Product Overview and Deployment Guidelines
This chapter describes the features and benefits of the WRP400, describes
deployment scenarios, and offers guidelines to help you plan your network.
•“WRP400 Features and Benefits,” on page 5
•“Deployment Models,” on page 6
•“Local Area Network Guidelines,” on page 11
•“Special Requirements for Voice Deployments,” on page 12
•“WRP400 Maintenance Operations,” on page 15
•“Remote Provisioning,” on page 17
WRP400 Features and Benefits
With a variety of features, the WRP400 offers the benefits of five devices in one:
1. Router: The WRP400 is a broadband router with a robust security firewall to
protect your network.
2. Switch: The WRP400 includes a built-in, 4-port, full-duplex, 10/100 Ethernet
switch to connect computers, printers, and other equipment directly or to attach
additional hubs and switches. Advanced Quality of Service functionality
ensures that you can prioritize traffic for data, voice, and video applications.
3. Analog Telephone Adapter: The WRP400 includes a two-port Analog
Telephone Adapter (ATA) that allows you to connect your analog phones or fax
machines to your configured Internet telephone service. Two traditional phone
lines also can be connected for support of legacy phone numbers and fax
numbers.

4. Wireless Access Point: The WRP400 has an integrated 802.11b/g wireless
access point that secures your communications with WEP and WPA security
protocols. It is preconfigured to support two wireless networks: one for private
use by your business and one for guest use by customers, temporary
employees, and other visitors.
5. Mobile Broadband Router: When you attach a compatible Mobile Broadband
Modem to the USB port, the WRP400 allows multiple Wi-Fi devices to share a
mobile broadband connection. This feature also can be used to provide
continuous Internet service by providing automatic failover to the mobile
network when the primary Internet connection is unavailable. For the latest copy
of the USB Modem Compatibility List, visit the following URL:

WRP400 may be different from corresponding tasks on other Cisco Small Business
routers, switches, and ATAs. Administrators should refer to this guide for the proper
procedures for installation, configuration, and management of the WRP400.
