1 Product Position and Features1.1 Product Position

The DBS3900 is used for radio access in the LTE system. The DBS3900 mainly performs

Radio Resource Management (RRM) functions such as air interface management, accesscontrol, mobile control, and User Equipment (UE) resource allocation.

The DBS3900 has two types of basic modules: enterprise baseband unit (eBBU) andenterprise remote radio unit (eRRU),Figure 1-1 shows the position of the DBS3900 in thewhole system.

1.2 Product Features

Supporting Multiple Frequency Bands

DBS3900 supports frequency bands such as 1.8 GHz, 1.4 GHz, 400 MHz, 800 MHz, 2.3 GHz,and 3.5 GHz, which meets the requirements of multiple frequency bands.

Distributed Architecture

In the distributed architecture, the BBU and RRU of an DBS3900 are separately deployed and

connected through fibers. This minimizes feeder loss and improves eNodeB coverage. Thedistributed BBU+RRU architecture allows RRUs to be mounted on walls or to poles, enabling

zero footprint site deployment. As a result, network deployment costs can be reduced by morethan 30% and network deployment efficiency is significantly improved.

Excellent PerformanceMaximum bit rates per TDD cell are up to100 Mbit/s downlink and 50 Mbit/s uplink over 20

MHz wide channels. The excellent performance can help customers preempt the commandingelevations of the professional mobile broadband industry and get rapid service expansion.

Flexible Networking

The DBS3900 supports varied frequency bands, enabling customers to provide services over

both readily and newly available frequency bands. Customers can utilize more than twofrequency bands on one wireless network based on the availability of frequency resources indifferent areas.

Energy-saving Base Station

RRUs are the most energy-consuming units of an eNodeB. Thanks to the cutting-edge

hardware design of power amplifiers and the use of innovative power amplifier andconsumption management technologies, the RRUs consume 40% less power than similar

products from other vendors.

Anti-network Paralysis

The DBS3900 supports "Fallback mode". When the Core Network Device is down, the eBBU

starts the CNPU which works as a Core Network; it will ensure that all the services under the

eNodeB work normal.

Product Description 2 Product Structure

2 Product Structure2.1 Overview

The DBS3900 features a distributed architecture and is comprised of two types of basicmodules: eBBU (enterprise Baseband control unit) and eRRU (enterprise remote radio unit).The eBBU and eRRU transmit CPRI signals via fiber optic cables that connect them through

common public radio interface (CPRI) ports. This kind of architecture satisfies therequirements of setting up enterprise wireless communication networks.

2.2 Basic Module

2.2.1 eBBU

The eBBU, a baseband unit, performs the following functions:

Provides ports for connection to the core network and processes related transmissionprotocols.

Provides CPRI ports for communication with eRRUs and processes uplink and downlinkbaseband signals.

Manages the entire base station by means of operation and maintenance (OM) andsignaling message processing.

Provides an OM channel towards the local maintenance terminal (LMT) or eOMC.

Provides clock ports for clock synchronization, alarm monitoring ports for environment

monitoring, and a Universal Serial Bus (USB) port for commissioning the use of a USBstorage device.

1. eBBU exterior

The eBBU has a compact case structure measuring 19 inches wide and 2 U high. Figure2-1 shows the eBBU exterior.

Figure 2-1eBBU exterior

2. Boards of the eBBU

The eBBU is configured with the following mandatory boards and modules:

LTE main processing and transmission unit (LMPT): Manages the entire E-UTRANNodeB (eNodeB) in terms of OM, processes signaling, and provides clock signals for theeBBU.

LTE baseband processing unit (LBBP): Processes baseband signals and CPRI signals.

Baseband boards in eLTE3.3 support only D boards. If C boards are used, basebandboards in eLTE3.1 are required.

CNPU (Core network processing unit): Provides fallback mode capability.

Fan unit (FAN): Controls the rotation of fans, checks the temperature of the fan module,and performs heat dissipation for the BBU.

Universal power and environment interface unit (UPEU): Converts -48 V DC power into+12 V DC, and provides ports for transmission of two RS485 signal inputs and eightBoolean signal inputs.

"Fallback mode" means that when the Core Network Device is down, the eBBU starts the CNPU whichworks as a Core Network, it will ensure that all the services under the eNodeB work normal. CNPU is anoptional board.

Product Description 5 Operation and Maintenance



21

5 Operation and Maintenance5.1 Overview

The DBS3900 supports the O&M system that is based on the man-machine language (MML)and the graphic user interface (GUI). The O&M system enables a hardware-independentO&M mechanism and provides powerful O&M functions for users to meet various O&M

requirements.

5.2 Characteristics

Robust Hardware Management, Rapid Fault Location and Rectification

DBS3900 hardware management provides pre-warning mechanism and resetting mechanismto make sure sufficient time are left for troubleshooting before service interruptions. Recoverycan be implemented by resetting to avoid severe accidents in case faults cannot be cleared intime. When a hardware fault occurs, the DBS3900 alerts the user by generating alarms and

flashing indicators and provides suggestions to guide the user in troubleshooting. After thefault is recovered, the alarm is cleared.

Advanced Software Management and Smooth Upgrade

DBS3900 software management provides upgrade and rollback mechanism, which allows a

software version upgrade and rollback to another version. The upgrade process includesdownloading software files to the OMU using the Security File Transfer Protocol (FTPS)

server, loading the software from the OMU to the flash of each board, and activating thesoftware in the board flash. This process does not affect other services and adopts theprotection mechanism to raise the success rate of switching. The effect on available resourcesis reduced to the lowest level.

Key data is backed up in the process of upgrading. Therefore, a rollback can be generatedimmediately when upgrade fails, and the system recovers to a normal state in a short time.

After the upgrade is complete, version consistency check is performed to verify the versioncorrectness.

Rich Tracing and Detection Functions

DBS3900 provides hierarchical tracing and detection functions, including user tracing,interface tracing, message tracing, fault detection on the physical layer, fault detection on the

data link layer, and other fault detection functions, facilitating fault locating. The tracinginformation can be saved into files and be checked using the tracing retrospection tool.
