Abstract
The present invention provides a telecommunications packet switching system including a hardware portion and a software portion forming an advanced multiprocessing, multiprocessor system (including multiple processors, capable of running more than one process at a time). The hardware and software structures are fully distributed and fault-tolerant, providing a flexible configuration and remote management through the network itself, managing the switching and transmission of messages split into packets, including use of different specific protocols. The system can be connected to a variety of different networks, allowing a large concentration of low speed lines. A control station executes operational functions, and a terminal allows interaction with the system. A DC/DC converter is provided at each element in the processing unit.
