The transmit (TX) channel filters downlink signals, performs digital-to-analog conversion,
and up-converts RF signals to the TX band.
 Multiplexes receive (RX) and TX signals on the RF channel, which enables these
signals
to share the same antenna path. It also filters the RX and TX signals.
The RRU can be powered by the AC/DC power module. The RRU is called AC RRU..

Preparation before configuration
We should get all the negotiation data from customer side including common information,
Transmission information and radio information.
The engineer should negotiate about these information with customer, we can get all these
information from LLD (low level Design)
Please clear about the network topology that will be useful for trouble shooting.
There are two ways of configuring an eNodeB will be introduced in this Document
a) USING MML command
b) using XML file with GUI or LMT

Configuration of eNodeB (MML command)
1. Logging IN to eNodeB
1. Set your laptop Ethernet adapter in the same network segment as of eNodeB (ex-192.168.0.X) as the IP of UMPT for local
maintenance is 192.168.0.49.
2.Type the IP address of the Universal Main Processing and Transmission Unit (UMPT) for local maintenance in the address box of the
Internet Explorer (the default IP address is 192.168.0.49), enter the Local Maintenance Terminal dialog box is displayed
3.Fill in the User Name, Password, and Verify Code boxes. Set User Type to Local ( user name and password are admin and admin123
respectively). They are case sensitive.
4. Click Login. The LMT main window is displayed.

For eNodeB integration the transmission from enodeB to Core network should be established
To check the transmission path we need to use PING TOOL as follows:-
Change the laptop IP same as one of the DEVIP of eNodeB ex-10.202.46.42/30 and GW 10.202.46.41 (Vlan 2003)
Connect the Transmission cable to your laptop Open the ping tool and try to ping GW first .
If Ping to GW is successful than Ping M2000 or EPC IP if ping response is ok that means transmission is OK.
Now connect the cable to corresponding Port of eNodeB
Check the status of eNodeB using MML command as per next slide.

A fault alarm is generated when a hardware is faulty or a major function is abnormal. A fault alarm has a higher
severity than an event. Based on the status of the faults, fault alarms can be categorized into active alarms and
cleared alarms.
If a fault is cleared, the status of the alarm changes to cleared. This type of alarm is called a cleared alarm.
If a fault is not cleared, the status of the alarm remains active. This type of alarm is called an active alarm.
This section describes the basic concepts related to fault, event, and engineering alarms
Fault Alarm
Event Alarm
Engineering Alarm
If an NE is being installed, commissioned, upgraded, expanded, or relocated, the NE is in the engineering state.
The following are engineering alarms: alarms reported by physical or logical equipment in the engineering
state; alarms that are generated by the peer equipment but are associated with the alarms reported by the
equipment in the engineering state; cleared alarms corresponding to engineering alarms.
An event notifies users of important information when the system is running properly. Users need not handle
an event when it is generated.

Alarm Severity
The alarm severity indicates the severity of an alarm. Based on the severity, all alarms can
be categorized into four types: critical, major, minor, and warning.
Severity Definition Handling Suggestion
Critical Service-affecting condition. Critical alarms require immediate
attention, and must be cleared immediately. For example, faulty
devices are repaired or unavailable resources are restored.
Alarms must be cleared immediately. Otherwise, the
system may break down.
Major Degradation of service, not a complete loss of service. Major
alarms must be cleared during working hours. For example,
device performance and resource performance improve.
These alarms must be cleared in time. Otherwise, some
important functions cannot be implemented.
Minor Non-service-affecting condition. Minor alarms must be handled
within a certain period to avoid severer problems.
This helps maintenance personnel identify and clear
potential problems in time.
Warning Potential service-affecting condition. Warning alarms must be
cleared as required.
You only need to learn about the operating status of the
system.

Based on network management (NM) standards, alarms are categorized as follows:
Power alarm: related to the power system
Environment alarm: related to environment of the equipment room
Signaling alarm: related to service signaling
Trunk alarm: related to the transport subsystem
Hardware alarm: related to boards
Software alarm: related to software
Running alarm: related to system running
Communication alarm: related to the communication system
Integrity violation alarm: a type of security alarm, which indicates that information may be modified, added, or
removed without permission.
Operation violation alarm: a type of security alarm, which indicates that services are unavailable or unreachable due
to incorrect operations, faults, or other reasons.
Physical violation alarm: a type of security alarm, which indicates that physical resources are unavailable due to
possible attacks.
Security violation alarm: a type of security alarm, which indicates that the security service or security mechanism
detects that the system is experiencing attacks.
Time domain violation alarm: a type of security alarm, which indicates that unexpected events have occurred.
Processing error alarm: related to other exceptions.
NM Alarm Type

Browsing Active Alarms or Events On LMT
Normal alarms, events, and engineering alarms that are reported to the LMT are displayed on
the Browse Alarm/Event tab page in real time. You can view the detailed information about such
alarms or events to determine the real-time running status of the system.
Procedure
1.In the LMT main window, click the Alarm/Event tab, and then click the Browse Alarm/Event tab on the
displayed Alarm/Event tab page. The Browse Alarm/Event tab page contains Normal Alarm, Event,
and Engineering Alarm sub-tab pages.
2.View the alarm or event information on the Browse Alarm/Event tab page.
3.To determine the detailed information about an alarm or event, double-click the record of the alarm or
event. The Detailed Information dialog box is displayed.
4.In the Detailed Information dialog box, click the Solution tab to view the description, parameters, impact
on the system, system actions, possible causes, and procedure.

Querying Alarm or Event Handling Suggestions
1.Double-click an alarm on the Browse Alarm/Event or Query Alarm or Event Log tab page. The Detailed
Information dialog box is displayed.
2.In the displayed Detailed Information dialog box, click Solution. The online help of the alarm or event is
displayed.
3.View the description, parameters, impact on the system, system actions, possible causes, and procedure.
4.Click in the upper right corner of the online help to exit the online help.

Alarms are recorded and stored on NEs. If the M2000 is available, NEs also report alarms to the M2000
server for storage. Alarm collection on the NE side is to collect alarm logs. Alarm information of a single NE
or all NEs managed by the M2000 can be obtained on the M2000.
Collecting Alarm Information on M2000
Step :1 Open the Alarm Query Window
Choose Monitor> Browse Current Alarm on M2000

Step :2 In the displayed Filter window set query condition
Set filter criteria in the Basic Setting dialog box to query alarms
meeting conditions.
Severity: indicates the severity of alarms. Options include critical,
major, minor, and warning. You can select a severity as required.
All options are selected by default.
Status: indicates the alarm status. "Cleared" and "Uncleared"
indicate whether alarms are cleared while "Acknowledged" and
"Unacknowledged" indicate whether alarms are confirmed by the
administrator. All options are selected by default.
Type: indicates the type of alarm information. All options are
selected by default.
Alarm query results can be filtered based on the alarm generation
time and alarm clearance time.
Recent alarms can be queried by minute, hour, or day.
Collecting Alarm Information on M2000 Cont’d

After setting all parameters, click OK.
In the Alarm Source dialog box, select NEs to be queried, set Select to Custom, click Add and select NE from the
displayed menu, and then select NEs in the displayed dialog box. +

Step 3: Save query results.
In Alarm Information window, right-click an entry and choose Save All Records from the shortcut
menu, and then save the results to an .XLS file.
.
Note: If the OMCH between the NE and the M2000 is disconnected for some time, alarms of the NE are incomplete on
the M2000. In this case, manually synchronize alarms of the NE by choosing Monitor > Synchronize NE Alarm.
