Abstract:
In a switching center having input lines and output lines, a switching matrix for coupling the input lines and the output lines of the switching center to a network node in a communications network, the switching matrix comprising:primary switching elements each having an element input side;bus structures for respectively connecting one subset of input lines to said primary switching elements; andat least three assemblies each having a number of said primary switching elements and at least one output interface with an interface input side;said number of said primary switching elements supported by a common supporting element and connected on said element input side to said one subset of input lines by the same common bus structure;said interface input side connected to at least one of said primary switching elements of at least two of said assemblies connected to a different one of said one subset of input lines;said output interfaces respectively disposed at said assemblies between said number of said primary switching elements and a subset of output lines;each of said assemblies having one of said output interfaces connected on said interface input side to primary switching elements of at least two of said assemblies.
