RBS 2107 1 Product Overview The RBS 2107 is a medium-capacity base station. It is used for outdoor applications, with up to three double TRansceiver Units (dTRU). There is space inside the cabinet for transmission equipment and battery backup. The RBS 2107 is designed to be transported as a fully assembled cabinet, with the exception of batteries, to the site. All units in the cabinet are easily accessible from the front of the cabinet, which means it can be positioned against a wall. 1.

RBS 2107 Surface and Colour The RBS 2107 has a surface quality according to Ericsson standard class A3/B6. Table 2 3 RBS 2107 Colours Colour Reference Number Ericsson Number Grey RAL 7035 MZY 509 01/8119 Space Requirements Installation and maintenance require that the door can be opened at least 90 . In practice this means that the space in front of the cabinet must be kept clear for a distance of 1000 mm, see figure below. No free space is needed at the back of the cabinet.
RBS 2107 Footprint The footprint of the RBS 2107 is 1000 mm wide and 710 mm deep. Note that the door, which protudes 216 mm, is not included in the footprint because its lower edge is clear of the ground.

RBS 2107 Figure 6 5.1 RBS 2107 Overview Standard Hardware Units This section briefly describes the standard hardware units required, irrespective of configuration or frequency. ACCU-32 The AC Connection Unit (ACCU) connects, disconnects, and distributes the incoming AC power supply to the PSUs and the climate unit. Number of units: 1 BFU-21 The Battery Fuse Unit (BFU-21) supervises the connection or disconnection of the batteries.
RBS 2107 refrigerating capacity; so the cabinet cannot be cooled to a temperature lower than the outside (ambient) temperature. Number of units: 1 CDU-J The Combining and Distribution Unit (CDU-J) is the interface between the transceivers and the antenna system. All signals are filtered before transmission and after reception by means of bandpass filters. The CDU-J allows several dTRUs to share antennas.
RBS 2107 FCU The Fan Control Unit (FCU) controls the fans in the cooling system by regulating fan speed. The FCU is controlled by the DXU. Number of units: 1 IDM The Internal Distribution Module (IDM) is a panel for distributing the internal +24 V DC power to the various units. Each distribution circuit in the cabinet is connected to a circuit breaker in the IDM. Number of units: 1 PSU The PSU converts 120 – 250 V to regulated +24 V DC.
RBS 2107 Number of units: 0 – 6 DC/DC Converter The DC/DC converter can supply −48 V DC power to transmission equipment in the TM compartment. It converts +24 V DC to -48 V DC. Number of units: 0 – 2 DC Filter The DC filter is the interface between a +24 V DC external power source, such as a battery, and the IDM inside the RBS.
RBS 2107 ESB TG synchronisation is the technology used to expand one RBS 2107 cabinet with another RBS cabinet in the same cell. The ESB is the cable between the DXUs. Number of units: 0 – 1 Gas Collecting Kit The batteries can be fitted with a gas evaporating kit, which removes gases from the cabinet. Number of units: 0 – 1 OXU The following Optional Expansion Unit (OXU) positions are available: • Two spaces in the DXU/dTRU subrack 1 × 5 TE and 1 × 12 TE (× 5.
RBS 2107 RX-Splitter 01 RX-Splitter 01 distributes the receiver signals from the CDUs to the dTRU in specific configurations of the RBS. Number of units per cabinet: 0 – 1 6 Interfaces This section lists all external connectors, as well as the test interface and the operator interface. Internal connections, the test interface, and the operator interface are located in some cabinet hardware units. 6.1 External Connections All external connectors enter through the bottom of the cabinet.
