Telecom is undergoing a series of radical changes, molded by the legacy oftelephony and an Internet Protocol network. A new era in telecommunications hasexploded with the adoption of Wireless LAN, Unified Communications (UC), Voiceover IP (VoIP), 3G and 4G mobile networks, cloud computing, and the nextgeneration of voice and data services.

In this comprehensive course, you will gain an in-depth understanding of thecurrent telecom landscape and how voice has migrated from a circuit- to apacket-switched network. You will learn how to evaluate existing technologyoptions to determine which will best meet your organization's data and telephonyrequirements, from mature digital transport/access services to emerging voiceand data services using voice over packet technologies.

The technology, marketplace, and regulatory structure of telecommunicationsare in a continuous state of transition. This powerful course will ensure thatyou fully understand the service options available to your organization and howvoice technologies integrate into your existing data networks.
