About This Part
The Ericsson RNC Main Subrack (BFX90102/4R1A) serves as the fundamental chassis for a Radio Network Controller (RNC) within 3G UMTS mobile networks. The RNC is a critical element responsible for managing radio resources, controlling Node B base stations, and handling mobility functions for user equipment. This subrack provides the physical housing and backplane connectivity for various RNC processing units, interface cards, and power supply modules, forming the operational core of the RNC. Typical use cases include deployment in existing 3G networks requiring expansion, upgrades, or as a direct replacement for faulty units to ensure uninterrupted service. It's vital for maintaining the integrity and performance of the radio access network (RAN) by orchestrating communication between the core network and mobile devices. While specific technical specifications for the BFX90102/4R1A vary based on its configuration and generation, Ericsson RNC subracks are engineered for high availability and robust performance. They typically feature redundant power supply options, modular slot architecture for flexible card integration (e.g., control boards, transport boards, I/O modules), and robust environmental resilience. These subracks are designed to support a wide range of traffic capacities and subscriber loads, ensuring reliable operation in demanding telecom environments.
