Introduction

This sample configuration shows a Cisco SOHO77 Digital Subscriber Line (DSL) Router that connects to a Cisco 6130 Digital Subscriber Line Access Multiplexer (DSLAM) and terminates on a Cisco 6400 Universal Access Concentrator (UAC). The Cisco SOHO77 is configured with PPP over ATM (PPPoA) with Network Address Translation (NAT) and IP address negotiation turned on. The Cisco SOHO77 also functions as a server for its local Ethernet clients.
