CISCO 2800 SERIES INTEGRATED SERVICES ROUTERS
Cisco Systems®, Inc. is redefining 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, and video
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, and voice 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 new 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, new 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 connectivity requirements; and sufficient performance and slot density for future network expansion requirements and advanced
applications.

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. With the Cisco IOS® Software Advanced Security feature set, the Cisco 2800 provides a robust
array of common security features such as a Cisco IOS Software Firewall, intrusion prevention, IPsec VPN, Secure Shell (SSH) Protocol
Version 2.0, and Simple Network Management Protocol (SNMPv3) in one secure solution set. Additionally, by integrating security functions
directly into the router itself, Cisco can provide unique intelligent security solutions other security devices cannot, such as network admissions
control (NAC) for antivirus defense; Voice and Video Enabled VPN (V3PN) for quality-of-service (QoS) enforcement when combining voice,
video, and VPN; and Dynamic Multipoint VPN (DMVPN) and Easy VPN for enabling more scalable and manageable VPN networks. In
addition, Cisco offers a range of security acceleration hardware such as the intrusion-prevention network modules and advanced integration
modules (AIM) for encryption, making the Cisco 2800 Series the industry’s most robust and adaptable security solution available for branch
offices. As Figure 2 demonstrates, using a Cisco 2800 Series uniquely enables customers to deliver concurrent, mission-critical data, voice, and
video applications with integrated, end-to-end security at wire-speed performance.
CONVERGED IP COMMUNICATIONS
As shown in Figure 2, the Cisco 2800 Series can meet the IP Communications needs of small-to-medium sized business and enterprise branch
offices while concurrently delivering an industry-leading level of security within a single routing platform. Cisco CallManager Express (CME)
is an optional solution embedded in Cisco IOS Software that provides call processing for Cisco IP phones. This solution is for customers with
data-connectivity requirements interested in deploying a converged IP telephony solution for up to 72 IP phones and—as of Cisco IOS 12.3(11)
release—for up to 96 IP phones. With the Cisco 2800 Series, customers can securely deploy data, voice, and IP telephony on a single platform
for their small-to–medium sized branch offices, helping them to streamline their operations and lower their network costs. The Cisco 2800
Series with optional Cisco CME support offers a core set of phone features that customers require for their everyday business needs and takes
advantage of the wide array of voice capabilities that are embedded in the Cisco 2800 Series (as shown in Table 1) together with optional
features available in Cisco IOS Software to provide a robust IP telephony offering for the small to medium-sized branch-office environment.
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. With
the optional integration of a wide array of services modules, the Cisco 2800 Series offers the ability to easily integrate the functions of
standalone network appliances and components into the Cisco 2800 Series chassis itself. Many of these modules, such as the Cisco Network
Analysis Module, Cisco Voice Mail Module, Cisco Intrusion Detection Module, and Cisco Content Engine Module, have embedded processors
and hard drives that allow them to run largely independently of the router while allowing management from a single management interface. This
flexibility greatly expands the potential applications of the Cisco 2800 Series beyond traditional routing while still maintaining the benefits of
integration. These benefits include ease of management, lower solution costs (CAPEX and OPEX), and increased speed of deployment.
