Distributed packet switching arrangement

摘要: An integrated packet switching and circuit comprising a number of modules (1000) each connected to corresponding plurality user terminals (1002). Each module includes time-slot interchange unit (1011) for providing circuit-switched communication channels control (1017) that controls the operation unit. also (1400) used both provide packet-switched among module, switch information between establish calls calls. A time-multiplexed (10) interconnects different modules.
