Abstract
Prior Art/Technical Problem: During the establishment of a call through a switching network 20, the path is selected on the basis of the instantaneous loading of the switching network and maintained during the call. The problem of eliminating local blocking by rearranging existing connections has not been satisfactorily solved because of errors occurring during the rearranging process. Basic Idea: Provide in an ATM exchange operating with virtual connections the same devices which assure the correct order of the cells in the 'connectionless' mode. Solution: Each output of the switching network is followed by an output unit 30 which ensures that the cells are output in the correct order. Advantage(s): Virtual connections can be adapted to the instantaneous loading of the switching network error-free at any time. The assurance of the correct order can be implemented so as to largely compensate for delay jitter.
