Cisco 3900 Series Integrated Services Routers
Lets discuss about the Cisco 3900 Series router who is the replacement of Cisco 3800 Series router. So probably it is used where we have the WAN requirement is almost 150 Mbps or 200 Mbps ( Ethernet and Dedicated Circuits )
The Cisco 3900 Series router builds on the best-in-class offering of the existing Cisco 3800 Series Integrated Services routers by now offering four platforms (Figure 1): the Cisco 3945E, Cisco 3925E, Cisco 3945, and Cisco 3925 Integrated Services routers.
The Cisco 3900 Series offers embedded hardware encryption acceleration, voice- and video-capable 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.
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.
The Cisco 3900 Series router is architect 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 supporting 802.3af PoE and Cisco ePoE. Table 2 lists the architectural features and benefits of the Cisco 3900 Series router.
The Cisco 3900 Series provides significantly enhanced modular capabilities while maintaining investment protection for customers. Most of the modules available on previous generations of Cisco router, such as the Cisco 3800 Series Integrated Services routers, are supported on the Cisco 3900 Series.
Additionally, modules used on the Cisco 3900 Series can easily be supported on other routers in the Cisco Integrated Services router portfolio to provide maximum investment protection. Taking advantage of common interface cards across a network greatly reduces the complexity of managing inventory requirements, implementing large network roll-outs, and maintaining configurations across a variety of branch-office sizes.

Cisco IOS Software
Cisco 3900 Series Integrated Services routers deliver innovative technologies running on industry-leading Cisco IOS Software. Developed for wide deployment in the world’s most demanding enterprise, access, and service provider networks, Cisco IOS Software Releases 15M and T support a comprehensive portfolio of Cisco technologies, including the functions and features delivered in Releases 12.4 and 12.4T.
New innovations in Release 15.0(1)M span multiple technology areas, including security, voice, high availability, IP Routing and Multicast, quality of service (QoS), IP Mobility, Multiprotocol Label Switching (MPLS), VPNs, and embedded management. Available immediately for the Cisco 3900 Integrated Services Routers, Release 15.0(1)M will be an extended support release.

Cisco IOS Software Licensing and Packaging
A single Cisco IOS Universal image encompassing all functions is delivered with the platforms. You can enable advanced features by activating a software license on the Universal image.
In previous generations of access routers, these feature sets required you to download a new software image. Technology packages and feature licenses, enabled through the Cisco software licensing infrastructure, simplify software delivery and decrease the operational costs of deploying new features.

Four major technology licenses are available on the Cisco 3900 Series Integrated Services Routers. The following licenses are available:
- IP Base: This technology package is available as default.
- Data
- Unified Communications
- Security (SEC) or Security with No Payload Encryption (SEC-NPE)

Unified Communications, Collaboration, and Voice-Gateway Services
The Cisco 3900 Integrated Services Router is the foundation for collaboration in branch offices of any size and is a critical component of Cisco’s video architecture and enterprise Unified Communications solution.
With embedded voice services and a wide range of telephony interfaces supported, the Cisco 3900 Series delivers maximum deployment flexibility for the distributed enterprise. Unified communications is enabled through a rich signaling and media-processing infrastructure, including a variety of protocols, media interworking, signal and media security, transcoding, conferencing, and QoS.
Cisco Integrated Services Routers feature a wide range of voice-gateway interfaces, supporting a broad array of signaling and physical network interfaces. The performance improvements introduced with the Cisco 3900 Series help ensure that branch-office employees benefit from the same productivity advantages and wide breadth of services and applications as those enjoyed by the headquarters-based employees.

The Cisco 3900 Series enables a full range of existing and emerging video services, with scaling improvement to support Cisco TelePresence conferencing, security, and session control. Cisco Unified Border Element extends these capabilities for business-to-business TelePresence communications.
The Cisco 3900 Series adds support for the new Cisco High-Density Packet Voice Digital Signal Processor Module (PVDM3), which has been optimized for concurrent voice and video support. The PVDM3 modules support all voice-gateway functions of earlier generations of PVDMs, and add higher density and more processing power to support emerging rich-media applications. The Cisco 3900 Series can support up to 4 onboard PVDM3 slots, able to scale up to 768 G.729a channels
Integrated Network Security for Data, Voice, Video, and Mobility
Security is essential to protect a business’ intellectual property while also ensuring business continuity and providing the ability to extend the corporate workplace to employees who need anytime, anywhere access to company resources.
As part of the Cisco Self-Defending Network (SDN) - an architectural framework that allows organizations to identify, prevent, and adapt to network security threats - the Cisco 3900 Series Integrated Services Routers facilitate secure data transactions and secure collaboration.
