This one day Telecom 101 course explains and demystifies the terms used, and the technologies, functions and components that make up the complex world of the voice and data telecommunications networks. So much has happened historically, the buzz words and three letter acronyms that the experienced take for granted can be overwhelming.

From Plain Old Telephone Service, to the Internet, to the regulatory environment, this course provides a complete survey and reference for the terms, the network equipment functions, and the components that make up the complex world of voice and data telecommunications.

Target Audience
