4.9.1 Functions of the DFCBThis describes the functions of the DFCB. The DFCB is used with the DFCU to combine fiveor six carrier signals for transmission.

The functions performed by the DFCB are as follows:

l The DFCB tunes the one or two carrier signals from the DTRU and combines the signalsinto one before transmitting the signal to the DFCU. In the DFCU, the incoming signalfrom the DFCB is combined with other four carrier signals, and then is transmitted to theantenna after filtering and amplification.

l Detects the VSWR alarms of the antenna system and provides the function of the VSWRalarms whose thresholds are adjustable

l The DFCB (900 MHz) transmits the incoming signals from the antenna to the duplexer andLNA, divides the signals, and then transmits the signals to the DTRU. The DFCB alsocontrols the signal gain of the amplifier.

NOTEYou are not advised to use the antenna ports of the DFCB (900 MHz) except in special situations.

The following lists an example when the antenna ports of the DFCB are used.

l The configuration of six TRXs within a cell is achieved through the cascading of a DFCUand a DFCB. To expand the capacity of the cell without adding additional RF front-endmodules (for example, seven or eight TRXs), the antenna ports of the DFCB (900 MHz)can be used to transmit one or two carrier signals.

l The DBRU is the main functional module of the DTRU. It provides modulation/

demodulation, data processing, and combining/dividing between the baseband signals andRF signals.

l The DTPS is the power supply board of the DTRU. The DTPS converts the –48 V DCpower into +28 V DC power for the DPAU. The DTPS also supplies three routes of powerrequired by the TRX: 8 V, 4 V, and 3.3 V.

l The DPAU performs the following functions:– Amplifies the signals transmitted from the DBRU to the required power level

– Couples the output power for a loopback test and the power detection

– Provides the detected temperature of the power amplifier

– Provides wideband combination and PBT functions

Functional modes of the DTRUl RF Transmit Mode

– In the transmit independency mode, the two TRXs work independently without usingthe combination unit. Figure 4-35 shows the working principle in the DTRU transmitindependency mode.

Figure 4-35 Transmit independency mode

– In the PBT mode, only one TRX in the DTRU is used. One route of signals goes through

modulation and DA conversion. Then, the converted RF signals are divided into tworoutes and sent to the power amplified for amplification. At last, the amplified signalsare combined. As these two routes of signals are aligned in phase, the output power isamplified after combination. Figure 4-36 shows the working principle in the DTRUPBT mode.

Figure 4-39 Receive independency mode

– In the receive diversity mode, each main/diversity signal is divided into two routes

through a divider, and then sent to the main/diversity port of the two TRXs. Note onlytwo channels of RF signals are routed into the DTRU through the RF cables. Figure4-40 shows the working principle in the DTRU receive diversity mode.

Figure 4-40 Receive diversity mode

– In the 4-way receive diversity mode, four routes of signals are sent to one TRX. The 4-

way receive diversity helps achieve more uplink gain than the main receive diversitydoes. Note in the 4-way receive diversity mode, only one TRX can be used in the DTRU.Figure 4-41 shows the working principles in the DTRU 4-way receive diversity mode.

NOTE

In inter-cabinet cell configuration, the RF RX cables should be connected between two cabinets. TheBTS3012 cabinet uses two RF RX cables with 2.8 m in length to set up the connection between the twocabinets. The RF RX cable uses SMA coaxial connectors at both ends.

If the DCOM is used in the DAFU subrack, two RF TX signals are required between the DTRU and theDDPU. For details on the connection of the ports, refer to Ports on the DCOM.

5.6.2 Indoor 1/2-Inch Jumper of the BTS3012This describes the function, appearance, pin assignment, and installation positions of the indoor1/2-inch jumper.
