The dual SVC system of the present invention for an ATM device, an ATM switching device, or an ATM concentrator, has an active switch system and a standby switch system, for connecting ATM members through the SVC (switched virtual connection) and routing ATM information. A device for sending SVC information from the active switch system to the standby switch system in a real-time manner is provided. When switching from the active system to the standby system occurs, the transfer of the ATM information through the SVC is maintained without any interruption. The SVC connection information is sent from the active switch to the standby switch at the time of establishment or termination of a call in the active switch system.
