High-Level View
The RAN consists of the main components shown in a high-level view in
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.
