z Fault Alarm

It has the occurrence time and clearance time

z Event Alarm

It has the occurrence time but no clearance time


z Critical

The device or resource may be no longer available. The fault must be

removed immediately.

z Major

The Quality of Service (QoS) of the device or resource decreases

greatly. Proper measures must be taken to recover the service.

z Minor

The QoS of the device or resource decreases slightly. Proper

measures must be taken or further observation need to be done to

avoid more severe faults.

z Warning

The QoS of the device or resource may be affected. Proper measures

must be taken.

z All the alarms of the NEs are reported actively to the M2000.

z The alarms of most NEs are reported through port 6001.


z There are four tables in the alarm database (fmdb) to store

the alarms:

Table of current faulty alarms: tbl_cur_alm

Table of History faulty alarms: tbl_his_alm

Event alarm table: tbl_event

Mask alarm table: tbl_mask_alm

z If the alarm service is running, it checks whether the alarm

tables reaches their upper limit every 83 seconds (default

value).

Table tbl_cur_alm can hold a maximum of 100,000 alarms.

Table tbl_his_alm can hold a maximum of 2,000,000 alarms.

Table tbl_event can hold a maximum of 2,000,000 alarms.

Table tbl_mask_alm can hold a maximum of 200,000 alarms.

When surpass the upper limit

Table tbl_cur_alm displaces 10,000 alarms forcibly to history table.

It displaces the earliest cleared and unacknowledged alarms in

priority according to the occurrence time of the alarms . If the

alarms are less than 10,000, it then displaces the earliest un-

cleared and unacknowledged alarms.

Table tbl_his_alm displaces the earliest 20% of the alarms to files

according to the occurrence time of the alarms and deletes them

from the table.

Table tbl_event displaces the earliest 20% of the alarms to files

according to the occurrence time of the alarms and deletes them

from the table.

Table tbl_mask_alm does not displace the alarms to the files. It

deletes the earliest 100,000 alarms from the table directly.

z Modify the alarm information and show some necessary

columns as required.


z Includes Auto and Manual alarm synchronization

Auto alarm synchronization

All the alarms are auto synchronized when the NE is reconnected.

All the alarms are auto synchronized when the UMTS NE is

created, All the active alarms are auto synchronized when the G/C

NE is created.

Manual alarm synchronization

Only the active alarms, which are uncleared fault alarms, will be

synchronized.

z 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.


z 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 repeat events is considered as simple correlation

alarms.

the correlation of the intermittent alarms is considered as simple

correlation alarms.

z Understand the alarm interval T

Fault alarm

Event alarmT0 tT T

T

0 tT T T


z 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.

z 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.

z 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.

Alarm Setting of NE

z The following three functions is delivered to the NE

Alarm shielding

If the alarms are shielded at the NE, they will not be reported to

the LMT and M2000.

Support NEs with NBMML interfaces only.

Alarm level redefinition

Support NEs with NBMML interfaces only.

User defined alarm

Includes alarm definition and alarm binding.

27/34


z Definition

User can define an NE alarm, bind it to a port of a cabinet, subrack, or slot of

the NE, and then connect an external device for environment monitoring. In

this way, when the device detects exceptions, the NE raises an alarm in real

time and reports the alarm to the M2000.

z Alarm definition

The attributes are stored in the M2000 database, user can query, add, modify

the attributes.

z Alarm binding

the binding relation is stored in NE. User can query, add, modify,

cancel the binding in M2000 client.


23

7/30/2019 82859219-M2000Book

28/34


z 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.
