Abstract

A processor and switching network includes two groups of terminals. Two CPU's are provided, one of which is active while the second is in standby mode. Each has an associated bus operating to transmit addresses and CCIS data, and to receive CCIS data. Two bus junctions are connected to the two CPU's via their buses in order to connect the first CPU to the second bus and vice versa. Bux extensions allow transfer of data between the active CPU and the two groups of terminals. Multiplexers link the active CPU to the terminal groups.
