Cross-connect switch and method for providing test access thereto

摘要

The invention comprises an improved cross-connect switch constructed from a plurality of switch modules for connecting input lines to output lines. The improved switch includes a test access system in which selected input or output lines of the cross-connect switch are utilized as test ports. The switch utilizes computer algorithms to make connections between a test port and one of the switch modules through which a path connecting specified input and output lines passes to make a bridging connection to the path.
