3BTS3900 Hardware ConfigurationAbout This Chapter

This section describes the cabinet, power system, transmission system, CPRI port, and

monitoring system configurations of the BTS3900, and provides reference for planning and

deploying theBTS3900.

3.1 Board and Module Configurations

This chapter describes the configuration principles of the boards and modules in the cabinet.

3.2 Combinations of Cabinets

The BTS3900 cabinets can be stacked or installed side by side. The side-by-side installation

mode is recommended. If the space in the equipment room is insufficient, the stack mode can

be used.

3.3 Power System of the BTS3900

The BTS3900 supports 110 V AC, 220 V AC, and -48 V DC power supplies. When AC power

is supplied, the power is converted to -48 V DC power for the base station.

3.4 BTS3900Monitoring System

The BTS3900 monitoring system monitors all boards and components in the cabinet. If any

board or component is faulty, an alarm is reported automatically. The alarm signals are collected

both inside and outside the cabinet by the UPEU, UEIU, or EMU, so that the entire site can be

monitored.

The BTS3900 cabinets can be stacked or installed side by side. The side-by-side installationmode is recommended. If the space in the equipment room is insufficient, the stack mode can

be used.

Side-by-Side Installation Mode

The principles for installing two cabinets side by side are as follows:

l By default, the primary cabinet is positioned on the left, and the secondary cabinet is

positioned on the right. If restricted by the actual situation in the equipment room, the

primary cabinet canbe positioned onthe right.

l The BTS3900 (-48 V DC) cabinet, BTS3900 (+24 V DC) cabinet, and BTS3900 (AC)

cabinet support side-by-side installation mode.NOTE

l The primary cabinet is the cabinet that is configured with the BBU.

3.4 BTS3900 Monitoring System

The BTS3900 monitoring system monitors all boards and components in the cabinet. If anyboard or component is faulty, an alarm is reported automatically. The alarm signals are collected

both inside and outside the cabinet by the UPEU, UEIU, or EMU, so that the entire site can be

monitored.

3.4.1 BBU Monitoring Port

3.4.2 Configuration of the Monitoring System

The BTS3900 cabinet is managed by the monitoring boards, such as the FMU and PMU. A

monitoring board is connected to the MON port on the BBU. It collects the alarms of all

components and reports the alarms to the BBU through the RS485 serial bus.

3.4.3 Customized Alarm Inputs

Customized alarms must be reported to the BBU.

3.4.1 BBU Monitoring Port

The BBU houses the UPEU and UEIU for monitoring. Each board has two Boolean input ports

and two RS485 input ports, and each Boolean input port receives four Boolean inputs. Figure

3.4.2 Configuration of the Monitoring System

The BTS3900 cabinet is managed by the monitoring boards, such as the FMU and PMU. A

monitoring board is connected to the MON port on the BBU. It collects the alarms of all

components and reports the alarms to the BBU throughthe RS485 serial bus.

l For details about the monitoring ports on the FMU, see 4.5.2 FMU. The FMU is configured

in the BTS3900 cabinet (-48 V DC), BTS3900 cabinet (+24 V DC),and BTS3900 cabinet

(AC). For details about the position of the FMU in the cabinet, see 3.1.1 Module

Configurations in the Cabinetand 4.5 Fan Unit.

l For details about the monitoring ports on the PMU, see 4.9.2 PMU. The PMU is configured

in the BTS3900 cabinet (AC). For details about the position of the PMU in the cabinet, see

3.1.1 Module Configurations in the Cabinet.

Monitoring Principle for the BTS3900 Cabinet (-48 V DC)

A maximum of three BTS3900 cabinets can be configured for a single site. The monitoring

system described in this part is applicable to the configuration of three cabinets. If there is only

one cabinet at the site, neglect cabinet 1 and cabinet 2 and their cable connections. If there are

two cabinets at the site, neglect cabinet 2 and its cable connection. If any device in the figure is

not configured at the site, neglect the device and its cable connection.

3.4.3 Customized Alarm Inputs

Customized alarms must be reported to the BBU.

Customized alarms are reported to the BBU by any of the following methods:

l The alarms are collected by the UPEU or UEIU in the BBU.

l The alarms are collected by the EMU.

For details about the configuration of the customized alarms, see the related initial configuration

guide.

Monitoring Board Configuration

The configurations of the monitoring boards in the BTS3900 depend on the number of

customized alarms, as listed in Table 3-7.

l If power backup is required for the BBU, two UPEUs are configured instead of a UPEU and a UEIU.

l If three BTS3900 cabinets are configured, only one UEIU is required to monitor both RS485 and dry

contact alarms.

l Analog values can be monitored only by the EMU.

l The EMU with sensors can be configured according to site requirements.

Customized Alarms Collected by the UPEU or UEIU

Each UPEU or UEIU in the BBU supports eight Boolean signal inputs. A UPEU and a UEIU

or a maximum of two UPEUs can be configured for a BBU to receive 16 Boolean signal inputs.

This method can be used for the configuration of fewer than 16 customized alarm inputs. The

method to collect customized alarms using the UPEU or UEIU is shown in Figure 3-20.

If there are more than 16 Boolean signal inputs, the EMU can be configured for the BTS3900.

Each EMU supports 32 Boolean signal inputs and two RS485 signal inputs, the cable connections

are shown in Figure 3-21.

l The cable connection of the EMU in the BTS3900 cabinet (-48 V DC) and BTS3900 cabinet

(+24 V DC): The EMU is connected to the MON1 port on the UPEU in the BBU.

l The cable connection of the EMU in the BTS3900 cabinet (AC): The EMU is connected

to the right RS232/RS422 port on the PMU in the AC/DC power system.

4BTS3900 ComponentsAbout This Chapter

This section describes the BTS3900 components, which are the BBU, DCDU-01, Fan Box, RFU,

GATM, EMU, ELU, power system, and PS4890 components.

4.1 BBU3900Equipment

The BBU3900 is used for baseband processing and enables interaction between the BTS and

the BSC.

4.2 DRFU

The Double Radio Frequency Unit (DRFU) is a dual-density RF unit. A DRFU processes two

carriers.

4.3 GRFU

The GSM Radio Frequency Unit (GRFU) is designed on the basis of multi-transceiver

technology. One GRFUsupports 6 carriers outputs.

4.4 DCDU-01

The Direct Current Distribution Unit-01 (DCDU-01) supplies DC power to each component in

the cabinet.

4.5 Fan Unit

A fan unit contains a fan subrack, four fans, and an FMU.

4.6 GATMThe GSM Antenna and TMA control Module (GATM) controls the antenna and TMA.

4.7 ELU

The Electronic Label Unit (ELU) reports the cabinet type information to the fan box.

4.8 Power Equipment (DC/DC)

The power equipment (DC/DC) converts +24 V DC power into -48 V DC power.

4.9 Power Equipment (AC/DC)

The power equipment (AC/DC) converts 220 V AC power into -48 V DC power.

4.1 BBU3900 Equipment

The BBU3900 is used for baseband processing and enables interaction between the BTS and

the BSC.

The primary functions of the BBU3900 are as follows:

l Provides physical ports for the communication between the BTS and the BSC

l Provides CPRI ports for the communication with the RF modules

l Provides USB ports for downloading the BTS software

l Provides the OM channel for connection with the webLMT or the M2000

l Processes uplink and downlink data

l Provides centralized management system on the entire DBS system, such as OM and signal

processing

l Provides the reference clock for the system

The Electronic Serial Number (ESN) is unique to a network element (NE) for identification, and

is used during the commissioning of the base station.

l If there is a label on the FAN unit of the BBU, the ESN is printed on a label and the mounting

ears of the BBU. Figure 4-2shows the position of the ESN.
