Abstract
Equipment protection of a switch matrix (SM) in a network node, which contains a number of matrix modules (M-M, E-E) is achieved by slicing an input signal into k parallel signal slices (x()-x()) with k>2; coding the k signal slices into a number of n coded signal slices (x()-x()) with n>k+1 using an error correcting code to add redundancy to said input signal; switching said n coded signal slices through the switching matrix (SM) via n distinct matrix modules; and decoding the n coded signal slices into k decoded signal slices to correct errors introduced while passing through said switch matrix. Preferably, the switch matrix (SM) contains a first number of matrix boards (MB-MB, EB, EB), each carrying a second number of matrix modules (M-M, E-E). The n coded signal slices are switched via matrix modules on n distinct matrix boards.
