Ericsson CPUB2-12QC

The Ericsson CPUB2-12QC (ROJ208864/2) is a high-performance CPU board designed for use within Ericsson Baseband Units (BBU) to support multi-standard mobile networks. Equipped with a 12-core processing architecture, this module delivers powerful computational performance required for managing radio resource control, protocol processing, and high-capacity user traffic. As a core element of the baseband platform, the CPUB2-12QC coordinates data flows between sector modules, interfaces with radio units through high-speed optical links, and ensures optimized scheduling and system responsiveness.

Engineered for continuous operation in demanding telecom environments, the board supports GSM, UMTS, LTE, and 5G NR technologies. It communicates through optical and electrical interfaces over the BBU system backplane, enabling efficient data exchange with other functional modules. The CPU board also supports advanced synchronization mechanisms such as IEEE 1588v2 and SyncE to maintain accurate timing within the radio network. Powered by a standard –48 V DC telecom system, the CPUB2-12QC provides reliable performance and scalability for modern high-capacity mobile networks.
