摘要 |
<p>A switching network comprises a matrix of cross-point switches disposed in a pattern at selected ones of the cross-points in an array of mutually othogonal inlets and outlets. The pattern of selected cross-points is built up from a rectangular array of basic layouts each comprising eight cross-point switches distributed among the 16 cross-points which is formed by a group of four consecutive inlets crossing a row of four consecutive outlets. There are two types of basic layout: an A-type having its switches at the outer cross-points of its odd numbered lines and at the inner cross-points of its even numbered lines, and a B-type having its switches at the other cross-points. The basic layouts are disposed in a binary pattern over the matrix such that the matrix has a first line of alternating types of layout, a second line of alternating pairs of layout types etc.; each n-th line having its layouts in sets 2n-1 layouts of each type. This arrangement is particularly suitable for two-stage space-division concentrators using analog multiplexers to constitute lines of outlet switches.</p> |
