A wireless communication system comprises a hub; a plurality of radio access nodes, wherein each of the plurality of radio access nodes is coupled to the hub via a respective communication link. The hub comprises a plurality of forward devices that produce digitized versions of downstream analog radio frequency signals received from a plurality service provider interfaces; a plurality of reverse devices that produce reconstructed versions of upstream analog radio frequency signals for transmission to the plurality of service provider interfaces based on digitized version of the upstream analog radio frequency signals received from the plurality of radio access nodes; a plurality of transport interfaces to couple the hub to the plurality of communication links; and a switch having a plurality of ports communicatively coupled to the hub forward devices, the hub reverse devices, and the transport interfaces, wherein the switch selectively routes the digitized versions of the downstream analog radio frequency signals and the digitized versions of the upstream analog radio frequency signals among the plurality of ports. The plurality of ports comprises a plurality of input ports and plurality of output ports; wherein 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 at least one of the plurality of input ports. The switch transmits a port identifier over at least one of the plurality of output ports and, thereafter, searches a shared data structure to determine if a device is communicatively coupled to the at least one of the plurality of output ports.
