Voice/Data I

Voice/Data I:
Understanding IP Networks for Data and VOIP

With network convergence becoming the inevitable direction in enterprise networks, IT and telecom departments must develop personnel with a broad range of expertise. Building IP-based networks to support both voice and data applications requires an in-depth understanding of the technologies, terminology, and network configurations that are used. The industry has undergone a major transition in the past decade with the convergence on IP, the widespread availability of broadband access, and the phenomenal growth of wireless networking. Each one of these new developments brings with it a set of capabilities and constraints that must be mastered. This program is designed to provide that essential foundation in data and IP networking and to bridge the gap between voice and data communications. While the topic areas may appear to be technical, the presentation geared to making the technologies and their advantages accessible and meaningful to business as well as technical managers.
