7 Basic Configurations with ddTMA
In the 900 MHz Frequency Band it is possible to implement a ddTMA and an
external Bias-T in RBS 2101, RBS 2102 and RBS 2202 for all configurations
except CDU-D configurations.
In the 1800/1900 MHz Frequency Band all configurations which support
ALNA/TMA, except CDU-D, can be equipped with external suplexers and
ddTMA in RBS 2101, RBS 2102 and RBS 2202. It is also possible to install
only the external duplexers without ddTMA. This shall not be seen as a new
configuration since the cabinet internal CDUs remain unchanged, but only
external radio equipment is added.
The configurations which support ddTMA are not presented in detail for all
cabinet variants or SCCs. This information can be found in the previous
sections Basic Configurations.
The figures below show examples of configurations which support ddTMA and
appropriate interface units for 900 MHz and 1800/1900MHz.
