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.
The DC filter has the following main functions:
• ElectroMagnetic Combatibility (EMC) filtering
• Connection of +24 V DC to the cabinet
• Distribution of +24 V DC power to the IDM
ddTMA
The ddTMA is to be mast-mounted and placed close to the antenna. It improves
the receiver sensitivity.
Number of units per cabinet: 0 – 6
OVP
The OVP module is a connection and overvoltage protection device for external
alarms, ESB, and PCM links. The OVP modules protect equipment inside
the RBS from overvoltages and overcurrents that can occur in external lines.
Examples of equipment requiring OVP include transmission lines, ESBs, and
external alarms. The OVP modules are mounted in the DF.
Number of units: 0 – 7
DXX
The DXX is a plug-in unit that combines cross-connect, control and interface
functions. It has four 2 Mbit/s interfaces complying with the G.703 standard. If
the DXX option is used, then it is located in the 12 TE (× 5.08 mm) Optional
Expansion Unit (OXU) position in the DXU/dTRU subrack.
Number of units: 0 – 1
