ABSTRACT:
A crossconnect system utilizes a computer accessed matrix of crosspoints formed by a set of parallel conductors oriented perpendicular to a second set of parallel conductors with the sets lying in parallel planes. The crosspoints form open contacts which can be closed by stepper motor driven spring contacts to connect selected conductors from one set with selected conductors from the other set. A microprocessor system drives the stepper motor and implements movement of the spring contacts to the selected crosspoints.
