3.2 Combinations of CabinetsThe 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 canbe used.

Side-by-Side Installation ModeThe 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, theprimary cabinet can be positioned on the 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.

l The secondary cabinet is the cabinet that is not configured with the BBU.

Figure 3-7, Figure 3-8, and Figure 3-9 show the side-by-side installation mode with twocabinets.

Power Distribution Scheme of the BTS3900 Cabinet (-48 V DC)

When the BTS3900 cabinet uses -48 V DC power supply, the DCDU-01 provides 10 DC powerinputs to the modules in the cabinet. Figure 3-13 shows the power distribution scheme of theBTS3900 cabinet (-48 V DC). Like the power distribution scheme of a single cabinet, twocabinets are supplied by the external power device.

Figure 3-13 Power distribution scheme of the BTS3900 cabinet (-48 V DC)




Issue 12 (2011-03-30)

NOTE

MCB: miniature circuit breaker

Power Distribution Scheme of the BTS3900 Cabinet (+24 V DC)When the BTS3900 cabinet uses +24 V DC power, the DC/DC power device converts +24 VDC power into -48 V DC power and feeds -48 V DC power to the DCDU-01. Then, the DCDU-01feeds power to each module in the cabinet. Figure 3-14 shows the power distribution schemeof the BTS3900 cabinet (+24 V DC). Like the power distribution scheme of a single cabinet,two cabinets are supplied by the external power device.

Figure 3-14 Power distribution scheme of the BTS3900 cabinet (+24 V DC)

Power Distribution Scheme of the BTS3900 Cabinet (AC)When the BTS3900 cabinet uses 220 V AC three-phase power, 220 V AC single-phase power,or 110 V AC dual-live-wire power, the AC/DC power device converts the AC power into -48V DC power and feeds -48 V DC power to the DCDU-01. Then, the DCDU-01 feeds power toeach module in the cabinet. Figure 3-15 shows the power distribution scheme of the BTS3900cabinet (AC). Like the power distribution scheme of a single cabinet, two cabinets are suppliedby the external power device.

3.4 BTS3900 Monitoring SystemThe 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 collectedboth inside and outside the cabinet by the UPEU, UEIU, or EMU, so that the entire site can bemonitored.

3.4.1 BBU Monitoring Port

3.4.2 Monitoring Principles of the CabinetThe BTS3900 cabinet is managed by monitoring boards, such as the FMU and PMU. Eachmonitoring board is connected to the MON port on the BBU. They collect alarms of allcomponents and report the alarms to the BBU by using the RS485 serial bus.

3.4.3 Customized Alarm InputsWhen an alarm is generated by the customized equipment, the alarm must be reported to theBBU.

3.4.1 BBU Monitoring PortThe BBU houses the UPEU and UEIU for monitoring. Each board has two Boolean input portsand two RS485 input ports, and each Boolean input port receives four Boolean inputs. Figure3-16 shows the slot assignment for the UPEU and UEIU.

3.4.2 Monitoring Principles of the CabinetThe BTS3900 cabinet is managed by monitoring boards, such as the FMU and PMU. Eachmonitoring board is connected to the MON port on the BBU. They collect alarms of allcomponents and report the alarms to the BBU by using the RS485 serial bus.

For details about functions of the monitoring ports on the FMU, see 4.5 Fan Box. The FMU isconfigured in the BTS3900 (-48 V DC), BTS3900 (+24 V DC), and BTS3900 (AC). For detailsabout the position of the FMU in the cabinet, see 3.1.1 Module Configurations in theCabinet and 4.5 Fan Box.

Following is based on two BTS3900 cabinets. If Cabinet 1 shown in the following figure is notconfigured at a site, the related monitoring signal cables are also not configured.

NOTE

For details about how to monitor the EMU, see the section Customized Alarm Inputs.

3.4.3 Customized Alarm InputsWhen an alarm is generated by the customized equipment, the alarm must be reported to theBBU.

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 configurationguide.

Monitoring Board Configuration

The configuration of the monitoring boards in the BTS3900 depends on the number ofcustomized alarms, as listed in Table 3-7.

l If backup power is required for the BBU, two UPEUs rather than UPEU+UEIU are configured.

l If three BTS3900 cabinets are configured, only one UEIU is required to monitor both RS485 and drycontact 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 alarm inputs. A maximum of twoUPEUs or UPEU+UEIU can be configured for the BBU to receive 16 Boolean alarm inputs.This method can be used for the configuration of fewer than 16 customized alarm inputs. Themethod to collect customized alarms by using the UPEU or UEIU is shown in Figure 3-20.

The DRFU performs modulation and demodulation of baseband and RF signals, processes data,combines and divides the signals.

Both the DRFU of 900 MHz and DRFU of 1800 MHz perform the following functions:

l Adopts the direct frequency conversion technology, modulates the baseband signals to theGSM TX band. After filtering and amplification, the baseband signals are transmitted tothe antenna system through the duplex filter.

l Receives uplink RF signals from the antenna system and then down-converts the receivedsignals to IF signals. After amplification, analog-to-digital conversion, digital down-conversion, matched filtering, automatic gain control (AGC), the IF signals are sent to theBBU for further processing.

l Performs power control.
