What You Should Know
This guide is intended for data communications managers or telecommunications managers who are
installing, configuring, or maintaining voice network modules and interface cards. It assumes that
you already have a working IP LAN or WAN, or that you know how to set one up, and that you want
to add voice capability to it. It does not tell you how to design or install a LAN or WAN, assign IP
addresses, install routers and configure them for IP traffic, or perform other basic tasks. It also
assumes that you are familiar with Cisco IOS software, and that you know how to configure the
routers on your LAN or WAN for IP service.
For E&M installations, you should also be familiar with telephony concepts and PBX operation.
The “List of Terms” near the end of this guide provides a glossary of many terms and concepts used
by voice over IP. For further information on voice over IP features, refer to the Voice
Network Module and Voice Interface Card Configuration Note, the Voice over IP Software
Configuration Guide, your router installation and configuration guide, the Regulatory Compliance
and Safety Information document for your router, and the Cisco IOS configuration guides and
command references.
In this guide:
• Commands in the text are shown in boldface.
• Variables for which you supply values are in italics.
• Italics are also used for the titles of publications and for new words or concepts.
• Information the router displays on the console screen is in screen font.
• Information that you enter at the console keyboard is in boldface screen font.
Cisco documentation and additional literature are available in a CD-ROM package, which ships with
your product. The Documentation CD-ROM, a member of the Cisco Connection Family, is updated
monthly. Therefore, it might be more up to date than printed documentation. To order additional
copies of the Documentation CD-ROM, contact your local sales representative or call customer
service. The CD-ROM package is available as a single package or as an annual subscription.
You can also read Cisco documentation on the World Wide Web at http://www.cisco.com,
http://www-china.cisco.com, or http://www-europe.cisco.com. From here, you can submit
comments electronically. Click Feedback on the title bar, and then select Documentation. After you
complete the form, click Submit to send it to Cisco. We appreciate your comments.
If you have questions or need help, refer to the section “Cisco Connection Online” at the end of this
