Abstract:
A method for proxy signaling in a digital subscriber line access multiplexer (DSLAM), the DSLAM providing a gateway between a public network and customer premises equipment for digital subscriber line communications, the method comprising:receiving an indication from a customer premises equipment that the customer premises equipment requires a switched virtual connection to a public network; recognizing that the customer premises equipment does not have signaling capability by referencing a list of customer premises equipment that does not have signaling capability; negotiating through a proxy signaling agent located on the DSLAM with the public network on behalf of the customer premises equipment using VPI/VCI addressing combinations from a signaling map stored by a network interface card, the network interface card communicatively coupled to the customer premises equipment; establishing a switched virtual connection between the DSLAM and the public network; and establishing a cross connect between the DSLAM and the customer premises equipment such that the customer premises equipment can communicate with the public network through the switched virtual connection using VPI/VCI addressing combinations from a communications map stored by the network interface card.
