“NodeB LMT User Guide” describes the installation and operations of the NodeB LMT.

“NodeB Site Maintenance Guide” describes the routine hardware maintenance items of

NodeB, such as maintenance items concerning the cabinet, power supply and grounding

system, and equipment room.

“NodeB System Commissioning Guide” describes the commissioning and verification after

the installation of the NodeB.





Local maintenance:

The NodeB is maintained on the LMT through the local Ethernet port of the NodeB.

Remote maintenance:

The NodeB is maintained through the IP route provided by the RNC. The

maintenance is performed on the LMT in an RNC equipment room or on the

M2000 client in the centralized maintenance center.











Operator identity:

Operator must enter the correct user name and password to log in to the system.

Operation authority:

The system entitles different types of operators to use different command groups

for GUI or MML operations.

Operation time limit:

Each operator can operate the system only in the time period set for his/her

account.

IP address:

In local maintenance, IP addresse of the LMT PC and the NodeB local maintenance

channel (17.21.2.15) are in the same network segment.

In remote maintenance, IP address of the LMT PC is in the same network segment

with the IP address of the external network composed of the entity directly

connected to the LMT PC and the LAN where the LMT PC is located, for example,

the IP address of the RNC BAM external network.

The NodeB LMT has two lock modes:

Immediate lock

Lock by schedule

Properties of the system:

The LMT property configuration consists of the following tasks: setting the office,

setting the time-out duration of MML commands, setting the system lock time,

and running batch MML commands.



All the MML commands are in the format of "Command Word: Parameter Name=Value;".

The command word is mandatory, whereas the parameter name and value are optional.

An example of an MML command with a command word and parameters: SET ALMSHLD:

AID=10015, SHLDFLG=UNSHIELDED;

An example of an MML command with only a command word: LST VER:;



Single MML Command:

Entering an MML command in the Command Input box.

Enter an MML command in the Command Input box.

Press ENTER. The parameter show area displays the parameters of this command.

Enter the parameter values in the command parameter area.

Press F9 to run this command. The common maintenance pane displays the execution

result.



Run batch MML commands in either of the following ways

Run batch MML commands by schedule

Run batch MML commands immediately

The batch file (also referred to as the data script file) is a file in .txt format. It stores a

group of commands that can perform a common function or a specific task in a file in .txt

format. Therefore, you can simply run the file instead of entering the commands one by

one.



Fault alarm:

Alarms caused by hardware faults such as board failure, or by the abnormality of

major functions. In general, fault alarms are of higher severity than event alarms.

According to the status of the faults, fault alarms can be categorized into cleared

alarms and active alarms.

Event alarm:

An event alarm indicates a predefined event that happens during the running of

the devices. The alarm indicates an instantaneous status of the system and the

status may not be a fault. Certain event alarms are reported repeatedly and

regularly. Event alarms are not categorized into active alarms and cleared alarms.

Active alarm:

If the fault is not cleared, the status of the alarm remains Active. The alarm is called

an active alarm.

Recovery alarm:

If the fault is cleared, the status of the alarm changes to recovered. The alarm is

called a recovery alarm.



Critical Alarm：

The critical Alarm has an impact on the service provided by the system. It requires

timely handling

Major Alarm：

The major alarm affect QoS. It requires immediate handling

Minor Alarm：

The minor alarm does not affect QoS. It requires handling at a proper time against

potential faults

Warning：

The warning shows a potential error that may affect service. It may require

handling in some cases



NodeB alarms consists of the following sections:

Configuring Attributes of Alarm Browse Window

Browsing Alarms

Querying Alarm Log
