The Cisco 3800 Series routers offer the award-winning Cisco IP Telephony solution for wired and cordless WLAN phones, with Cisco CallManager
Express (CME), as an optional feature set embedded within Cisco IOS
®
Software. This solution is ideal for customers who want to decrease costs
and complexity by converging voice and data networks. By adding a Cisco Unity
™
Express advanced integration module (AIM) or network module
to this solution, small offices and branch offices can take advantage of a complete, all-in-one data, voice-processing, voice-mail, and auto-attendant
system. For larger, centralized IP Communications deployments, customers can deploy Survivable Remote Site Telephony (SRST) in their
Cisco 3800 Series routers with a central Cisco CallManager for highly scalable, highly available enterprise IP Communications. SRST is
an important component of the Cisco end-to-end IP telephony offering, providing feature-rich call-processing redundancy, while taking advantage
of the existing infrastructure at the branch office.
Cisco 3800 Series routers also feature the widest range of voice-gateway interfaces, scaling to meet the needs of the smallest to largest branch
requirements for voice termination densities using a combination of network modules, extension voice modules (EVMs), voice interface cards
(VICs), voice/WAN interface cards (VWICs), and onboard packet voice DSP modules (PVDMs). Customers have unprecedented scalability for
supporting up to 24 T1/E1 trunks and 88 foreign-exchange-station (FXS) ports for analog phones, fax machines, key systems, and conference
stations.
WIRELESS SERVICES
The Cisco 3800 Series can provide a complete wireless solution for branch offices, small/medium sized businesses, and Wi-Fi hotspots.
Wireless services enable greater mobility for employees, partners, and customers, resulting in increased productivity. The Cisco 3800 Series
supports an integrated access point for wireless LAN connectivity, Wi-Fi Hotspot services for public access, wireless infrastructure services for
cordless WLAN telephony and for larger sites, and land mobile radio over IP for radio users.
INTEGRATED SERVICES
Figure 2 also highlights the fact that with the unique integrated services architecture of the Cisco 3800 Series, customers can now securely deploy
IP Communications with traditional IP routing and still leave the network-module slots available for additional advanced services. With the optional
integration of a wide array of services modules, the Cisco 3800 offers the ability to easily integrate the functions of standalone network appliances
and components into the Cisco 3800 Series chassis itself. Many of these network modules, such as the Cisco Network Analysis, Cisco Intrusion
Detection System, and Cisco Content Engine network modules, have embedded processors and hard drives that allow them to run largely
independently of the router, while allowing their management from a single management interface. This flexibility greatly expands the potential
applications of the Cisco 3800 Series beyond traditional routing while still maintain the benefits of integration: ease of management, lower solution
costs, and increased speed of deployment.
PRIMARY FEATURES AND BENEFITS
The global economy is increasingly reliant on networked enterprise applications and the Internet as indispensable tools for tackling urgent business
challenges. Successful companies require secure, high-performance networks that can quickly adapt to support volatile business conditions, while
helping boost competitive advantage and increase network efficiencies. They must invest in network infrastructure that uses essential technologies
and easily enables improved models of communication without disruption to core business functions. The Cisco 3800 Series helps companies operate
securely in a networked economy and easily implement network services that will improve their business without impacting existing operations or
degrading network performance.
Table 1 gives the features and benefits of the Cisco 3800 Series.
