摘要： A telecommunications switch has a matrix architecture of n × m bus-interconnected (33,34), or space-switch interconnected (74), switch nodes (30) together with additional switch nodes (30) and n × m switch peripherals (50) connected to the switch nodes externally of the bus (space-switch) interconnected switch node matrix. Fault protection redundancy is provided by providing each one of the peripherals with connections to two different switch nodes only one of which is enabled at any one time.
