Product Overview

The integrated services routing architecture of the Cisco 3800 Series is designed to embed and integrate security and voice processing with advanced wired and wireless services for rapid deployment of new applications, including application layer functions, intelligent network services, and converged communications. The Cisco 3800 Series supports the bandwidth requirements for multiple Fast Ethernet interfaces per slot, time-division multiplexing (TDM) interconnections, and fully integrated power distribution to modules supporting 802.3af Power over Ethernet (PoE), while still supporting the existing portfolio of modular interfaces. This ensures continuing investment protection to accommodate network expansion or changes in technology as new services and applications are deployed. By integrating the functions of multiple separate devices into a single compact unit, the Cisco 3800 Series dramatically reduces the cost and complexity of managing remote networks.

The two models, the Cisco 3825 and the Cisco 3845, are available with three optional configurations for AC power, AC power with integrated inline power support, and DC power.

Secure Network Connectivity for Data, Voice, and Video

An important component of the Cisco Self-Defending Network, the Cisco 3800 Series features

the industry's most comprehensive security services embedded and integrated within the router, providing customers with a single, resilient platform to rapidly deploy secure networks and applications.

Cisco Integrated Services Routers provide advanced security services and management capabilities such as built-in hardware encryption acceleration, IPSec, VPN (Advanced Encryption Standard [AES], Triple Digital Encryption Standard [3DES], DES and Multiprotocol Label Switching [MPLS]), stateful firewall protection, dynamic intrusion prevention (Intrusion Prevention System [IPS]), and URL filtering support. Cisco IOS security feature sets enable all of these rich security features, as well as applications such as Network Admission Control (NAC), Dynamic Multipoint VPN (DMVPN), and Voice and Video Enabled VPN (V3PN).

For ease of management and configuration, the 3800 Series also features the intuitive, Web-based Cisco Router and Security Device Manager (SDM). For secure services management, every Cisco integrated services router supports Secure Shell Protocol Version 2 (SSHv2) and Simple Network Management Protocol Version 3 (SNMPv3) protocols to encrypt the management session.

Converged IP Communications

As shown in Figure 2, the Cisco 3800 Series meets the IP Communications needs of midsize to large enterprise branch offices, while delivering industry-leading security within a single routing platform. By embedding voice services inside the router, Cisco provides customers with maximum deployment flexibility, plus higher densities for stations, trunks, and conferencing.

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 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.
