Abstract
A redundant structure control device for an (N+1) reluctant structure exchange, capable dealing with line trouble and line interface device trouble. When line trouble is detected frame tag attaching is arranged so a frame coming from a interface device originally connected with a troubled line toward die troubled line may be sent to a spare line. When a troubled line interface device is detected, frame tag attaching is arranged so that a frame coming from a line originally connected with the troubled line interface device be sent to a spare line interface device and a frame earning from the spare line interface device may flow so the line originally connected with the troubled line interface device, and instructs the change of a cell tag coming from an ATM switch toward the troubled line interface device, to a value indicating that the cell be sent to the spare line interface device.
