LMT Service ManagerThe LMT Service Manager provides the following service groupware:

� FTP server

� It can be set on the PC terminal to load and back up the files of the GGSN9811.

� FTP client

� It can upload and download software packages such as the host software.

� LMT Service Manager

� This describes the local maintenance terminal (LMT) service manager. The LMT service manager

enables the communication between the LMT software and the Switching Route Unit (SRU). In

addition, it can manage the server processes. You need not start the LMT service manager manually.

� Convert Management system

� It forwards the instruction on the alarm box by the user so that the user can operate the alarm box

through the LMT.

� Monitor Viewer tool

� It is used to query and browse monitor information of the system resources.

� Performance Browser Tool

� It is used to query and browse the information of performance management.

Version Software Package Usage� The *.cc file is a compressed file and is stored in the hard disk of SRU.

� The *.cc file contains software packets of all boards. When a board starts up, it

downloads its software packets from SRU board to its memory.

configured startup *.cc files. Then the software is loaded to the

memory and the new software runs.

Configuration Recovery

� After the SRU starts up, the configuration management

module reads configuration commands from the

configuration files and then recover the configuration

one after one.


� In the configuration files, the commands related to

interfaces cannot run immediately. The commands are

stored and start to run after the corresponding interface

board successfully registers.

Area Concepts� Main area:

� Stores the currently running software.

� Standby area:

� stores the currently running software.

� The main area and standby area can be “hd1:/soft/a ” or “hd1:/soft/b ”, it is set

by command software active.

Host Software Operation Categories� Installing the Host Software

� The default host software is installed in the device but you need to reinstall

the software in accordance with the actual requirements. Do not worry

about the service rollback as services are not started yet.

� Upgrading the Host Software

To obtain new functions or solve problems of software, you need to


� To obtain new functions or solve problems of software, you need to

upgrade your current software. You have to consider how to reduce the

affects on the service and how to perform the version rollback.

� Installing the Host Software Patch

� The patch is to provide new functions or solve problems. You have to

consider how to reduce the affects on the service and how to perform the

version rollback.

The Items to be loaded into GGSN

� To install the host software, you need to load the

host software packet, BAM, Service and XML files.

All of these files should be in the root directory of

FTP server.

� If you don’t know the IP of SRU, and can’t login GGSN by LMT, you

can use the BootRom menu to check or change the SRU IP.

Configure the FTP Server

� A. Copy the software to FTP server

� The host software files are saved in the directory D:\GGSN9811 of

the FTP server (LMT). If you store the software in other directory,

you should set that directory as the working directory of FTP user.

� The *.XML files are description files for the host software version.

When you upload the host software, these three files must be


When you upload the host software, these three files must be

saved to the same root directory of the FTP server as the

GGSN9811V900R007ENGC××B×××*.cc file and the BAM folder.

Configure the FTP Server

� B. Configure the FTP server function

� After log in to the LMT, the system starts the FTP server

automatically.

� An FTP server icon is added on the taskbar at the right

lower corner of the operating system. Right click to


configure the FTP server

� You can use other FTP server

software as well.

Check the Equipment Status

� A. Check the GGSN hardware

� LMT command: display device

� Result: every board is normal

� B. Check the GGSN software version


B. Check the GGSN software version

� LMT command: display version

� Result: the current version
