TMC awareness and understanding of Network Infrastructure plays a role of importance and value associated with the business. With a Network Infrastructure architecture is well planned, designed according to standard hierarchical model Access, Distribution and Core layer will assume the role of backbone for enterprise networks.

At the same time networks are growing exponentially, they are becoming complex and mission critical, bringing new challenges to those who run and manage them. The need for integrated network infrastructure comprising voice, video, and data (all-in-one) services is evident, but these rapidly growing technologies introduce fresh security concerns. Therefore, as network managers struggle to include the latest technology in their network infrastructure, network security has become a pivotal function in building and maintaining today\'s modern high-growth networks.

A Cisco Unified Communications (UC) deployment relies on Cisco Unified Communications Manager (CUCM) for call processing, device control, call routing, mobility services, phone/system feature administration, and dial plan administration.
Understanding the role that CUCM plays in a UC deployment to provide the essential call-routing functions necessary to deploy voicemail, unified messaging, presence, video to the desktop, videoconferencing, TelePresence, and cloud-based services such as those provided by Cisco WebEx Connect is integral to the success of UC.
