Abstract:
A method for switching transmission devices to an equivalent circuit for bidirectional transmission of ATM cells in an ATM network, the ATM network having at least two switching centers which each terminate a transmission section formed from a plurality of service links, comprising the steps of:feeding information in ATM cells to a respective receiving switching center of the two switching centers connected to the plurality of service links; providing monitoring devices, each of which are arranged at an end of a respective service link of the plurality of service links and by which a fault on the respective service link is determined; providing one standby link between the two switching centers; transmitting when a fault occurs on one of the service links, the ATM cells, which are transmitted on the service links, on said standby link in accordance with priority criteria and logic operation information contained in a cell header of the ATM cells, the ATM cells thereby being fed to further devices of the ATM network, a priority being assigned to the service links and to the standby link.
