AC connection unit and BFU
The ACCU handles the distribution and connection of the incoming power supply
voltages 200-250 VAC to the PSU´s and climate unit.
The BFU supervises and connects/disconnects the batteries at low voltage.
Transient and lightning protection
RBS 2106 is equipped with transient and lightning protection, located in the connection
boxes.
Climate Unit (CU) and FCU
The climate unit maintains the internal temperature in the cabinet. The CU communicates
with the DXU.
The fans are controlled by the DXU via the fan control unit with the aid of temperature
sensors placed inside the RU´s.
Tower Mounted Amplifier (TMA)
A Tower Mounted low noise Amplifier (TMA) is an option that can be used in order to
compensate for losses in the antenna feeder and to improve the overall receiver
performance. All the configurations, CDU-G or CDU-F are available with double duplex
TMA as option. Bias injectors and a TMA control module (TMA-CM) are needed in the
cabinet for TMA support. The BIAS injector is used to provide the TMA with DC power
from the TMA-CM over the RF feeders.
External Alarms
The customer may define up to 16 external alarms. The external device sets the alarm by
either an open or closed condition.
Antenna Sharing Unit (ASU)
The Antenna Sharing Unit (ASU) is a new unit that is available as an option for GSM 800
and GSM 1900. The ASU is intended to support antenna sharing between TDMA 850 and
GSM 800 or between TDMA 1900 and GSM 1900. The RX-path is fed from the Antennas
trough the feeders to the ARP (antenna reference point) of the RBS 2106. The signal is
then filtered and amplified in the CDU. From the RX output of the CDU the signal is fed
to the ASU where a small portion of the signal is fed to the RX input of the Co-Sited RBS.
