Cisco 2800 Series Integrated Services Routers

Cisco Systems

, Inc. redefined best-in-class enterprise and small- to- midsize business routing with a new line of

integrated services routers that are optimized for the secure, wire-speed delivery of concurrent data, voice, video,

and wireless services. Founded on 20 years of leadership and innovation, the Cisco

2800 Series of integrated

services routers (refer to Figure 1) intelligently embed data, security, voice, and wireless services into a single,

resilient system for fast, scalable delivery of mission-critical business applications. The unique integrated systems

architecture of the Cisco 2800 Series delivers maximum business agility and investment protection.

Product Overview

The Cisco 2800 Series comprises four platforms (refer to Figure 1): the Cisco 2801, the Cisco 2811, the Cisco 2821,

and the Cisco 2851. The Cisco 2800 Series provides significant additional value compared to prior generations of

Cisco routers at similar price points by offering up to a fivefold performance improvement, up to a tenfold increase in

security and voice performance, embedded service options, and dramatically increased slot performance and

density while maintaining support for most of the more than 90 existing modules that are available today for the

Cisco 1700, Cisco 2600, and Cisco 3700 Series.

The Cisco 2800 Series features the ability to deliver multiple high-quality simultaneous services at wire speed up to

multiple T1/E1/xDSL connections. The routers offer embedded encryption acceleration and on the motherboard

voice digital-signal-processor (DSP) slots; intrusion prevention system (IPS) and firewall functions; optional

integrated call processing and voice mail support; high-density interfaces for a wide range of wired and wireless

connectivity requirements; and sufficient performance and slot density for future network expansion requirements

and advanced applications.

Data Sheet Secure Network Connectivity for Data, Voice, and Video Security has become a fundamental building block of any network. Routers play an important role in any network defense strategy because security needs to be embedded throughout the network. The Cisco 2800 Series features advanced, integrated, end-to-end security for the delivery of converged services and applications.
PAGE 3
Data Sheet Integrated Services Figure 2 also highlights the fact that with the unique integrated services architecture of the Cisco 2800 Series, customers can now securely deploy IP Communications with traditional IP routing while leaving interface and module slots available for additional advanced services.

Data Sheet Architecture-Features and Benefits The Cisco 2800 Series architecture has been designed specifically to meet the expanding requirements of enterprise branch offices and small-to-medium-sized businesses for today's and future applications. The Cisco 2800 Series provides the broadest range of connectivity options in the industry combined with leading-edge availability and reliability features.
PAGE 5
Data Sheet Modularity-Features and Benefits The Cisco 2800 Series provides significantly enhanced modular capabilities (refer to Table 2) while maintaining investment protection for customers. The modular architecture has been redesigned to support increasing bandwidth requirements, time-division multiplexing (TDM) interconnections, and fully integrated power distribution to modules supporting 802.3af PoE or Cisco in-line power, while still supporting most existing modules.
PAGE 6
Data Sheet Secure Networking-Feature and Benefits The Cisco 2800 Series features enhanced security functionality as shown in Table 3. Integrated on the motherboard of every Cisco 2800 Series router is hardware-based encryption acceleration that offloads the encryption processes to provide greater IPSec throughput with less overhead for the router CPU when compared with software-based solutions.
PAGE 7
Data Sheet IP Telephony Support-Features and Benefits The Cisco 2800 Series allows network managers to provide scalable analog and digital telephony without investing in a one-time solution (refer to Table 4 for more detail), allowing enterprises greater control of their converged telephony needs.
PAGE 8
Data Sheet Wireless Support-Features and Benefits The Cisco 2800 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. Table 5.
