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

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.
