Prior art redundancy of a network for information transmission is that individual components such as, for example, lines, switching networks, control computers are doubled. However, this has disadvantages particularly in view of economic feasibility. In order to be able to utilize simple, non-redundantly fashioned components, a redundant logically identical node is used (SN1',SN2',SN3') in addition to each node (SN1,SN2,SN3). Also each trunk (L1,L2,L3) between the nodes is supplemented with a redundant trunk (L1',L2',L3') potentially conducted via a different physical path. Both trunks are linked via at least one combiner/splitter element.
