Unified Communications
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.
Cisco integrated services routers offer the award-winning Cisco Unified Communications Manager Express (CUCME) IP telephony solution for wired and cordless wireless LAN (WLAN) phones. For larger, centralized Unified Communications deployments employing Cisco Unified Communications Manager, one can deploy Cisco Unified Survivable Remote Site Telephony (SRST) with the Cisco 3800 Series Routers. SRST provides high availability with feature-rich call-processing redundancy in the event connection to the centralized Cisco Unified Communications Manager is lost. Cisco Unity Express provides integrated branch office messaging capability. Cisco Unified Border Element (CUBE) can be deployed for connecting to service provider Session Initiation Protocol (SIP) trunk solutions or across various unified communications solutions. Small offices and branch offices can take advantage of a complete, all-in-one data, voice-processing, voicemail, and Automated-Attendant system by adding a Cisco Unity® Express advanced integration module (AIM) or network module to this solution.
Cisco 3800 Series Routers also feature the widest range of voice-gateway interfaces, scaling to meet the requirements of all sizes of branch offices for voice termination densities using a combination of SIP trunk software, network modules, extension voice modules (EVMs), voice interface cards (VICs), voice/WAN interface cards (VWICs), and onboard packet voice DSP modules (PVDMs). These routers offer scalability to support up to 24 T1/E1 trunks and 88 foreign-exchange-station (FXS) ports for analog phones, fax machines, key systems, and conference stations.
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.
Wireless LAN and WAN Services
The Cisco 3800 Series can provide a complete wireless solution for branch offices, companies of all sizes, and Wi-Fi hotspots. Wireless services enable greater mobility for employees, partners, and customers, resulting in increased productivity. The Cisco 3800 Series supports an integrated access point for WLAN connectivity, Wi-Fi hotspot services for public access, wireless infrastructure services for cordless WLAN telephony and for larger sites, and land mobile radio over IP (LMRoIP) for radio users.
The Cisco 3G WWAN High-Speed WAN Interface Cards (HWICs) are tightly integrated with the services provided on the award-winning Cisco 3800 Series Integrated Services Routers, which deliver secure data, voice, video, and mobility services. When coupled with a service provider wireless data plan, the Cisco 3G WWAN HWICs provide a cost-effective, rapidly deployable, reliable, and secure backup solution for remote sites and branch offices. With data rates exceeding T1 speeds, third-generation (3G) networks provide an alternative to wireline backup solutions such as ISDN, cable, and DSL. If a network failure occurs, the Cisco integrated services router routes mission-critical data to the Cisco 3G WWAN HWIC for transmission across the wireless infrastructure. In addition, the router can distinguish different types of traffic and allow only mission-critical traffic to flow over the backup interface.
Video Surveillance
The Cisco Integrated Video Surveillance solution enables you to rapidly deploy highly distributed IP-enabled video surveillance at your offices while migrating traditional analog surveillance equipment to IP. Based on Cisco 2800 and 3800 Series Routers, the solution offers the lowest total cost of ownership (TCO) for the branch office, ease of integration through network transparency, reliable data interoperability, and maximized overall security. It allows you to consolidate costly branch-office servers and deploy new applications centrally while still offering real-time access to physical security video and data.
Integrated Services
Figure 2 also highlights the fact that with the unique integrated services architecture of the Cisco 3800 Series, you can securely deploy IP communications with traditional IP routing and still leave the network-module slots available for additional advanced services. With the optional integration of a wide array of services modules, the Cisco 3800 offers the ability to easily integrate the functions of standalone network appliances and components into the Cisco 3800 Series chassis itself. Many of these network modules, such as the Cisco Network Analysis Module (NAM), the Cisco Intrusion Prevention System (IPS), and Cisco Wide Area Application Services (WAAS) Network Modules, have embedded processors and hard drives that allow them to run largely independently of the router, while allowing their management from a single management interface. This flexibility greatly expands the potential applications of the Cisco 3800 Series beyond traditional routing while still maintaining the benefits of integration: ease of management, lower solution costs, and increased speed of deployment.
Application Integration
The Cisco Application eXtension Platform (AXP) enhances the capabilities of the Cisco ISR 3800 by enabling a tighter integration between the branch network, IT and application infrastructure. The Cisco AXP further lowers TCO by providing an open Linux based platform to develop and host custom and third party applications directly on the Cisco ISR. The Cisco AXP provides a standards-based Linux hosting environment within the integrated services router, allowing third parties to integrate applications with the router. Tightly integrated, the AXP environment is configured and managed through the router. Harnessing this integration, an AXP application can appear to the end user as an extension of the router.
