Abstract
An automatic switching system and method is provided for switching between paths in a telecommunications switching system. A first circuit in each path receives substantially identical telecommunications signals containing telecommunications data and transmits substantially identical digital signals containing the telecommunications data. The first circuit is capable of detecting whether errors have occurred during transmission of the telecommunications signals, and of inserting into the digital signals an error indicator if a transmission error has been detected. At least one second circuit in each path accepts the digital signals from the first circuit in a selected path, and is capable of detecting whether the error indicator is present, and automatically switching to accept the digital signals from the first circuit in the non-selected path in response to detection of the error indicator.
