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, 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.
Figure 1. Cisco 2800 Series
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.
