ABSTRACT:
A Digital Subscriber Line Access Multiplexer (DSLAM) includes a Digital Subscriber Line interface unit for processing Physical Layer and Data Link Layer of the Digital Subscriber Line (DSL); at least two virtual DSLAM units adapted to simulate DSLAM to process a packet from the DSL interface unit; and a backhaul interface unit adapted to receive a packet processed by the DSLAM unit, and to send a packet from an access edge node or carrier equipment to the virtual DSLAM unit for processing. The disclosure further provides an Optical Network Unit, an Optical Line Terminal and a Base Station.
