CHAPTER 1
Introduction
1.1 Overview
This user’s guide explains how to configure the following ZyXEL devices:
• The P-974H model is a 4-port cable modem and router combined. It also has a
USB 2.0 port allowing computers without an Ethernet connection to join your
network.
• The P-974HW model adds IEEE 802.11g wireless capability allowing wireless
clients to join your network.
This user’s guide refers to these models simply as the “ZyXEL Device”. Please
refer to Appendix A on page 71 for a complete list of features for your model.
1.2 Internet Access Application
The ZyXEL Device is the ideal high-speed Internet access solution. It is compliant
with the DOCSIS 2.0 and Cable Home 1.1 standards. The ZyXEL Device allows you
to connect up to four computers to its 10/100 Mbps Ethernet ports and an
additional computer to its USB 2.0 port to form your local area network and
connect to the Internet. In addition, for P-974HW, wireless clients can access your
network resources and the Internet.
