Two-stage crossbar distributor and method for operation

摘要

An apparatus provides signal links of M with N signal connections. A first stage has first switching matrices, wherein the first switching matrices are designed to establish at least one switchable signal link between each associated first signal connection and an associated second signal connection. A second stage has a second switching matrix with a size of N×M. In a sub-area of the second switching matrix the intersection points X2_p,q that comprise switching elements are precise those that for N≧M satisfy the conditions: p−Σ_λ=1ⁱ⁻¹n_λ≡q (mod n_i); 1≦p−Σ_λ=1ⁱ⁻¹n_λ≦n_i and 1≦q≦M.
