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
The ddTMA is to be mast-mounted and placed close to the antenna. It improves
the receiver sensitivity. The ddTMA saves feeder cables by duplexing RX and
TX signals to the same cable.
Number of units per cabinet: 0 – 6
ESB
TG synchronization is the technology used to expand one RBS 2106 cabinet
with another RBS cabinet in the same cell. The External Synchronization Bus
(ESB) is the cable connected between the DXUs.
Number of units: 0 – 1
Gas Collecting Kit
The acid leads can be supplied with a gas evaporating kit, which evacuates
gases from the cabinet.
Number of units: 0 – 1
HCU
The HCU contains three hybrid combiners. Each hybrid combines two RF
signals, delivered from the dTRU, into one.
Number of units: 0 – 1
OXU (RBS 2106 and RBS 2106i only)
