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		● The Cisco 2900 Series enables deployment in high speed WAN environments with concurrent services
Integrated 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.

	Architectural Feature		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)		● Embedded hardware encryption acceleration is enhanced to provide higher scalability, which combined
	VPN Hardware Acceleration		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.
