Secure Network Connectivity for Data, Voice, and Video
An important component of the Cisco Self-Defending Network, the Cisco 3800 Series Routers feature the industry's most comprehensive security services embedded and integrated within the router, offering you a single, resilient platform to rapidly deploy secure networks and applications.
Cisco integrated services routers provide advanced security services and management capabilities such as built-in hardware encryption acceleration, IP Security (IPSec), VPN (Advanced Encryption Standard [AES], Triple Digital Encryption Standard [3DES], DES, and Multiprotocol Label Switching [MPLS]), stateful firewall protection, dynamic intrusion prevention (IPS), and URL filtering support. Cisco IOS® Software security feature sets enable all of these rich security features, as well as applications such as Cisco Network Admission Control (NAC), Dynamic Multipoint VPN (DMVPN), and Voice and Video Enabled VPN (V3PN).
For ease of management and configuration, the Cisco 3800 Series also features the intuitive, web-based Cisco Router and Security Device Manager (SDM) and Cisco Configuration Professional For secure services management, every Cisco integrated services router supports Secure Shell Protocol Version 2 (SSHv2) and Simple Network Management Protocol Version 3 (SNMPv3) to encrypt the management session.
Cisco integrated services routers provide a unique platform for media-rich collaboration experience, including voice, video, and data across business, government agency, and institutional workspaces. The security, resilience, and scalability of the network enables users in any workspace to connect everywhere, every time, and everyone. As shown in Figure 2, the Cisco 3800 Series meets the Unified communications needs of midsize to large enterprise branch offices, while delivering industry-leading security within a single routing platform. With embedded voice services inside the router, you have maximum deployment flexibility, plus higher densities for stations, trunks, and conferencing.
Unified communications (UC) is enabled via a rich signaling and media processing infrastructure, including a variety of protocols, media interworking, signal and media security, transcoding, conferencing, and quality of service. Cisco integrated services routers feature the widest range of voice-gateway interfaces, supporting a broad array of signaling and physical network interfaces. In addition, the Cisco Unified Border Element (CUBE) enables IP trunking capability. CUBE functions provide a network-to-network demarcation and interface point for billing, security, call admission control (CAC), quality of service (QoS), and signal interworking.
VoiceXML Solution Infrastructure
The Cisco 3800 Series Routers can interpret VoiceXML documents. VoiceXML is an open-standard markup language used to create voice-enabled Web browsers and IVR applications. Just as HTML enables users to retrieve data with a PC, VoiceXML enables subscribers to retrieve data using a telephone set. The accessibility of the telephone and its ease of use make VoiceXML applications a powerful alternative to HTML for accessing the information and services that the Internet provides. The Cisco VoiceXML Solution Infrastructure takes advantage of Cisco 3800 Series DSP resources, signaling, and media-conversion capabilities to execute VoiceXML application logic at the edge of the network, offloading servers and the network to support unified communications services.
The Cisco 3800 Series running a VoiceXML or TCL application can use Media Resource Control Protocol (MRCP) to control media resources on external media servers, such as speech synthesizers for text-to-speech (TTS) and speech recognizers for automatic speech recognition (ASR). The ability of this gateway to interact with ASR and TTS servers provides the capabilities required to satisfy the most demanding and advanced IVR solutions.
