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.
Figure 1. Cisco 2800 Series
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.

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. Using the voice and fax modules, the Cisco
2800 Series can be deployed for applications ranging from voice-over-IP (VoIP) and voice-over-Frame Relay (VoFR) transport to robust,
centralized solutions using the Cisco Survivable Remote Site Telephony (SRST) solution or distributed call processing using Cisco Call
Manager Express (CME). The architecture is highly scalable with the ability to support up to 12 T1/E1s trunks, 52 foreign-exchange-station
(FXS) ports, or 36 foreign-exchange-office (FXO) ports concurrent with data routing and other services.

Feature
Benefit
Optional support for Cisco in-line power distribution to Ethernet switch network modules and HWICs can be used to
power Cisco IP phones.
Extension Voice Module Slots, available only on the Cisco 2821 and Cisco 2851, provide support for the Cisco
High-Density Analog and Digital Extension Module for Voice and Fax, providing support for up to 24 total voice and
fax sessions without consuming a Network Module Slot.
DSP (PVDM2) modules deliver support for analog and digital voice, conferencing, transcoding, and secure Real-
Time Transport Protocol (RTP) applications.
Cisco CME is an optional solution embedded in Cisco IOS Software that provides call processing for Cisco IP
phones. Cisco CME delivers telephony features similar to those that are commonly used by business users to meet
the requirements of the small to medium-sized offices.
Support for up to a 100 mailboxes using the Cisco Unity® Express voice messaging system is possible with the
integration of an optional voice-mail AIM or network module.
Interfaces for local telephone, private branch exchange (PBX), and gateway connections include FXS; FXO; direct
inward dialing (DID); ear and mouth (E&M); Centralized Automated Message Accounting (CAMA); ISDN Basic Rate
Interface (BRI); and T1, E1, and J1 with ISDN Primary Rate Interface (PRI); QSIG; and several additional channel-
associated-signaling (CAS) signaling schemes.
Branch offices can take advantage of centralized call control while cost-effectively providing local branch backup
using SRST redundancy for IP telephony.
Cost of Ownership and Ease of Use—Features and Benefits
The Cisco 2800 Series continues the heritage of offering versatility, integration, and power to branch offices. The Cisco 2800 Series offers many
enhancements to help enable the support of multiple services in the branch office as shown in Table 5.
Table 5. Cost of Ownership and Ease of Use—Feature and Benefits
Feature
Integrated channel service unit/data
service unit (CSU/DSU), add/drop
multiplexers, firewall, modem,
compression, and encryption
Optional network analysis module
Cisco IOS Software Warm Reboot
Benefit
Consolidates typical communications equipment found in branch-office wiring closets into a single,
compact unit; this space-saving solution provides better manageability
Provides application-level visibility into network traffic for troubleshooting, performance monitoring,
capacity planning, and managing network-based services (Note: Cisco 2811, 2821, and 2851 only)
Reduces system boot time, and decreases downtime caused by Cisco IOS Software reboots (Note:
Cisco 2801 will support the Cisco IOS Software Warm Reboot at a later point in time)
