Hardware Units 6.1 Standard Hardware Units This section briefly describes the standard hardware units required for function, irrespective of configuration or frequency. ACCU A R Y The AC Connection Unit (ACCU) connects, disconnects, and distributes the incoming AC power supply to the PSUs and the climate unit. It consists of two parts: an ACCU Connection Unit (ACCU-CU) and an ACCU Distribution Unit (ACCU-DU). ACCU-02 is used in RBS 2106 and ACCU-05 is used in RBS 2106i and RBS 2106 V3.
RBS Product Description The CDU combines transmitted signals from several transceivers, and distributes the received signal to several transceivers. The CDU supports EDGE. Three CDU types are used in the RBS 2106 to support all configurations: • CDU-F is a filter combiner intended for high capacity solutions (baseband hopping only). Number of units: 1 – 3 CDU-G can be configured either for high capacity or for high coverage. It is a combiner that can be used for synthesizer or baseband hopping.
Hardware Units The DXU is provided with four connections for transmission interfaces. It can handle both 2,048 kbps (E1) and 1,544 kbps (T1) transmission interfaces. The DXU has hardware support for EDGE on 12 TRXs. DXU-21 is used in RBS 2106 and RBS 2106i. DXU-23 is used in RBS 2106 V3. Number of units: 1 A R Y dTRU The double Transceiver Unit (dTRU) contains two TRXs used to transmit and receive two radio carriers. It has a built-in combiner with the option to combine two TX signals into one TX output.
RBS Product Description 6.2 Optional Hardware Units This section describes the RBS 2106 optional hardware units. ASU A R Y 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.
Hardware Units DC Filter The DC filter is the interface between a +24 V DC external battery, and the IDM inside the RBS. The DC filter has the following main functions: ElectroMagnetic Compatibility (EMC) filtering • Connection of +24 V DC to the cabinet • Distribution of +24 V DC power to the IDM Number of units: 0 – 1 ddTMA A R Y • M Number of units per cabinet: 0 – 6 IN The ddTMA is to be mast-mounted and placed close to the antenna. It improves the receiver sensitivity.
RBS Product Description • Four spaces in the DXU/PSU subrack of the RBS 2106 and the RBS 2106i (RUs that are typically located in the OXU slots include the DXX and the TMA-CM) • One 19-inch OXU position is available between the CXU and the CDU subrack (used for HCU and ASU in co-sited cabinets) Smoke Detector A R Y The smoke detector is an optical device. Its purpose is to detect visual smoke. When smoke enters the detector, a light beam is deflected towards a photocell and an alarm is activated.
