Alarm Types
The alarms in the BSC6800 system can be divided into fault alarms and event alarms:
Fault alarms triggered by hardware fault or abnormity of major functions
Fault alarms can be divided into active or recovery alarms
Event alarms indicate some occasional events generated during the running of the equipments
Event alarms represent an instantaneous state of the system that may not be a fault
Event alarms cannot be divided into active or recovery alarms
Fault alarms have higher severity than event alarms
According to the state of the faults, fault alarms can also be divided into active or recovery alarms:
If the fault is cleared, the state of the alarm will be “Recovery”, and it is called a recovery alarm.
If the alarm is not cleared, the state of the alarm will remain to be "Active”, and it is called an active alarm.
Internal Use
Alarm Severity
The BSC6800 has 4 alarm severity levels (listed in a descending order):
Critical alarm
Reporting faults that affect the services, and need treatment immediately
Major alarm
Reporting faults that affect the QoS, and need treatment in time
Minor alarm
Reporting faults that are not serious enough to affect the QoS, but need treatment at proper time
Warning alarm
Reporting faults that potentially threaten the system services, and need treatment according to specific situations
Internal Use
Event Types
also be divided into 10 types:
Event Types
Correlative Alarms
Power system
Environment system
Alarms related to the equipment room environment, such as temperature, humidity, and access control
Signaling system
Trunk system
Alarms related to the trunk system, including trunk circuits and trunk boards
Hardware system
Alarms related to a board, such as clock and CPU
Software system
Communication system
Alarm related to the communication system, such as the one between hosts and BAM servers

Browsing Alarms
From the alarm browse window in LMT, operator can monitor the alarm information in real time
In LMT, choose Alarm > Browse Alarm or click to display the Alarm Browse window
Internal Use
Browsing Alarms
Double clicking alarm to browse the details of an alarm
Click MORE to browse alarm treatment suggestions.

Managing Alarm Log
Alarm log is used to record details of alarms and can help operator to learn the history operating situation of the system
Querying alarm log:
MML modeLST ALMLOG
GUI modeIn LMT, choose Alarm > Query Alarm Log or click
Internal Use
Managing Alarm Log
Setting alarm log
Alarm log is collected by and saved in BAM. Thus, operator need to set the capacity and time limit of alarm logs in the BAM database in case the logs may occupy too much storage of the hard disk
Setting log capacity and time limit SET ALMCAPACITY
Querying log capacity and time limit LST ALMCAPACITY
Internal Use
Recovering Alarms
When the fault is cleared or can be neglected, operator can manually set the alarm to be recovery
Either MML or GUI mode can be used to recover alarm:
MML mode
RMV ALMFLT
GUI mode
In the fault alarm browse window, press Ctrl + Delete, or right click the alarm and choose Manually Clear Alarm
Internal Use
Filtering Alarms
The alarm filter is used to filter specified alarms, for example, alarms of a WFMRb DSP, or an E1/T1 port
The filtered alarms will not be sent to LMT or M2000

Operator can set alarm filters of different filtering requirements on LMT. Only when the alarm filter is created and activated, it will filter the alarms meeting the requirements. If it is suspended, it will not filter any alarm.
Internal Use
Masking Alarms
The BSC6800 can mask derived alarms and has 4 mask levels: NOMASK, LOW, MEDIUM and HIGH
HIGH: mask most of the derived alarms
MEDIUM: mask alarms not as many as HIGH, but more than LOW
LOW: mask only high-correlation derived alarms
NOMASK: the mask function is not in use

Internal Use
Saving Alarms
Operator can save part or all alarm information in the Alarm Browse window or Query Alarm Log window
To save all alarms: right click and choose Save All Alarms
.
Setting Real time Print of Alarms:
After the setting, only the alarms that meet the requirements can be printed
In LMT, choose Alarm > Alarm Realtime Print Set
Internal Use
Printing Alarms
Setting Manual Print of Alarms:
To print all alarms: right click and choose Print All Alarms
To print part of the alarms: choosing the alarms by <Ctrl> or <Shift> keystroke, right click and choose Print Selected Alarms

Alarm Box Function
Fault alarms sent from BAM to LMT enable the alarm box to give audible and visual indications
Alarm indicators of different colors represent different alarm severity levels:
Red indicator: critical alarm
Orange indicator: major alarm
Yellow indicator: minor alarm
Connecting Alarm Box
1. Connect LMT with alarm box by a serial port cable
2. Choose Start > All Programs > HUAWEI Local Maintenance Terminal > Convert Management System
3. Choose Operate > Configuration
4. Enter the external virtual IP address of the BAM, and choose the COM port for the connection of LMT with alarm box
5. Click OK
In LMT, choose Alarm > Fault Alarm Sound
This task is to specify the severity levels for which the alarm box sounds, as well as how long the alarm box sounds.

Querying Alarm Indicator StatusWhen LMT receives one or more fault alarms of some severity level from BAM, the corresponding indicator on the alarm box will flash. However, you cannot learn how many alarms are happening just from the flashing indicator. This task is to query the number of alarms that the flashing indicators indicate.
Setting Report to Alarm Box FlagThis task is to set if an alarm will be reported to alarm box.
Setting Mask Level of Alarm BoxThis task is to set the mask level of alarm box. After the setting, the LMT will not send any fault alarm below the level to the alarm box.

Fault Testing Function
The function of system fault testing is to collect correlative fault information for locating and clearing alarms
The BSC6800 provides the following fault tests:
Load Control Test
SAAL Test
Other Tests
1. Load Control Test: Testing load control of WMPU, Testing load control of other boards in WRSS, Testing load control of WMUXb, Testing load control of other boards in WRBS, Testing load control of NodeB
2. E1 Test: Testing local E1 loopback, Testing remote E1 loopback, Testing E1 BER
3. AAL2 PATH Test: Testing Iub AAL2 PATH, Testing Iu-CS AAL2 PATH
4. SAAL Test: Testing Iub SAAL link, Testing Iu SAAL link
5. Other Tests: Testing NodeB maintenance IPoA link, Testing Iu-PS IPoA link, Testing internal multimachine communication, Testing BCCH, Testing RFN, Testing clock
