1.8 Product ReliabilityHardwareReliability

Hardware reliability lies in the following aspects.

1. Board re-power on function

When the software of a board fails to reset, implement power-off reset to the board power supply through the CSIM board.The CSIM board controls over MPIM, MPXM, WBPM and TFM,while it cannot control the other boards.

2. Board in-position detection function

Confidential and Proprietary Information of ZTE CORPORATION 11

Page 16: 1-0.B9100 Training Manual

ZXMBW B9100 Principle and Hardware Structure Training Manual

The CSIM board communicates with the other boards to judgewhether the boards run normally. To learn a more real runningstatus of the boards, the CSIM board can implement in-positiondetection of each board through the backplane or the connec-tion cable.

>> ZXMBW B9100 Work Principle

2.1 System ArchitectureArchitecture Figure 9 illustrates the ZXMBW B9100 system architecture.

FIGURE 9 SYSTEM ARCHITECTURE

Signal Flow � Forward Service

The ZXMBW B9100 receives the forward service from AGWthrough R6 interface, and implements signal coding andmodulation. After that the coded and modulated signals aretransmitted to the RRU through fiber or local connection. TheRRU performs radio modulation, amplification and filtration onthe signals, and then sends the signals to the access terminalthrough the antenna.

� Reverse Service

The antenna receives the reverse service that from access ter-minals, and passes the service to the RRU. The RRU performsradio demodulation on the service. The demodulated signals

Confidential and Proprietary Information of ZTE CORPORATION 17

Page 22: 1-0.B9100 Training Manual

ZXMBW B9100 Principle and Hardware Structure Training Manual

are transmitted to ZXMBW B9100 through fiber or local con-nection. The ZXMBW B9100 decodes the signal, and sends thesignal to core network through the R6 interface.

2.2 Signal Flows

2.2.1 Service Signal Flow

In ZXMBW B9100, the control plane signal flow and the mediaplane signal flow are combined into one signal flow.

Forward SignalFlow

Figure 10 shows the forward service signal flow.

FIGURE 10 FORWARD SERVICE SIGNAL FLOW

The service signals from the CN flows from the AGW into the CSIMboard through the R6 interface. After the signals pass the Ethernetswitch, they are distributed to MPXM, MPIM and WBPM boards toimplement MAC and PHY processing of baseband modulation. Thesignals are then sent to RRU through the baseband-RF interface.

Page 23: 1-0.B9100 Training Manual

Chapter 2 Working Principle

Reverse SignalFlow

Figure 11 shows the reverse signal flow.

FIGURE 11 RESERVE SERVICE SIGNAL FLOW

The RF signals from the MS flow into the WBPM board through thebaseband-RF interface. After the signals pass the Ethernet switch,they are distributed to the MPXM, MPIM and WBPM boards for MACand PHY processing of baseband demodulation. Finally, the signalsare sent to the AGW through the R6 interface of the CSIM board.

2.2.2 Clock Signal Flow

The ZXMBW B9100 system clock is wholly distributed by the TFMboard.

The TFM board processes the received satellite signals and outputsPP1S, 4CHIP and SerDes clock signals. Afterwards, it distributesthese clock signals to each board of the ZXMBW B9100, as shownin Figure 12.

FIGURE 12 CLOCK SIGNAL DISTRIBUTION

2.3 Power DistributionThe external -48 V power supply goes through the DC power cableto the PM panel through its panel inlet. The PM panel processesand outputs 12 V and 3.3 V into the boards in the chassis.

2.4 Ventilation and HeatDissipation PrinciplesZXMBW B9100 adopts forced air-cooling with front intake and rearexhaust. It is equipped with 3 separated fan units.

The cool air blows into the cabinet through the air intake vent atthe bottom and goes upwards through the air exhaust vent at top.

Chapter3 Networking andConfiguration

After you have completed this chapter, you will know:

>> Networking and Configuration

3.1 ZXMBW B9100 and AGWNetworking

One AGWConnected toMultiple BSs

ZXMBW B9100 supports the star networking mode with AGW, asshown in Figure 14.

FIGURE 14 ZXMBW B9100-AGW STAR NETWORKING

Each ZXMBW B9100 is connected to the AGW through the trans-mission medium. This networking mode facilitates network main-tenance and engineering installation. The signals are transferredfor very few times, so the line reliability is high.

One BS Connectedto Multiple AGWs

To improve the reliability and AGW disaster recovery capability,one BS can be connected to multiple AGWs. Both layer 2 andlayer 3 switches are supported between BS and AGWs.

1. In layer 2 mode:

One BS is connected to multiple AGWs through a layer 2 switch,as shown in Figure 15.

Confidential and Proprietary Information of ZTE CORPORATION 23

Page 28: 1-0.B9100 Training Manual

ZXMBW B9100 Principle and Hardware Structure Training Manual

FIGURE 15 BS CONNECTED TO MULTIPLE AGWS VIA LAYER 2 SWITCH

In this mode, the external IP address of MPXM is in the samesubnet as the IP addresses of the AGW interfaces. Because allmedia plane and signaling plane packets that are sent to anAGW should be transferred by the AGW interface, the corre-sponding route table must be configured in MPXM.

2. In layer 3 mode:

The external IP address of MPXM, the AGW interface IP ad-dresses, the signaling IP addresses and the media plane IP ad-dresses of AGWs can be in different subnets. In this mode, theconfiguration of MPXM is simple. The media plane and signal-ing plane packets that are sent to any AGW need to be routedonly to the external router that is connected to the MPXM.

Figure 16 shows the layer 3 mode.

4.5 GPS Antenna Feeder System

4.5.1 GPS Antenna Feeder SystemStructure

GPS signals are the reference clock and reference frequency ofthe ZXMBW B9100 system. The GPS antenna feeder system re-ceives the positioning signals from the GPS satellites. The GPSreceiver demodulates and extracts the frequency and clock sig-nals and sends them to the required units of the ZXMBW B9100.

In the case that the ZXMBW B9100 is installed indoors, the struc-ture of the GPS antenna feeder system is as shown in Figure 53.

4.5.3 GPS Feeder

The GPS feeder connects the GPS antenna and the clock moduleof ZXMBW B9100. It sends the signals that are received by theGPS antenna to the clock module for processing, and sends theDC power supply that is provided by the clock module to the GPSantenna as the working voltage.

When the GPS feeder length is shorter than 100m, adopt the 1/4"RF coaxial cable. When the GPS feeder length is longer than 100m,adopt the 1/2" RF coaxial cable.
