The new routers aid new higher-potential electronic sign processors (DSPs) for long term enhanced video clip features, higher-driven service modules with improved availability, multicore CPUs, Gigabit Ethernet switching with Cisco Enhanced Electric power in excess of Ethernet (ePoE), and new energy visibility and management abilities while improving total program effectiveness. Moreover, a new Cisco IOS® Software program Common image and Cisco Companies Ready Engine (SRE) module help you to decouple the deployment of components and software program, offering a flexible technologies basis that can quickly adapt to evolving network specifications. General, the Cisco 3900 Series gives fantastic full expense of ownership (TCO) savings and community agility as a result of the intelligent integration of marketplace-top security, unified communications, wireless, and application providers.

The Cisco 3900 Series builds on the ideal-in-course providing of the current Cisco 3800 Series Built-in Services Routers by now presenting 4 platforms (Figure one): the Cisco 3945E, Cisco 3925E, Cisco 3945, and Cisco 3925 Integrated Companies Routers. The Cisco 3900 Series delivers embedded hardware encryption acceleration, voice- and video clip-able DSP slots, optional firewall, intrusion prevention, phone processing, voicemail, and application services. In addition, the platforms assist the industry's widest variety of wired and wireless connectivity selections these as T1/E1, T3/E3, xDSL, copper, and fiber Gigabit Ethernet. The Cisco 3900 Series provides remarkable effectiveness and flexibility for versatile community deployments from small company places of work to big business places of work - all while delivering business-primary investment decision defense.

• The Cisco 3900 Series routers offer you elevated ranges of solutions integration with voice, video clip, safety, mobility, and knowledge expert services. • The Cisco 3900 Series offers the highest performance and slot densities amid the routers in the Cisco ISR G2 portfolio, enabling you to optimize providers integration and lowering general richesse expenditures (CapEx) and functioning expenditures (OpEx).

• A solitary Cisco IOS Software Universal image is mounted on just about every Cisco ISR G2. The Common picture consists of all of the Cisco IOS Software technological innovation sets, which you can activate with a software license. With the Common picture your enterprise can swiftly deploy innovative features with out downloading a new Cisco IOS Software program image. Moreover, bigger default memory is bundled to support the new capabilities. • The Cisco SRE permits a new operational model that allows you to lessen CapEx and deploy a selection of application solutions as essential on a single built-in compute solutions module.

Significant overall performance with built-in companies

• The Cisco 3900 Series lets deployment in large-speed WAN environments with concurrent solutions enabled up to 350 Mbps. • A multigigabit fabric (MGF) enables significant-bandwidth module-to-module communication without compromising router functionality.

Network agility

• Intended to tackle customer organization necessities, the Cisco 3900 Series with the modular architecture provides elevated ability and efficiency as your community demands expand. • The Cisco Companies Functionality Motor (SPE) modular motherboard lets upgrades to processing ability in the upcoming. • Dual built-in electricity materials supply electrical power redundancy you can also configure them to present more Cisco ePoE electrical power to endpoints. • Modular interfaces present increased bandwidth, a range of connection options, and network resiliency.

Strength efficiency

• The Cisco 3900 Series architecture offers electricity-cost savings attributes that incorporate the next: • The Cisco 3900 Series delivers clever electrical power conduite and allows you to manage electrical power to the modules dependent on the time of day. Cisco EnergyWise technologies will be supported in the long term. • Solutions integration and modularity on a single system allows you to execute multiple functions, optimizing use of uncooked resources and electricity use. • System versatility and ongoing progress of the two components and computer software abilities lead to a lengthier item lifecycle, lowering all aspects of the TCO - such as materials and strength use. • Higher-effectiveness energy materials and scalable energy intake are dependent on your community requirements.

Expense safety

• The Cisco 3900 Series maximizes financial commitment defense by supporting: • Reuse of a broad array of present modules supported on the original Cisco Built-in Companies Routers to provide a decrease TCO. • A rich established of Cisco IOS Software characteristics carried ahead from the original Cisco Integrated Services Routers and delivered in a simple universal picture. • The Cisco 3900 Series gives extensive progress options as your network expands: • The SPE modular motherboard enables flexibility for foreseeable future upgrades. • The best scale for module density supplies overall flexibility to add expert services as your business desires grow. • A 1-Gb default memory gives headroom to reduce discipline upgrades.

Platform Architecture and Modularity The Cisco 3900 Series is architected to meet the software demands of today's department offices with layout overall flexibility for future programs. The modular architecture is intended to assist increasing bandwidth requirements, time-division multiplexing (TDM) interconnections, and fully built-in electricity distribution to modules supporting 802.3af PoE and Cisco ePoE. Table two lists the architectural attributes and advantages of the Cisco 3900 Series.

• The Cisco 3900 Series routers are hugely modular platforms with numerous kinds of module slots to add connectivity and providers for diverse department-office community demands. • The routers offer an industry-major breadth of LAN and WAN connectivity alternatives by way of modules to accommodate discipline upgrades to foreseeable future technologies devoid of necessitating system substitute. • The Cisco SPE on the Cisco 3900 presents the capability to improve the effectiveness of the router with a subject-upgradable motherboard as your community desires develop.

Processors

• The Cisco 3900 Series routers are powered by significant-functionality multicore processors that can assistance the developing demands of significant-speed WAN connections to the department workplace although also working several concurrent services.

Embedded IP Safety with Secure Sockets Layer (IPSec/SSL) VPN components acceleration

• Embedded hardware encryption acceleration is improved to offer larger scalability, which, blended with an optional Cisco IOS Computer software Security license, lets WAN website link safety and VPN companies (both IPSec and SSL acceleration). • The onboard encryption components outperforms the superior integration modules (AIMs) of preceding generations.

Multigigabit cloth (MGF)

• The Cisco 3900 Series introduces an revolutionary MGF that enables for productive module-to-module communication, enabling tighter solutions interactions across modules while cutting down the overhead on the router processor.

TDM interconnectivity material

• Unified communications providers in the department place of work are appreciably enhanced with the use of TDM interconnectivity fabric in the router architecture, enabling for scaling of DS- channel capacity.
