For example, a CUCM, Cisco Unified CMBE, or CUCM Express in San Jose can process call control for a device physically located in Chicago. Call processing is physically independent from the infrastructure layer. This book focuses on the CUCM product, which is almost identical to the Cisco Unified CMBE. This layer also provides high availability, management, quality of service (QoS), and network security.Ĭall control layer: The call control layer provides for call processing, device control, and administration of the dial plan and features.Ĭall control can be provided by a CUCM, CUCM Express, or CUCM Business Edition (CMBE). The infrastructure layer carries data, voice, and video between all network devices and applications. Infrastructure layer: The infrastructure consists of routers, switches, and voice gateways.The components of the standard layers are as follows: Instead of delivering a collection of disjointed products with individual release dates, testing methodology, and documentation, Cisco UC is a coordinated release of an integrated set of products that are tested, documented, and supported as a system.įigure 1-1 illustrates the four standard layers of the Cisco UC voice infrastructure model and the components that make up the layers.įigure 1-1 Cisco Unified Communications Solution Components Cisco UC equipment is capable of managing all three traffic types and interfacing with all standards-based network protocols.Ĭisco IP Communications represents a new way of delivering UC functionality to enterprise customers. The Cisco UC strategy encompasses voice, video, and data traffic within a single network infrastructure. More effective communication leads to reduced time to market and nimble transformation of business processes through collaboration. Information has been at our fingertips for a long time, but UC enables the sharing of this information to create knowledge and value.Ĭisco UC is part of an integrated solution that includes network infrastructure, security, mobility, network management products, lifecycle services, flexible deployment and outsourced management options, end-user and partner financing packages, and third-party communication applications.Ĭisco UC can drastically change the bottom line of business by creating more effective communications without losing the personal nature of a face-to-face conversation. Business can be conducted with a fluidity that progresses and evolves with you. UC removes the geographic barriers of effective communications through the use of voice, video, and data integration. UC represents a communications paradigm shift like that of the invention of the telegraph. It enables more effective, secure communications and can transform the way in which we communicate. Cisco Unified Communications (UC) is an IP-based communications system integrating voice, video, data, and mobility products and applications.
