    摘要： A method is described for mapping a protection scheme over a switching system including a plurality of switching matrices, and including multiple inputs and multiple outputs connected to at least part of the plurality of switching matrices. The method includes the step of identifying an input protection group correlated to at least part of the multiple outputs, wherein the input protection group includes multiple working inputs out of the multiple inputs and includes at least one protection input out of the multiple inputs for protecting the multiple working inputs, the at least one protection input being connected to at least one of the plurality of switching matrices different from the switching matrix connected to one of the multiple working inputs, wherein the correlation indicates that the multiple working inputs are cross-connected to the at least part of the multiple outputs across the switching system, and wherein the at least part of the multiple outputs are connected to different switching matrices, includes the step of identifying a number of cross-connections required across the switching system from the multiple working inputs and the at least one protection input to the at least part of the multiple outputs in case of protecting the multiple working inputs with the at least one protection input, and includes the step of allocating the number of cross-connections over the switching system by crossing a single switching matrix out of the plurality of switching matrices.

    摘要： The invention relates to a remote interface device (12) for terminating a remote optical fiber link, with a network input (14), a network output (15), a customer input (17) and a customer output (16) for data signals, characterized in that the device (12) is designed such that during normal operation, only data received at the customer input (17) is sent onto the network output (15), that the device (12) is further designed such that in case of a failure at the network input (14) or a failure at the hardware of the remote interface device (12), the network output (15) is closed, i.e. no signal at all is sent onto the network output (15), and in case of a failure at the customer input (17), a dedicated auxiliary signal only is sent onto the network output (15). The inventive device allows the use of the full data transfer capacity for customer's data during normal operation, and allows distinction between different types (provider, customer related) of connection failures.
