ABSTRACT

This document describes the procedures recommended to

automatically configure connections between B-NT Customer Premises

Equipment and Internet Services, focusing on the requirements across the

DSL local loop. It specifies the usage of PPP and its related control protocols

for services that require authentication, accounting and addressing and

DHCP for bridged configurations and extensions beyond the configuration

capabilities of a PPP connection.
