Abstract
For the establishment of vertual connections passing through switching matrices of a multi-stage switching system, it is provided that upon the arrival of a call packet requesting the establishment of a virtual connection, a central control device identifies all the switching matrices involved in the connection to be established and determines setup information that must be assigned to each of them in order to establish the connection. This setup information is fed to the individual switching matrices from the central control device in a setup packet along the path of the virtual connection to be established.
