Table 1. Key Business Benefits of the Cisco 2900 Series Integrated Services Routers
Benefits
Description
Services Integration
●
The Cisco 2900 Series ISRs offer increased levels of services integration with voice, video, security,
wireless, mobility, and data services, enabling greater efficiencies and cost savings.
Services On Demand
●
A single Cisco IOS
®
Software Universal image is installed on each ISR G2. The Universal image contains
all of the Cisco IOS technology sets which can be activated with a software license. This allows your
business to quickly deploy advanced features without downloading a new IOS image. Additionally, larger
default memory is included to support the new capabilities.
●
The Cisco Services Ready Engine (SRE) enables a new operational model which allows you to reduce
capital expenditures (CapEx) and deploy a variety of application services as needed on a single integrated
compute services module.
High Performance with
Integrated Services
●
The Cisco 2900 Series enables deployment in high speed WAN environments with concurrent services
enabled up to 75 Mbps.
●
A multigigabit fabric (MGF) enables high-bandwidth module-to-module communication without
compromising routing performance.
Network Agility
●
Designed to address customer business requirements, the Cisco 2900 Series modular architecture offers
increased capacity and performance as your network needs grow.
●
Modular interfaces offer increased bandwidth, a diversity of connection options, and network resiliency.
Energy Efficiency
●
The Cisco 2900 Series architecture provides energy-saving features that include the following:
◦ The Cisco 2900 Series offers intelligent power management and allows the customer to control power to
the modules based on the time of day. Cisco EnergyWise technology will be supported in the future.
◦ Services integration and modularity on a single platform performing multiple functions, optimizes raw
materials consumption and energy usage.
◦ Platform flexibility and ongoing development of both hardware and software capabilities lead to a longer
product lifecycle, lowering all aspects of the total cost of ownership, including materials and energy use.
◦ High efficiency power supplies are provided with each platform.
Investment Protection
●
The Cisco 2900 Series maximizes investment protection:
◦ Reuse of a broad array of existing modules supported on the original Integrated Services Routers
provides a lower cost of ownership.
◦ A rich set of Cisco IOS Software features carried forward from the original Integrated Services Routers
and delivered in a single universal image.
◦ Flexibility to adapt as your business needs evolve.
Platform Architecture and Modularity
The Cisco 2900 Series is architected to meet the application demands of today’s branch offices with design
flexibility for future applications. The modular architecture is designed to support increasing bandwidth
requirements, time-division multiplexing (TDM) interconnections, and fully integrated power distribution to modules
supporting 802.3af Power over Ethernet (PoE) and Cisco Enhanced PoE (ePoE). Table 2 lists the architectural
features and benefits of the Cisco 2900 Series.

Benefits
Modular Platform
●
The Cisco 2900 Series ISRs are highly modular platforms with several types of module slots to add
connectivity and services for varied branch-office network requirements.
●
The ISRs offer an industry-leading breadth of LAN and WAN connectivity options through modules to
accommodate field upgrades for future technologies without requiring a platform replacement.
Processors
●
The Cisco 2900 Series are powered by high-performance multi-core processors that can support the
growing demands of high-speed WAN connections to the branch-office while also running multiple
concurrent services.
Embedded IP Security (IPSec)
VPN Hardware Acceleration
●
Embedded hardware encryption acceleration is enhanced to provide higher scalability, which combined
with an optional Cisco IOS Security license, enables WAN link security and VPN services (IPSec
acceleration).
●
The onboard encryption hardware replaces and outperforms the advanced integration modules (AIMs) of
previous generations.
Multigigabit Fabric (MGF)
●
The Cisco 2900 Series introduces an innovative multigigabit fabric (MGF) that allows for efficient module-
to-module communication, enabling tighter services interactions across modules while reducing the
overhead on the route processor.
