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 . 3 af) 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 . 3 af (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 . 3 af-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 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
