Cisco 2900 Series Integrated Services Routers (ISRs) are designed to

power the next phase of branch-office evolution, providing rich-media

collaboration and virtualization to the branch office while reducing

operating costs.

Cisco 2900 Series Integrated Services Routers build on 25 years of Cisco innovation and product leadership.

The Integrated Services Routers Generation 2 (ISR G2) platforms are protected for future generations with

multicore CPUs, support for high-capacity digital signal processors (DSPs) known as PVDM 3 for higher

density voice services plus basic video conferencing capabilities, high-powered service modules with

improved availability, Gigabit Ethernet switching with enhanced Power over Ethernet (ePoE), and new energy

monitoring and control capabilities while enhancing overall system performance.

Additionally, a new Cisco IOS Software Universal image and Services Ready Engine (SRE) module enable you

to decouple the deployment of hardware and software, providing a flexible technology foundation that can

quickly adapt to evolving network requirements. Overall, the Cisco 2900 Series offers unparalleled total-cost-

of-ownership (TCO) savings and network agility through the intelligent integration of market-leading security,

unified communications, wireless, and application services.

The routers include:

• Services on demand—The Cisco 2900 Series Integrated Services Routers reduce initial capital outlays by

decoupling the delivery of software from hardware on optional service modules. In addition, you receive a

Cisco IOS Software Universal image capable of enabling all of Cisco's rich Cisco IOS Software features and

allowing you to quickly deploy new services.

• Investment protection—The Cisco 2900 Series reduces deployment costs and increases flexibility. The

platform also offers investment protection with support for many existing ISR modules.

• The Cisco 2900 Series provides additional investment protection with Cisco Unified Border Element by

allowing enterprises to gracefully transition from legacy TDM Voice to IP-based Unified Communications

without the need for hardware upgrades.

• Energy efficiency—The Cisco 2900 Series architecture incorporates higher-efficiency power supplies with

intelligent power management, with full Cisco EnergyWise support in the future.

• High performance—The Cisco 2900 Series offers significant performance improvements over previous-

generation ISRs.

Overall, the Cisco 2900 Series offers unparalleled TCO savings and network agility through the intelligent

integration of security, wireless, unified communications, and application services.

Key Features and Benefits

The Cisco 2900 Series builds on the best-in-class offering of the existing Cisco 2800 Series Integrated

Services Routers by offering four platforms: Cisco 2901, 2911, 2921, and 2951 Integrated Services Routers.

All Cisco 2900 Series Integrated Services Routers offer embedded hardware encryption acceleration, voice-

and video-capable digital-signal-processor (DSP) slots, optional firewall, intrusion prevention, call processing,

voicemail, and application services. In addition, the platforms support the industry’s widest range of wired and

wireless connectivity options such as T1/E1, T3/E3, xDSL, copper, and fiber Gigabit Ethernet.

Key architectural features of the Cisco 2900 Series include:

•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.
