About This ManualPurposeWith the development of the communication technology, operators have more variedrequirements on the Operation & Maintenance Center (OMC). When adjusting the BaseTransceiver Station (BTS) equipment on-site, the engineers may need to observe theBTS feedback and fine tune the equipment parameters. To cater for the requirement, theLocal Maintenance Terminal (LMT) is developed.
Through the LMT function, the operation & maintenance engineers can use a networkcable to connect to the control board of the BTS, and then telnet to the BTS to perform thequerying and setting operation.
This manual gives a detailed description of the LMT basic concepts, functions, and theLMT commands.
Intended AudienceThis manual is intended for:
l Operation & maintenance engineers at the Code Division Multiple Access (CDMA)base station
l CDMA network optimizing engineers

1.1 LMT System FunctionLocal Maintenance Terminal (LMT) is a featured function of the ZTE's Code DivisionMultiple Access (CDMA) base station system.
In virtue of this function, the filed engineers at the Base Transceiver Station (BTS) canuse a notebook (or the maintenance PC terminal in the equipment room) to telnet to theBTS control board (CCM, for example) via the Ethernet, and input the LMT commands toimplement the operation and maintenance for the BTS. It enables the engineer to operatethe BTS without login to the Operation & Maintenance Module (OMM) and facilitates theBTS maintenance.
To fulfill this function, the notebook (or the maintenance PC terminal in the equipmentroom) only needs to use its built-in Telnet function and install the 3GDownload tool whichis provided by ZTE. It is unnecessary to install other software.
ZXC10 BSSB LMT provides the following functions:
l Enters and cancels LMT mode.l Self-starts a BTS.l Downloads BTS board software version and configuration data locally.l Queries BTS current alarm information.l Performs diagnostic tests on boards.l Supports the RF control functions, including:
à Starts and stops the auto-scaling.
à Queries and sets the RF power.
à Queries the Receive Signal Strength Indicator (RSSI).
1.2 LMT Software Module CompositionThe ZXC10 BSSB LMT is composed of the following two software modules:

1.3 Connection Between an LMT and a BSS NEFigure 1-1 displays the connection between an LMT and a BSS NE.
Figure 1-1 LMT Connection
Through an LMT, the operation and maintenance engineer can use a network cable toconnect to the control board of an NE and then telnet to the NE to perform the queryingand setting operations.
1.4 BTS Startup ModeThere are the following two startup modes for the BTS:
l Base Station Controller (BSC) startup model LMT startup mode
All the commands except those related to mode configuration are applicable in both themodes while sharing all the functions.
BSC Startup Mode
The BTS requires necessary software version and relevant configuration data from theBSC during its startup.
1-2
SJ-20110707103919-022|2011-12-30 (R1.1) ZTE Proprietary and Confidential
Chapter 1 LMT Overview
BSC startup mode is suitable for the situation in which the communication at the Abisinterface between the BTS and the BSC is normal. This is the default startup mode for theBTS.
Note:
When the BTS is in BSC startup mode, it cannot be switched to LMT startup mode.
LMT Startup Mode
The BTS starts up and operates with necessary software version and relevant configurationdata without requiring these from BSC.
LMT startup mode is suitable when the communication at the Abis interface between theBTS and the BSC is interrupted. Communication interruption at Abis interface refers tothe situation in which the functional board (such as the DSM board) is not powered on ortransmission interruption occurs between the BTS and the BSC.
Note:l LMT startup mode cannot be configured for the BTS when the communication at Abis
interface is normal.l Under LMT startup mode, the operators must restart the BTS after completing the
operations on the BTS. By not restarting BTS after operating it under LMT startupmode, any further operation on the BTS on the OMM cannot be performed, even ifthe communication at the Abis interface is normal afterwards.
1.6.1 3GDownload Software Tool FunctionThe 3GDownload software tool is used not only to download the required BTS softwareversion and the configuration data, but also to create the Operation & MaintenanceProcessor (OMP) version information file of the BSC and create the version template.The following part will introduce the functions of the 3GDownload software tool, including:l generating the version template filel downloading the board software of the entire equipmentl configuring the OMP startup information filel obtaining the ZDB files from the BTS
1.6.2 Generating a Version Template FileWhen upgrading and maintaining the base station software, the engineers can use theZXC10BSSB LMT to automatically scan the version directory in order to generate a versiontemplate file. The template file can be used in the version comparison. With this function,the engineers can easily check whether the version of an NE is correct.
Context
The version template file consists of the BSC version information and the BTS versioninformation.
Steps
1. Double-click LMT.exe. The ZXC10 BSSB LMT dialog box is displayed.
2. Click 3G Download. The main window is displayed, see Figure 1-2.

Note:l The root directory of Path of the release must contain the Release
directory. Otherwise, the program may report errors automatically.l If the user has selected the Release version directory to be scanned, the paths
of the configuration files are automatically positioned to the Release directory.The system automatically cuts the upper-level directory names of Release asthe file names. Both the storage path and the file names can be modified.
l Path of the release and Path of the excel created directories can be modifiedonly after clicking the Browse button. These two directories cannot be directlymodified.
l During the process of generating a template file, exit the Excel program to avoiderrors.
5. After configuring the paths, click OK. A success message box is displayed. Click OK.
Note:
The template file generation might last more than 60 seconds, please be patient.
6. Navigate to the directory for saving the version template file. Open the file to view it,see Figure 1-4.
