BTS Frame Description
The BTS is the interface between the span lines to/from the Cellsite Base
Station Controller (CBSC) and the site antennas. This frame is described
in three sections:
The top interconnect plate where all connections are made.
The upper portion of the frame which houses circuit breakers, cooling
fans, and the C-CCP shelf.
The lower portion of the frame which houses the LPA fans, LPAs, and
TX filter/combiners.
The -48 V version of the BTS also has a section below the LPAs
containing a power conversion shelf that supplies power to the LPAs.
Use the illustrations that follow to visually identify the major
components, that make up the Motorola SC 4812T BTS frame.
Top Interconnect Plate (see Figure 1-6 or Figure 1-7)
