Abstract: In a PCM switching network, a signal routing device is disclosed for diverting signals from a faulty section of the network to an emergency section. All the transmission paths included between the emergency section and the faulty section are shifted by one step towards the emergency section. At the outputs the reverse shift is performed.

Abstract: A system is shown for switching PCM signals from a normal transmission path to an emergency transmission path when a normal path fails. Transmission is suspended during a period equal to at least the longest transmission time to prevent the transmission of incomplete data or check signals over the emergency path. After the time period elapses, transmission is maintained over the emergency path.
