Introduction

This sample configuration shows two Cisco 827 Digital Subscriber Line (DSL) Routers connecting to a Cisco 6130 NI-2 Digital Subscriber Line Access Multiplexer (DSLAM) and terminating on a Cisco 6400 Universal Access Concentrator (UAC). The Cisco 6400 has two node route processor (NRP) adapters installed. Each NRP terminates a single 827 DSL router.

An end-to-end configuration is provided in the "Configurations" section.
