ABSTRACT:
Equal access IP transport and Internet services are provided using a public switched telephone serving a plurality of defined geographic areas (LATAs). A switched multimegabit data service (SMDS) network and a frame relay network spans the geographic areas. A plurality of Internet service providers (ISPs) are connected to the SMDS network. A data hub node, connected to both the SMDS network and the frame relay network in each geographic area, includes a gateway router connected via a packet switch and at least one network access server to one of the central office switching systems. A central maintenance center monitors and maintains the wide area communications network through the SMDS and frame relay networks and data hub nodes. An ISP may setup conditions for redirection of all or a portion of a load to one or more network access servers in the hub for routing over the SMDS network in the event of overload.
