Abstract
A telephone switch-integrated modem pool and broadband access concentrator provide improved data network access through a PSTN local loop. Rather than simply cascading data as TDM traffic through the PSTN, plural switch-integrated modems, a broadband access concentrator, and a broadband pipe are used to route data traffic between local loop subscribers and one or more data network service providers. Advantageously, point-to-point connections are maintained between subscriber and service provider equipment in order to enable continued use of high level subscriber-provider protocol service negotiation (such as PAP/CHAP, NCP and the like). LCP (link layer) management and translation between the asynchronous subscriber-modem pool link and the synchronous provider-modem pool link are handled transparently by the broadband access concentrator.
