This 1.5 day course for non-engineering professionals will provide an overview of the telecommunications industry and rapidly changing technology. This is a basic course, so experience within in the telecommunications industry is not required.  It is designed for anyone new to the world of telecommunications or for those who have traditionally supported the data side of the business, which now includes telephony.  It is also very applicable to telecommunication professionals who have tenure, yet find their traditional roles changing with the collaboration and cross functional support that is needed for today’s telephony environment. 

Consumers are demanding new and faster ways of communicating and corporations are struggling to keep up. The focus on application integration and the impact of the “cloud” is changing the way we do business and the technology required to support it.  Who’s responsible for what?  Why and how is “real-time communications” different from data communications?  Join us to gain clarity on today’s confusing landscape and prepare to set your sights on the Next Generation Technologies. 

In addition to the knowledge gained in this course, attendees will depart with valuable resources and industry inks.  These tools will provide the opportunity for ongoing research and increased knowledge. 

This course is designed to encourage questions from the participants.  It will be fun and interactive, however no individual will be called upon or singled out.  Some PowerPoint slides will be used to illustrate important points; however, it will not be death by PowerPoint and full of dry bullets. 

The course will cover the following:

  • The history of the telephone industry and telephony regulation and why it still matters
  • The historical breakup of the Bell System and its lasting impact
  • Understanding the Public Switched Telephone Network (PSTN) and underlying technology
  • The technology behind the migration of the old telephony network to today’s IP-PSTN
  • The technical details related to the transformation from analog, to digital, to Voice over IP (VoIP)
  • The fundamental telephone service concepts needed to support real-time communications
  • The physical networks needed for real-time communications
  • The nature of LANs, MANs, and WANs and the role in connecting users and services
  • Advanced technology such as Fiber to the Premise (FTTP) and Wave-Division Multiplexing
  • Premises-based systems vs. cloud technology
  • SIP trunks, Web-RTC and Software Defined Networks
  • Unified communications and collaboration
  • The key players in today’s marketplace
  • Next Generation Technologies; where do we go next?
  • What does it all mean to the attendee
