To this end, the interface modules (23, 24) are divided into two groups, and each of the groups is assigned to a respective one of the switching matrices. A respective one of the switching matrices and a respective one of the groups of interface modules are arranged in, e.g., a cabinet or rack so as to form a unit, and the units are interconnected by simple internal links (34) such that both switching matrices (21, 22) are connected to all interface modules (23, 24).
