9 OM Subsystem of the BTS3812E

About This Chapter

The OM subsystem of the BTS3812E manages, monitors, and maintains the software, hardware,and configuration of the NodeB. The OM subsystem provides various OM modes and multiplemaintenance platforms to meet different maintenance requirements.

9.1 OM Modes of the BTS3812EThe BTS3812E supports three maintenance modes: local maintenance, remote maintenance, andreverse maintenance.

9.2 Functions of the BTS3812E OM SubsystemThe OM subsystem of the BTS3812E provides the functions of the commissioning management,equipment management, software management, and alarm management.

9.1 OM Modes of the BTS3812EThe BTS3812E supports three maintenance modes: local maintenance, remote maintenance, andreverse maintenance.

The OM subsystem provides three maintenance modes as follows:

l Local maintenance: The NodeB is maintained on the LMT through the local Ethernet portof the NodeB.

l Remote maintenance: The NodeB is maintained through the IP route provided by the RNC.The maintenance is performed on the M2000 client or the LMT in an NMS center or anRNC equipment room.

l Reverse maintenance: Another NodeB is maintained on the LMT through the local Ethernetport of a local NodeB and the IP route is provided by the RNC.

NOTE

After hardware installation, the NodeB is loaded with only the software, not the data configuration file. Inthis situation, an IPoA maintenance channel with parameters negotiated between the NodeB and the RNCin the ATM transport network can be automatically set up. This function enables maintenance personnelto download the data configuration file to the NodeB at the far end.

Components of the NodeB OM Subsystem

l LMT: maintains a single NodeB.

l M2000: maintains multiple NodeBs.

l RAN configuration system: provides data configuration for Huawei RNC and NodeB.

l OM channel: provides channels between the NodeB and the LMT and between the NodeBand the M2000.

l Network Element (NE): refers to the object of maintenance.

9.2 Functions of the BTS3812E OM SubsystemThe OM subsystem of the BTS3812E provides the functions of the commissioning management,equipment management, software management, and alarm management.

Commissioning ManagementCommissioning management provides the following functions:

l Equipment performance test: CPU occupancy test, clock source quality test, and power test

l Routine test: E1/T1 performance test and the STM1 performance test

l Service performance test: RF performance test, UL channel scanning, and service resourceoccupancy statistics

Equipment ManagementThe equipment management consists of the equipment maintenance and data configuration.

l Maintaining the equipment: board reset, equipment status management, equipment self-testing, active/standby switchover, and time correction

l Configuring the equipment: configuring, querying and backing up equipment parameters,such as the NodeB hardware, clock, algorithm, and RF parameter configuration

Software ManagementSoftware management provides the following functions:

l Activating the software

l Checking the compatibility of software and hardware versions

l Querying hardware and software versions

l Upgrading the software version

Alarm ManagementAlarm management consists of equipment alarm management and environment alarmmanagement.

l The alarm management system of the BTS3812E can detect and report equipment faultsin real time. The LMT or the M2000 can display alarm information and provide alarm-handling suggestions.The alarm management system of the M2000 connects to an alarm box through a serialport and supports both audible and visible alarms. The alarms can be subscribed by usersand forwarded to the handsets or pagers of maintainers so that the faults can be handled intime.

l Environment alarm managementTypically, the equipment rooms are unmanned and distributed over a vast area. Theequipment in such a room works in a relatively adverse environment, which may incurfires, water immersion, or flood. To help you handle such emergencies, the NodeB providesa complete alarm monitoring system.

Alarm management provides the following functions:

l Alarm testing

l Alarm reporting

l Alarm shielding

l Alarm affirming

l Alarm pre-processing

l Alarm correlation processing

l Alarm help information processing

Right ManagementThe operation rights for maintainers are divided into multiple levels when both the BTS3812Esand the M2000 are applied. This ensures that the running equipment is free from misoperation.

Environment MonitoringThe NodeB provides a complete environment monitoring system to help you handleemergencies.

The environment monitoring system provides customized solutions regarding door control,infrared, smoke, water immersion, humidity, and temperature.
