Abstract

One embodiment of the disclosures made herein is a method for facilitating prescribed application functionality via a network element adapted for providing Digital Subscriber Line Access Multiplexing (DSLAM) functionality. In accordance with such a method, a first functionality server implements server-specific functionality whereby information associated with the server-specific functionality is generated. In response to implementing the server-specific functionality, information in a universal interface format is transmitted for reception by a first access server from a first functionality server. After receiving the information, the information is translated from the universal interface format to a system-compatible interface format.
