Introduction
1.1 Overview
The Device is an Ethernet integrated access device (IAD), which provides Voice over IP (VoIP)
communication capabilities to allow you to use a traditional analog telephone to make Internet
calls. By integrating all of these features, you are provided with ease of installation and high-speed,
shared Internet access. The Device is also a complete security solution with a robust firewall based
on Stateful Packet Inspection (SPI) technology and Denial of Service (DoS).
