Overview

Today's telecommunications networks transport voice, data, and image traffic over a multitude of legacy and emerging technologies. This comprehensive course provides you with information on the structure, architecture, components, standards, and design of modern voice/telephony networks. You will learn how to evaluate existing technology options to determine which will best meet your organization's data and telephony requirements, from mature digital transport/access services, to emerging voice and data services using voice over packet technologies (VoIP, VoFR, VoATM, etc.), to the latest in carrier services including Metro Ethernet, IP Centrex, and softswitch-based services.

Learn what makes up contemporary telephony networks: the history of the public switched telephone network (PSTN), the basic components of telephony networks, legacy and leading edge digital services, the hottest new voice over packet services, and the most current trends in mobile wireless communications. The technology, marketplace, and regulatory structure of telecommunications are in a continuous state of transition. This powerful course will ensure that you fully understand the service options available to your organization, and how voice technologies integrate into your existing data networks.
