4 Topologies of the DBS3800

About This Chapter

This describes the topologies of the NodeB, which consists of the networking on the Iub interface

and networking on the CPRI interface.

4.1 Network Topologies on the Iub Interface

When ATM transport is applied, the NodeB supports multiple topologies on the Iub interface,

such as star, chain, and tree. When IP transport is applied, the NodeB supports the star topology.

4.2 Topologies on the CPRI Interface

Multiple topologies such as star, chain, and ring are supported between the BBU and RRU.

DBS3800

Product Description 4 Topologies of the DBS3800



21



4.1 Network Topologies on the Iub Interface

When ATM transport is applied, the NodeB supports multiple topologies on the Iub interface,

such as star, chain, and tree. When IP transport is applied, the NodeB supports the star topology.

Figure 4-1 shows the typical topologies of the NodeB.

Figure 4-1 Typical topologies

NOTE

l The CPRI port on the BBU supports the transmission at a rate of only 1.25 Gbit/s.

l The above figure takes BBU3806 as an example.

l In the chain and tree topologies, the NodeB can support up to five levels of cascading.

4.1.1 Star Topology

As the most commonly used topology, the star topology applies to most areas, especially to

densely populated areas.

Figure 4-2 shows the star topology.

DBS3800




22



Figure 4-2 Star topology

Advantages:

l The NodeB is directly connected to the RNC. Therefore, its simplicity makes it convenient

to maintain, engineer, and expand.

l Direct data transmission is built between the NodeB and the RNC. This makes signals travel

through fewer nodes, which gives higher transmission reliability.

Disadvantage: Compared with other topologies, the star topology requires more transmission

resources.

4.1.2 Chain Topology

The chain topology applies to the belt-shaped and sparsely populated areas, such as highways

and railways.

Figure 4-3 shows the chain topology.

DBS3800




23



Figure 4-3 Chain topology

Advantage: The chain topology can reduce costs in transmission equipment, engineering,

construction, and the transmission link lease.

Disadvantages:

l Signals travel through many nodes, so the transmission reliability is low.

l Faults in the upper-level NodeB may affect the lower-level NodeB(s).

l The number of levels in the chain topology cannot exceed five.

4.1.3 Tree Topology

The tree topology applies to complicated networks and sites such as a large area with

concentrated hot spots.

Figure 4-4 shows the tree topology.

Figure 4-4 Tree topology

Advantage: The tree topology requires fewer transmission links than star topology.

Disadvantages:

DBS3800




24



l Signals travel through many nodes, which causes low transmission reliability and

difficulties in maintenance and construction.

l Faults in the upper-level NodeB may affect the lower-level NodeB(s).

l Capacity expansion is difficult because it may involve major modification to the network

structure.

l The number of levels in the tree topology cannot exceed five.

4.2 Topologies on the CPRI Interface

Multiple topologies such as star, chain, and ring are supported between the BBU and RRU.

Figure 4-5 shows the typical topologies between the BBU and the RRU.

5 Clock Synchronization Modes of the

DBS3800

The DBS3800 supports five clock synchronization modes: line clock, GPS clock, BITS clock,

IP clock, and internal clock.

Line Clock

The BBU directly extracts clock signals from the Iub interface such as the E1/FE interface. Then,

the BBU outputs the precise 2.048 MHz and 8 kHz clocks after frequency dividing, phase

locking, and phase adjusting. The 2.048 MHz and 8 kHz clocks are used for frame

synchronization and bit synchronization in the DBS3800.

NOTE

l The BBU3806 V100R011 and later directly extracts the Line clock from the E1/FE port.

l The BBU3806 V100R010 and before can not directly extracts the Line clock from the FE port.

l In DBS3800 V100R012 and later versions, when active and standby BBU3806s are interconnected,

the line clock must be configured on the active BBU3806.

GPS Clock

The BBU provides the input port for the GPS clock and obtains the clock through the external

GPS device. This enables the BBU to receive GPS clock signals when the upper-level clock is

unstable or unavailable.

BITS Clock

The BBU3806 supports the BITS clock mode by providing a port for the 2.048 MHz BITS clock.

NOTE

The BBU3806C does not support the BITS clock mode.

IP Clock

Without requirements for additional hardware, the IP clock is supported through software

upgrade, providing IP transport with cost-effective clock solutions.

DBS3800

Product Description 5 Clock Synchronization Modes of the DBS3800



26



Internal Clock

The clock module of the BBU uses the oven controlled crystal oscillator (OCXO) to achieve

high stability and performance. The combination of advanced algorithms and software phase-

lock technique ensures high accuracy of the clock. The frequency accuracy of the clock system

meets the requirement stipulated in the 3GPP TS 25.104 and 3GPP TS 36.104 protocols. In the

absence of external clocks, the internal clock can ensure that the NodeB works normally for at

least 90 days and its precision can be higher than 0.05 ppm.

Product Description 7 Operation and Maintenance of the DBS3800



51



7.1 OM Modes of the DBS3800

The DBS3800 supports local maintenance, remote maintenance, and reverse maintenance.

The OM subsystem provides the following three maintenance modes:

l Local maintenance: The NodeB is maintained on the Local Maintenance Terminal (LMT)

through the local Ethernet port of 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 a Network Management

System (NMS) center or an RNC equipment room.

l Reverse maintenance: An additional NodeB is maintained on the LMT through the local

Ethernet port of a local NodeB, and the IP route is provided by the RNC.

NOTE

The OM subsystem of the NodeB supports the automatic setup of default maintenance channel. After

hardware installation, the NodeB can automatically set up a maintenance channel to the RNC on the ATM

network. Through this channel, the maintenance personnel can remotely download data and programs to

the NodeB, which enhances the network maintainability.

Figure 7-1 shows the OM subsystem of the NodeB.

Figure 7-1 OM subsystem of the NodeB

The OM subsystem of the NodeB consists of the following components:

l LMT: used to maintain single NodeB.

l M2000: used to maintain multiple NodeBs.

l OM channel: provides channels between the NodeB and the LMT and between the NodeB

and the M2000.

l NE: refers to the object maintained.

DBS3800




52



7.2 OM Functions of the DBS3800

The DBS3800 provides OM functions such as commissioning management, equipment

management, software management, and alarm management.

Commissioning Management

Commissioning management provides the following functions:

l Equipment performance tests, such as the CPU usage test, the clock source quality test, and

the power test

l Routine tests, such as the E1/T1 performance statistics and the STM-1 performance

statistics

l Service performance tests, such as the 141 test, the uplink channel scanning, and the

statistics for service resource usage

Equipment Management

The equipment management involves the equipment maintenance and the data configuration.

l The equipment maintenance provides the maintenance of equipment or boards, for

example, resetting boards, managing the status of equipment, performing self-check on the

equipment, performing an active/standby switchover, and calibrating the clock.

l The data configuration provides configuration, query, and backup for the equipment

parameters, for example, configuring the parameters of the NodeB clock, algorithm

parameters, or RF parameters.

Software Management

Software management provides the following functions:

l The software activation

l Checks the compatibility of software and hardware versions

l The version management, for example, querying hardware and software versions

l Upgrades the software version

Alarm Management

The alarm management involves the equipment alarm management and the environment alarm

management.

l Equipment alarm management

The alarm management system detects and reports information about faults in real time.

The LMT or M2000 then displays the alarm information and provides appropriate handling

suggestions.

The alarm management system of the M2000 connects to an alarm box through a serial

port and supports both audio and visual alarms as in the LEDs or the alarm box. The

maintenance personnel can subscribe to specific alarms. When related alarms are generated,

DBS3800




53



the alarm information is forwarded to the handsets or pagers of the maintenance personnel

so that they can rectify the faults in time.

l Environment alarm management

The environment alarm management is intended for the equipment room of NodeBs.

Typically, the equipment rooms are unmanned and distributed over a vast area. The

equipment works in a relatively adverse environment, and fire, water immersion, or

flooding may occur. To help you handle such emergencies, the NodeB provides a complete

alarm monitoring system.

Alarm management provides the following functions:

l Alarm detection

l Alarm report

l Alarm shielding

l Alarm acknowledgement

l Alarm preprocess

l Alarm correlation process

l Alarm help process

Security Management

The access rights for maintenance personnel are classified into multiple levels when both NodeB

and M2000 are applied. This ensures that the equipment in use is free from mishandles.

Environment Monitoring

To help you handle emergencies for normal operation of the equipment, the NodeB provides a

complete environment monitoring system.

The environment monitoring system provides customized solutions regarding door control,

infrared, smoke, water immersion, humidity, and temperature.
