Definition
A digital subscriber line access multiplexer (DSLAM) delivers exceptionally high-speed data transmission over existing copper telephone lines. A DSLAM separates the voice-frequency signals from the high-speed data traffic and controls and routes digital subscriber line (xDSL) traffic between the subscriber's end-user equipment (router, modem, or network interface card [NIC]) and the network service provider's network.

Overview
This tutorial will examine strategies for improving upon and maximizing the benefits of DSL technology deployment and identifying those products and services that best increase carrier revenue yield.
