Cisco 2900 Series Cisco IOS Software Cisco 2900 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, the Integrated Services Routers Generation 2 platforms are supported on Cisco IOS Software releases 15M&T. Release 15.0(1)M is available immediately and provides support for a comprehensive portfolio of Cisco technologies, including the functionality and features delivered in releases 12.4 and 12.4T. New innovations in 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. Cisco IOS Software Licensing and Packaging A single Cisco IOS Universal image encompassing all IOS technology feature sets 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 2900 Series Integrated Services Routers; you can activate the licenses through the Cisco software activation process identified at http://www.cisco.com/go/sa. The four licenses are as follows: • IP Base: This technology package is available as default • Data • Unified Communications • Security (SEC) or Security with No Payload Encryption (SEC-NPE) For additional information and details about Cisco IOS Software licensing and packaging on Cisco 2900 Series Integrated Services Routers, please visit: http://www.cisco.com/go/2900l For a more comprehensive list of features supported in Cisco IOS software refer to the Feature Navigator tool at: http://www.cisco.com/go/fn. Key Branch-Office Services The Cisco Integrated Services Routers are industry-leading platforms that offer unprecedented levels of services integration. Designed to meet the requirements of the branch office, these platforms provide a complete solution with voice, video, security, mobility and application services. Businesses enjoy the benefit of deploying a single device that meets all their needs, reducing capital and operational expenses. Unified Communications, Collaboration, and Voice-Gateway Services The Cisco 2900 Integrated Services Router is the foundation for collaboration in the small and midsize branch office, serving as a critical component of a Cisco's video architecture (Medianet) and enterprise Unified Communications solution. With embedded voice services and a wide range of supported telephony interfaces, the Cisco 2900 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 also feature a wide range of voice-gateway interfaces, supporting a broad array of signaling and physical network interfaces. The Cisco 2900 Series enables a full range of existing and emerging video services, with scaling improvements to support Cisco TelePresence® conferencing, security, and session control. The Cisco Unified Border Element extends these capabilities for business-to-business TelePresence communications. The Cisco 2900 Series adds support for the new Cisco High-Density Packet Voice Digital Signal Processor (DSP) Module (PVDM3), which has been optimized for voice and video support. The new 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 2900 Series provides 2 or 3 onboard PVDM3 slots, depending on the platform. 96 Cisco 2900 Series Cisco IOS Software continued Cisco Unified Communications Manager Express and Survivable Remote Site Telephony The Cisco Integrated Services Routers natively provide optional unified communications services within the Cisco IOS Software, minimizing the IT hardware footprint and total cost of ownership at the branch office. Cisco Unified Communications Manager Express (CME) provides a broad range of IP private-branch-exchange (PBX) and key-system features integrated into the router for the small and midsize branch office. Cisco Survivable Remote Site Telephony (SRST), also inherently available in Cisco IOS Software, and an option on the Cisco 2900 Series, helps ensure that branch-office employees have uninterrupted telephony services and features, even if the connection to a centralized Cisco Unified Communications Manager is disrupted. Coupled with Cisco Unity® Express, the integrated solution for voicemail, Automated Attendant, and interactive voice response (IVR), the Cisco 2900 Series offers the branch office a complete range of unified communications services while delivering industry-leading security within a single platform. VoiceXML Application Services The Cisco 2900 Series also supports standardscertified VoiceXML browser services. VoiceXML is an open-standard markup language used to create voice-enabled web browsers and IVR applications. Just as HTML enables you to retrieve data with a PC, VoiceXML enables you to retrieve data using voice or dual-tone-multifrequency (DTMF) telephony input. The Cisco 2900 Series can deliver a much higher range of concurrent voice-gateway services combined with VoiceXML browser services, for up to 200 sessions on the Cisco 2951. Cisco Unified Border Element The Cisco Unified Border Element capabilities supported on the Cisco 2900 Series address the emerging requirements in an IP-centric interconnect for branch-office unified communications between enterprises and service provider networks. Cisco Unified Border Element provides intelligent border-element functions such as physical and logical ingress and egress demarcation points, signaling and media control, and consolidated security and management features. The Cisco 2900 Series supports higher scale than previously provided on the Cisco 2800 Series, up to 3 times the number of sessions. 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' SAFE architectural framework that allows organizations to identify, prevent, and adapt to network security threats, the Cisco 2900 Series Integrated Services Routers facilitate secure business transactions and collaboration. The Cisco IOS Software Security technology package for the Cisco 2900 Series offers a wide array of common security features such as advanced application inspection and control, threat protection, and encryption architectures for enabling more scalable and manageable VPN networks. The Cisco 2900 Series offers onboard hardware-based encryption acceleration to provide greater IPsec throughput with less overhead for the route processor when compared with softwarebased encryption solutions. Cisco Integrated Services Routers offer a comprehensive and adaptable security solution for branch offices that includes features such as: • Secure connectivity: Secure collaborative communications with Group Encrypted Transport VPN, Dynamic Multipoint VPN (DMVPN), or Enhanced Easy VPN • Integrated threat control: Responding to sophisticated network attacks and threats using Cisco IOS Firewall, Cisco IOS Zone-Based Firewall, Cisco IOS IPS, Cisco IOS Content Filtering, and Flexible Packet Matching (FPM) • Identity management: Intelligently protecting endpoints using technologies such as authentication, authorization, and accounting (AAA) and public key infrastructure (PKI) Detailed information about the security features and solutions supported on the Cisco 2900 Series is available at http://www.cisco.com/go/ routersecurity. 97
