Introduction

This sample configuration shows a Cisco 827 Digital Subscriber Line (DSL) Router that has been configured with AAL5MUX encapsulation and supports multiple Permanent Virtual Circuits (PVCs). The Cisco 827 is connected to a Cisco 6130 Digital Subscriber Line Access Multiplexer (DSLAM) and terminates at a Cisco 6400 Universal Access Concentrator-Node Route Processor (UAC-NRP). Also included are configurations for the Cisco 6130 and Cisco 6400.

In this example, IP is used for both PVCs to show how it maps to the Cisco 6400 UAC-NRP.
