RBS Product Description
6.2 Optional Hardware Units
This section describes the RBS 2106 optional hardware units.
ASU
The Antenna Sharing Unit (ASU) is a part of co-siting, that is, using another
cabinet together with a GSM RBS 2106 cabinet in the same sector. The ASU
allows a TDMA (or other) cabinet and a GSM RBS 2106 cabinet to share RX
antennas.
Number of units: 0 – 1
ADM
The Auxiliary Distribution Module (ADM) handles distribution and fuse
connection of system voltage (+24 V DC and
0
48 V DC) to the Transport
Module (TM).
Number of units: 0 – 1
Battery Backup
Batteries can be installed inside the cabinet in either of the TM/BM spaces
located to the left of the BFU. An external source of battery supply can also be
used through the DC filter. if this is the case, then internal batteries can not
be used.
Note: The maximum distance between the RBS and the BBS must not
exceed 10 meters to prevent damage from, for example, lightning.
Bias injector
The bias injectors are used to provide the TMA with DC power from the
TMA-CM, over the RX/TX feeder cables. In the RBS 2106, the bias injector
is mounted between the antenna feeder and the CDU. In the RBS 2106i and
RBS 2106 V3, the bias injector is mounted between the antenna feeder and
the antenna connection field.
Number of units: 0 – 12
DC/DC Converter
The DC/DC converter can supply
0
48 V DC power to transmission equipment
in the TM compartment. It converts +24 V DC to
0
48 V DC.
Number of units: 0 – 2
