Seminar Brochure

You will learn how to

• Apply multiple communications technologies in planning convergence networks for voice, data and video
• Choose the correct wired or wireless transmission medium for network access
• Specify the most cost-effective telephony network technologies for your enterprise
• Take advantage of Internet technology to handle your data and voice communications
• Evaluate current data network alternatives for cost-effective technical support

Course benefits
Today's telecommunications networks have the ability to transport voice, data and image traffic to any location in the world. While most organizations use many separate networks for the various types of information they exchange, many are moving toward convergence of several types of traffic into fewer networks.

This comprehensive introductory course demystifies all of the components and standards of today's telecommunications options. You learn how to evaluate your organization's choices and develop a strategy that achieves the best balance between cost, security and performance for each type of traffic.

Who should attend
This course is valuable for those involved in projects requiring the transmission of voice, data and video over wide area networks.
