Abstract:
1. A device, comprising: a plurality of ports adapted to convey traffic signals, wherein at least one of said plurality of ports is adapted to convey traffic signals and command signals; a switch network having a plurality of inverters, switches and conductive paths: the plurality of inverters, switches, and conductive paths arranged in a cascading configuration including at least two interconnected layers of the switches, each switch of the plurality of switches coupled to an inverter of the plurality of inverters, and each conductive path of the plurality of conductive paths assigned and coupled to a switch of said plurality of switches, each switch adapted to selectively couple ports to provide an electrically connected communication path for traffic signals between a pair of ports, wherein at least one port of said pair of ports is adapted to convey traffic signals and command signals; and a controller adapted to receive traffic signals and command signals from said at least one of said plurality of ports, and to decode said command signals and control said switches to provide said electrically connected communication path between said pair of ports in response to a decoded command signal, wherein a traffic signal is conveyed between said pair of ports via said controller.
