Basic Knowledge of Fault Management
z Event
The notices that generated when the system is running normally and should be prompt to users.
z Fault
The departure from system normal running, which may cause low performance .
z Alarm
The notices generated when the system detected faults. According to the auto-detect ability, alarms are group as two types:ADAC Alarm and ADMC Alarm.

Basic Knowledge of Fault Managementz Alarm log: The fault system collects all the alarms and
saves each alarm as one log record;
z Event log: The fault system collects all the events and
saves each event as one log record;
z Alarm list: The alarms need to be focused and dealt;
alarms in the list are counted by alarm types and alarm
source; users monitor the whole network mainly by Alarm
list;
z Alarm merge: Alarms of the same type and generated on
the same NE are shown as one record in the Alarm list.

Basic Knowledge of Fault Management
z Alarm Management
Alarm management involves alarm display and statistics, audio
and visual alarm notification, alarm acknowledgement and
synchronization..
z Alarm Severities
The alarms can be define to critical, major, minor and warning
severities according to the severity of the alarm. You can adopt
corresponding processing strategy for different alarm severities
and redefine the alarm severities.

z Alarm Status
Alarm status refer to the alarm acknowledgement and
clearance status. You can adopt corresponding processing
measures for alarms of different status.

Alarm Correlationz Aim
To reduce the redundant alarms.
z Correlative alarms
Correlative alarms are alarms that have correlations between
one another. One is the root alarm that raises other alarms.
A fault may result in multiple alarms, the non-root alarms do
not help in the fault location or analysis.
Page32Copyright 2010 Huawei Technologies Co., Ltd. All rights reserved.
Alarm Correlationz Intermittent Alarms
If the interval between two clearance times of an alarm is less than set period of the cleared alarm, the alarm is an intermittent alarm.
z Repeat Events If the reporting times of an event is more than the set times in the set
period, the event is a repeat event.
z Simple/Advanced Correlation the correlation of the intermittent alarms or repeat events is
considered as simple correlation alarms.
the correlation of the other alarms is considered as advanced correlation alarms.

Principles of Correlationz Two conditions
Alarm interval T Unit: second
If the alarm interval is less than or equivalent to T, the first alarm will enter the fault alarm current table or event alarm table. And the subsequent alarms whose alarm intervals are less than or equivalent to T will be saved to mask table or abandoned directly according to the correlation rules.
High frequency alarm threshold N Unit: times
If the system receives certain alarms (alarm intervals T and number of alarms N ) of the NE continuously, the system will generate high frequency alarms whose Equipment Serial Number is 0 and alarm level is higher. For fault alarms, if the subsequent alarm interval of the alarms are more than T, the high frequency alarm will clear.
Page35Copyright 2010 Huawei Technologies Co., Ltd. All rights reserved.
Principles of Correlationz Examples
The correlation configuration of the MSCe is as follows: The fault alarm whose alarm level is Major is E1/T1 Loss of Signal
(ID=1101)
The interval of the alarm is 10s.
The times of high frequency alarm is 10.
The alarms meeting the correlation are saved to the mask table.

Principles of Correlationz Examples
Suppose T1 to T12 10 s, the M2000 will generate a E1/T1 Loss of Signal alarm for MSCe at t1. The alarm level is Critical and the alarm will clear at t2.
The first alarm is saved to fault alarm current table and the 2-12 alarms are saved to alarm mask table.

Defining an User-Defined Alarm
Page43Copyright 2010 Huawei Technologies Co., Ltd. All rights reserved.
Binding a User-Defined Alarmz To define the corresponding relations between the user-
defined alarms and the signal input ports. When a signal
received through a port meets the alarm triggering
conditions, the NE reports an alarm to the M2000, and the
alarm is bound with a customized name and ID.

Summaryz This course mainly discuss about the fault management. In
this course, we need to master some basic concept related
to FM, and master how to perform the FM.
