BBU3900 and the DRFUs are installed in the indoor macro cabinet.

Figure 1-1 shows the BTS3900 system.

BTS3900cabinet

BBU

The BTS3900 mainly consists of the following components:

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

and the BSC.

l The DRFU is a double radio filter unit that processes two carriers. The DRFU performs

modulation and demodulation between baseband signals and RF signals, processes data,and combines and divides signals.

2 BTS3900 CabinetAbout This Chapter

The BTS3900 cabinet is designed in compliance with the IEC297 standard. It has a modular

structure and the baseband signals and RF signals are processed in it.

Based on the types of external power input, the BTS3900 cabinet is classified into the BTS3900

-48 V cabinet, the BTS3900 +24 V cabinet, and the BTS3900 220 V cabinet.

l The -48 V cabinet consists of the DRFU, BBU, GATM, DCDU-01, and FAN unit.

l The +24 V cabinet consists of the DRFU, BBU, DCDU-01, FAN unit, and power subrack

(DC/DC).

l The 220 V cabinet consists of the DRFU, BBU, DCDU-01, FAN unit, and power subrack

(AC/DC).

2.1 Appearance of the BTS3900 Cabinet

The BTS3900 cabinet is designed in compliance with the IEC297 standard. It is purple gray in

color and vertical in appearance.

2.2 Structure of the BTS3900 Cabinet

The BTS3900 cabinet supports three types of input power: -48 V DC, +24 V DC, and 220 V

AC. The cabinets that support different types of input power are different in structure, mainly

in power distribution unit.

2.2 Structure of the BTS3900 Cabinet

The BTS3900 cabinet supports three types of input power: -48 V DC, +24 V DC, and 220 V

AC. The cabinets that support different types of input power are different in structure, mainly

in power distribution unit.

2.2.1 Structure of the BTS3900 -48 V Cabinet

The BTS3900 -48 V cabinet uses the external -48 V DC input. The external -48 V DC power isdirectly led into the DCDU-01, which supplies the -48 V DC power to each component in the

cabinet. The BTS3900 -48 V cabinet can be installed alone or stacked with another BTS3900

-48 V cabinet.

2.2.2 Structure of the BTS3900 +24 V Cabinet

The BTS3900 +24 V cabinet uses the external +24 V DC input. The external input power is

converted into -48 V DC through the PSU, and then distributed to the internal components of

the cabinet through the DCDU-01. The BTS3900 +24 V cabinet can be installed alone or stacked

with a BTS3900 -48 V cabinet.

2.2.3 Structure of the BTS3900 220 V Cabinet

The BTS3900 220 V cabinet uses the external 220 V AC input power. The external input poweris converted into -48 V DC through the PSU, and then distributed to the internal components of
