The various configurations available for cabinets are described using the
following system:
In the example above, the cabinet is fitted with three CDUs, each
connected to two TRXs; the total number of TRXs is thus six in this
case. The CDU is type CDU-F.
The RF cables between each CDU and its associated dTRUs are
standardized and do not normally change. Each CDU uses a set of
standard RF wiring patterns for connection between each CDU and the
cabinet connection field.
In the figures and tables in the sections that follow, the cabinets shown
are fully-equipped. Configurations consisting of a part of the fully-
equipped cabinet can also be derived from the following figures and
tables.
