PRELIMINARY
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
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.
Number of units: 0 – 1
Sound Hood
The sound hood attenuates noise from the climate unit, heat exchanger, and
air condition.
Number of units: 0 – 1
TMA-CM
One or two Tower-Mounted Amplifier Control Modules (TMA-CM) can be used
to provide ddTMAs with 15 V DC power through the bias injectors. It also
identifies ddTMA faults and forwards this information to the alarm module in the
RBS. If TMA-CMs are used, then they are installed in the DXU/PSU subrack.
Number of units: 0 – 2
TM
The Transport Module (TM) is a space in the cabinet reserved for transmission
equipment. The RBS is type-approved with transmission equipment from
Ericsson. Equipment from other manufacturers requires a new type approval
for the RBS. It is the responsibility of the owner/operator to obtain the type
approval. To ensure that the RBS function is not violated, the following is
recommended:
• Any transmission equipment installed in the TM must fulfil the requirements
in the Generic EMC standards IEC61000-6-3 and IEC61000-6-2
• All in/out interfaces (signal and power), which pass the cabinet border
between two different EMC zones, must be sufficiently EMC-protected
(transient protection, filtering)
• Shielded cables are recommended for connections between transmission
equipment and the cabinet connection field, and between transmission
equipment and the DXU or DXX.
