Cisco 2800 Series

Cisco is redefining best-in-class enterprise and small- to medium-sized 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, Cisco 2800 Series integrated services
routers 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.
Benefits and Advantages
Enhanced Architecture
The Cisco 2800 Series features support for new
interface cards. Depending on the router model,
this can include up to four high-speed WAN
interface card (HWIC) slots, up to one Enhanced
Network Module (NME) slot, and up to one
Extension Voice Module (EVM) slot. Embedded
on the motherboard of the router is a hardware-
based VPN accelerator, up to three PVDM (Packet
Voice DSP Module) slots for integrated digital
signal processor (DSP) modules, two advanced
integration module (AIM) slots, up to two USB 1. 1
ports, and two Fast Ethernet 10/100 ports (Cisco
2801, 2811) or two Gigabit Ethernet 10/100/1000
ports (Cisco 2821, 2851). Additionally, optional
support for inline power (including 802.3af) is
offered.
Investment Protection and Versatility
The Cisco 2800 Series provides significant
additional value compared to prior generations of
Cisco routers such as the Cisco 1700 and 2600
Series routers at similar price points by offering
up to a five-fold performance improvement,
up to a ten-fold 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 Series and Cisco 2600
Series.
Integrated Switching
With support of up to 64 ports of integrated
switching with inline power, the Cisco 2800 Series
offers an excellent platform for combining two of
the most common components of any network
infrastructure. Additionally, with support for the
802.3af (Power over Ethernet [PoE]) standard, the
4- and 9-port Cisco EtherSwitch HWICs and the
16-, 24-, and 48-port EtherSwitch Service Modules
can provide power to any 802.3af-compliant
devices, greatly expanding the number and types
of devices that can be powered from the router's
integrated switch ports. An optional upgrade to
the internal power supply provides power to the
integrated switch ports.
Integrated Services
With the optional integration of numerous 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 Unity™ Express Voice Mail Module, Cisco
Intrusion Prevention Module, and Cisco Wide Area
Application Services 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 maintaining the benefits of
integration.
