CBU

CBU: A merge between SCB, GPB, TUB, and ETB

The CBU is the central control unit of the RBS. It executes the main part of the control functions in the RBS and controls the boards via the board processors.

Containing

• Power distribution to back plane

•Timing unit for network & radio synch with extended holdover time

• GPS interface for synch and positioning

• 4 x E1/T1/J1 ports

• Ethernet interface for site-LAN

• RS485 interface for control of fan and auxiliary equipment

• Main processor for RBS with 512Mbyte RAM and Flash disk

• IMA functionality

RUIF

RUIF: An interface board for 6 radio units

The RUIF is a device board unit used for communication between the Radio Units (RU) and the Baseband (BB) digital subrack. Communication includes control data, clock signals, and gamma data.

Containing

• Timing distribution to base-band boards and radio units

• Distribution of up- and down-link gamma signals between radio units and base-band boards

• Board processor for control of six radio units and six FSK-modems (Communication with ASC and RET)

RU21

RU21: A merge between MCPA and TRX

The RU receives digital data from the Baseband, converts the data into analog radio signals, amplifies these and feeds them to the FU. The RU also receives radio signals from the FU, converts these signals into digital data, and sends them to Baseband.

Containing

• Two transmitters and one DPD MCPA for two carriers DL

• Power clipping function

• One 2 branch diversity receiver for one carrier UL

• DC/DC converter for RU and FU with 10ms hold-up for logic parts

• One CPU (XP) for control of RU and filter unit (FU)

• Interface for FU control and power distribution to FU.

•Available with 20/30W per carrier.

FU12

FU12: A Filter and LNA unit for two antennas

The FU12 sits between the Radio Units (RU) and the antenna. It filters transmit and receive signals to and from the RU, and amplifies and controls the RX signal gain from the antenna to the RUs.

Containing

• One duplex filter for the first antenna (TX and RX)

• One receive filter for the second antenna (RX only)

• One TX port and four RX ports, two from each antenna

• Gain adjust for feeder compensation and gain select

• Power distribution to ASC and RET

• FSK modem for ASC and RET communication

• Parameter memory (EEprom)

• Control interface (I2C) from RU (Class 3 AU)
