Abstract:
1. An access device for supporting a variable data layer, the access device comprising: a user access processing module unit having an analog/digital access processing unit and a local area network access processing unit; a central control processing module unit connected to the user access processing module unit and having: a wide area network access processing module unit connected to the user access processing module unit and the central control processing module unit, the wide area network access processing module unit having: a frame conversion processing unit comprising a framer/deframer for transmitting/receiving ATM cells from the central control processing module unit through a first bus, and forming and extracting xDSL frames; an encoder/decoder unit for converting the xDSL frame into a signal usable in an external xDSL network, or the signal from the external xDSL network; and a physical access unit for performing physical layer access interface, wherein the analog/digital access processing unit is connected to the frame conversion processing unit via the HPI bus.
