The Cisco 3900 Series offers superior performance and flexibility for flexible network deployments from small
business offices to large enterprise offices—all while providing industry-leading investment protection.
Key Business Benefits
The Cisco
®
ISR G2 routers provide superior services integration and agility. Designed for scalability, the modular
architecture of these platforms enables you to evolve and adapt with your growing business needs. Table 1 lists
the business benefits of the Cisco 3900 Series.
Table 1. Cisco 3900 Series Business Benefits
Benefits Description
Services integration
●
The Cisco 3900 Series routers offer increased levels of services integration with voice, video, security, mobility,
and data services.
●
The Cisco 3900 Series provides the highest performance and slot densities among the routers in the Cisco ISR
G2 portfolio, enabling you to maximize services integration and reducing overall capital expenditures (CapEx)
and operating expenses (OpEx).
Services on demand
●
A single Cisco IOS Software Universal image is installed on each Cisco ISR G2. The Universal image contains
all of the Cisco IOS Software technology sets, which you can activate with a software license. With the
Universal image your business can quickly deploy advanced features without downloading a new Cisco IOS
Software image. Additionally, larger default memory is included to support the new capabilities.
●
The Cisco SRE enables a new operational model that allows you to reduce CapEx and deploy a variety of
application services as needed on a single integrated compute services module.
High performance with
integrated services
●
The Cisco 3900 Series enables deployment in high-speed WAN environments with concurrent services
enabled up to 350 Mbps.
●
A multigigabit fabric (MGF) enables high-bandwidth module-to-module communication without compromising
router performance.
Network agility
●
Designed to address customer business requirements, the Cisco 3900 Series with the modular architecture
offers increased capacity and performance as your network needs grow.
●
The Cisco Services Performance Engine (SPE) modular motherboard enables upgrades to processing
capability in the future.
●
Dual integrated power supplies provide power redundancy; you can also configure them to provide additional
Cisco ePoE power to endpoints.
●
Modular interfaces offer increased bandwidth, a diversity of connection options, and network resiliency.
Energy efficiency
●
The Cisco 3900 Series architecture provides energy-savings features that include the following:
The Cisco 3900 Series offers intelligent power management and allows you 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 allows you to perform multiple functions, optimizing
consumption of raw materials 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 TCO—including materials and energy use.
High-efficiency power supplies and scalable power consumption are based on your network needs.
Investment protection
●
The Cisco 3900 Series maximizes investment protection by supporting:
Reuse of a broad array of existing modules supported on the original Cisco Integrated Services Routers to
provide a lower TCO
A rich set of Cisco IOS Software features carried forward from the original Cisco Integrated Services Routers
and delivered in a single universal image
●
The Cisco 3900 Series offers extensive growth possibilities as your network expands:
The SPE modular motherboard enables flexibility for future upgrades.
The highest scale for module density provides flexibility to add services as your business needs expand.
A 1-Gb default memory provides headroom to minimize field upgrades.
Platform Architecture and Modularity
The Cisco 3900 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
