Abstract:
A telephone switch-integrated modem pool and broadband access concentrator providing PSTN access for dial-up data communication traffic, comprising:a switch terminating at least one local subscriber loop arranged for connection to a subscriber's data processing and communication equipment (subscriber equipment); a modem pool associated with said switch, said modem pool including at least one modem adapted to communicate with said subscriber equipment and to modulate/demodulate data packets sent to and received from said subscriber equipment; a broadband access concentrator for encapsulating/unencapsulating said data packets into/from a delivery format suitable for broadband transmission in a broadband data network, said broadband access concentrator including a broadband interface; a broadband data network pipe (broadband pipe) for connecting said broadband interface to at least one data network service provider data processing and communication system (service provider system); and processing means associated with said broadband access concentrator for providing LCP (link layer) management and translation between a first communication link extending between said modem pool and said subscriber equipment over said local loop and a second communication link extending between said modem pool and said service provider system over said broadband pipe, said processing means providing said LCP management and translation functions transparently on data traffic passing therethrough so that a point-to-point connection providing PAP/CHAP, NCP and other high level protocol service negotiation can be setup and maintained between said subscriber equipment and said service provider.
