The present invention is a method to protect a cross-connect OXC/OEXC used to forward at least one signal AB from a main input IN to a main output OUT. Said method comprises the following step: Dividing the at least one signal AB into two substantially identical signal parts, a first signal part A and a corresponding signal part B. Routing the at least one first signal part A through a first cross-connect OXC1/OEXC1, from the input IN to the output OUT. Detection of a failure affecting the at least one first signal part A. Interruption of the routing path for the at least one first signal part A. Routing the at least one corresponding signal part B through a second cross-connect OXC2/OEXC2, from the input IN to the output (OUT). <IMAGE> |
