Abstract
A wireless communication system comprises a hub; a plurality of radio access nodes; a plurality of forward devices that produce digitized versions of downstream analog radio frequency signals; a plurality of reverse devices that produce reconstructed versions of upstream analog radio frequency signals; a plurality of transport interfaces to couple the hub to the plurality of communication links; and a switch having a plurality of ports. The plurality of ports comprises a plurality of input ports and plurality of output ports. The switch listens for a device identifier on at least one of the plurality of input ports to determine if a device is communicatively coupled to the input port. The switch transmits a port identifier over at least one of the plurality of output ports and searches a shared data structure to determine if a device is communicatively coupled to the output port.
