near real-time, such as boards, links, databases, and servers, and then

displays the collected fault information in the format of alarm or notification. The fault

management system helps the system administrator quickly locate and resolve faults

in the managed network.

departments, and equipment vendors with correct and timely alarm data to ensure stable

network operations.

1.2 Fault Indication

The fault management system indicates a fault or event occurring in the network in the

form of alarm or notification.

1.2.1 Alarm

A fault is indicated in the form of alarm when it persists and affects the reliability and

services of the system. An alarm will be cleared only after the fault is resolved. Immediate

troubleshooting is required when alarms occur.

1.2.2 Notification

A notification indicates a non-repeatable or instantaneous fault or event in the system, for

example, board reset and signaling overload. Such a fault or event is normally caused by

a sudden environment change or other accidental factors. No special handling is required

because the fault or event causing a notification can be automatically handled by the

system. However, a frequently-reported notification requires troubleshooting.
