Abstract

A digital subscriber line access network comprises a remote Ethernet device disposed in a serving area interface. The remote Ethernet device serves as an Ethernet bridge for a neighborhood service area. The remote Ethernet device communicates with a plurality of customer premises modems in the neighborhood service area using an Internet Protocol over an Ethernet standard with a digital subscriber line physical layer. An Ethernet switch disposed at a central office communicates with the remote Ethernet device via a fiber optic medium using an Internet Protocol over a second Ethernet standard. The Ethernet switch provides a packet data core network termination.
