The buy cisco 3900 series, designed to power the next phase of branch-office evolution, builds on the best-in-class offering of the existing Cisco 3800 Series Integrated Services Routers by now offering four platforms: the Cisco 3945E, Cisco 3925E , and C3945-WAAS-SEC/K9 Integrated Services Routers.
Cisco 3900 router offers embedded hardware encryption acceleration, voice- and video-capable DSP slots, optional firewall, intrusion prevention, call processing, voicemail, and application services. C3945-VSEC-SRE/K9 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.
And the CISCO3925E-SEC/K9 also offers superior performance and flexibility for flexible network deployments from small business offices to large enterprise offices-all while providing industry-leading investment protection.
The CiscoISR G2 routers provide superior services integration and agility. Designed for scalability, the modular architecture of these platforms enables users to evolve and adapt with your growing business needs. Business benefits of the Cisco 3900 Series router are listed as follows:
Services On-Demand: The CISCO3925E-V/K9 router reduces initial capital outlays by decoupling the delivery of software from hardware on optional service modules. In addition, you receive a Universal IOS image capable of enabling all of Cisco's rich IOS 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 3900 Series ISR today and boost its performance later by upgrading to a higher-performance engine. Investment protection is also offered with support for a majority of existing modules from previous-generation ISRs.
Energy Efficiency: The Cisco 3900 architecture includes higher-efficiency power supplies with intelligent power management, with full Cisco EnergyWise feature support in the future. Both ISR 3925 and CISCO3945E-SEC/K9 routers support dual power supplies for power supply redundancy for branch or retail environments running mission-critical applications.
High Performance: The Cisco 3900 Series router offers significant performance improvements over previous-generation ISRs. CISCO3945E-V/K9
