Covad has an RDC in each area where it operates--for example, San Francisco Bay or New York City. Covad aggregates client traffic from each central office in a region on its regional network, switches the traffic through its RDC, and then delivers the traffic to the corporate network over one or more high-speed wide area network (WAN) circuits. The WAN circuit terminates on a corporate router or switch.
