ABSTRACT:
A switching network for switching data in the form of cells transmitted in asynchronous transfer mode is of the "multiple path, cell auto-routing and directed sub-connection" type. Detectors are provided at each output port of the switching network to detect the absence of a missing cell in a call using that output. Incident registers store in response thereto an incident indication signifying that a cell is missing and indicating the path that the missing cell must have taken from path data derived from another cell of the same call.
