Abstract: A computer controlled signal router has a graphical user interface which pictorially represents the source channels and destination channels as intersecting, perpendicular sets of stripes with the intersections representing the switches of a cross-point switching matrix. Multiple signal channels are arranged in logical planes which may be displayed singly or in composite views. Links between source channels and destination channels which are effected by the cross-point switch are displayed by a visual indicator at the intersection of the selected source and destination stripes in the single plane view. In the multi-plane view, closed switches in their respective planes are represented by color coded segments of the visual indicator. Sources and destinations are linked and unlinked by selecting on the display the appropriate cross-point, or by designating a source and destination through selection of icons at the ends of the source and destination channel lines.
