1.3High-Level View

The RAN consists of the main components shown in a high-level view in Figure 3. These components include:

•RAN Cabinet: exterior shell of the RAN containing cable connection points, ground studs, and slots or shelves supporting other RAN components.

•RAN Chassis: standard Compact PCI (cPCI) shelf capable of housing 21 industry standard cPCI circuit card modules. The modules are plugged into a common backplane providing data bussing between them.

•Related Electronics: including rectifiers, Power Amplifier Assemblies (PAAs), batteries, multiplexers, and a circuit breaker panel.

All components called out in the figure except for the multiplexers are separately installable in the field. In most cases, however, the RAN is shipped with a basic set of components having been ordered in advance by the customer and installed in the factory.
