ZTE GPBX1 General Packet Processing Board

The ZTE GPBX1 is a high-performance General Packet Processing Board specifically designed for next-generation carrier-grade telecommunication platforms, including the ZXUR 9000 and ZXG10 iBSC systems. This module is built on the Advanced Telecommunications Computing Architecture (ATCA) and serves as a primary unit for intensive data processing and protocol handling in 2G/3G and converged SDR network environments. It is engineered to handle complex radio link control functions, including RLC and MAC layer processing, with enhanced throughput compared to previous generation processing boards.The GPBX1 facilitates the seamless transition of traffic between radio access networks and the core network by managing multiple interfaces such as Iub, Iu-CS, and Iu-PS. It incorporates advanced multicore processing technology to support high-density subscriber sessions and sophisticated resource management algorithms. The board's architecture is optimized for low-latency packet switching and high-speed data adaptation, ensuring stable performance during peak network loads.

Designed for high reliability, the GPBX1 supports full integration into the system's management framework, allowing for real-time monitoring and remote configuration. The front panel includes standardized LED indicators (RUN, ALM, ACT) for hardware status diagnostics and operational state identification. The board supports hot-swappable operation within the subrack, enabling maintenance or capacity expansion without disrupting the power supply to the entire chassis. It complies with international NEBS and ETSI standards for electromagnetic compatibility and thermal efficiency.
