Chapter 1: Routing 1-5

Routing

that can quickly adapt to evolving network requirements. Overall, the Cisco 3900 Series offers exceptional 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 3900 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

Universal Cisco IOS Software 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 3900 Series reduces deployment costs and increases flexibility. The

platform offers a modular, field-upgradable motherboard called the Services Performance Engine (SPE).

SPEs allow you to invest in a Cisco 3900 Series ISR today and boost its performance later by upgrading to a

higher-performance engine. Investment protection is also offered with support for most existing modules

from previous-generation ISRs.

• The Cisco Unified Border Element features on the Cisco 3900 provides additional investment protection 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 3900 Series architecture includes higher-efficiency power supplies with

intelligent power management, with full Cisco EnergyWise feature support in the future. Both Cisco 3925

and 3945 routers support dual power supplies for power-supply redundancy for branch-office or retail

environments running mission-critical applications.

• High performance—The Cisco 3900 Series offers significant performance improvements over previous-

generation ISRs.

Overall, the Cisco 3900 Series offers unparalleled total-cost-of-ownership (TCO) savings and network agility

through the intelligent integration of security, wireless, rich media, and application services.
