摘要： A cross-connect device and method of operating the same is described having a plurality of N first transmission path input/output terminals and a plurality of M second transmission path input/output terminals, the device having a remotely actuated cross-connection arrangement. This arrangement includes at least three stages, each stage being implemented as a sparse crossbar: a first sparse cross-bar arrangement having first connection lines connected to the plurality of first transmission path input/output terminals and second connection lines connected to the plurality of second transmission path input/output terminals and a plurality of first switch elements for connecting selective ones of the first connection lines to selective ones of the second connection lines, a second sparse cross-bar arrangement having third connection lines connected to at least some of the first connection lines, and fourth connection lines and a plurality of second switch elements for connecting selective ones of the third connection lines to selective ones of the fourth connection lines, and at least a third sparse cross-bar arrangement having fifth connection lines connected to at least some of the fourth connection lines, and sixth connection lines and a plurality of third switch elements for connecting selective ones of the fifth connection lines to selective one of the sixth connection lines. The device has selectable connecting paths between the sixth connection lines and at least some of the second transmission path input/output terminals, whereby the total number of switching elements for the at least first to third sparse cross-bar arrangements is less than N x M.
