ABSTRACT:
An ATM switching system has at least one ATM multiplexer/demultiplexer located between central office lines of a subscriber side and an ATM switching network. In the ATM multiplexer/demultiplexer the n outputs of a switching element, whose m.multidot.n inputs are connected to m.multidot.n input lines of the subscriber side, are connected to n output lines at the side of the switching network. Respectively n inputs of m switching elements, whose respectively n outputs are connected to respectively n output lines of the subscriber side, are connected to n input lines at the side of the switching network. The respectively remaining (m-1).multidot.n inputs of these m switching elements are connected to the respectively n outputs of (m-1).multidot.m additional switching elements whose respectively m.multidot.n inputs are connected to the m.multidot.n input lines of the subscriber side.
