Abstract
A method for extending the switching matrix of a communication system without interruption which is effected by reserving space for the routing addresses of the largest extension stage both in the header translation table of the interface devices and in the cell header of each ATM cell, and by providing a system split which is used to replace the old switching matrix assemblies with new switching matrix assemblies in steps, the paths via the new switching matrix assemblies, insofar as they lead to the same output-side interface devices as via the old switching matrix assemblies, being addressable using the same routing addresses.
