<p>This invention concerns a telecommunications system having a plurality of user interface ports (interface port) connected to a switching matrix (data connection), with each user interface port being switchable between a working port (hot) and a protection port (stand-by) which can assume the function of the working port in the event of a failure of the latter, and where all the user interface ports are connected by a common wiring logic (back-plane system) to the user interfaces belonging to the respective ports. To increase security against false triggering of a switching operation in the switching means, switching means are provided at each user interface for switching between the working port and the protection port, are assigned together in groups controlled by a common higher-order controlling system (supervisor), with the higher-order controlling system (supervisor) being connected over a separate bidirectional data exchange connection to the rest of the telecommunications system, where there is information about the respective status (HOT/STAND-BY) of the connected user interface ports.</p> |
