Visitor’s Information Page

Preface:  This content started development in 1991 as a “spare-time” project for Timeplex’s TAC center (Technical Assistance Center) in Clearwater, FL .  It ran under Novell’s “Folio Views” menu-based help system.   I converted much of the content to Hypertext with the first release of the Mosaic browser for Windows towards the end of 1993.  

Wherever possible, I will preserve the exact text of the original sources to preserve the young, entrepreneurial spirit in which these articles were written.  Enjoy!


Welcome to the Telecom Corner! This site provides useful, self-study information about telecommunications. It’s best to use Netscape’s Communicator/Navigator 4.05 or Microsoft’s Internet Explorer 4.X for viewing this site.

This site presents Telecommunications information in 6 general categories:

  • Multiplexing
  • Transmission
  • Networking
  • Switching
  • Modulation
  • History

As the reader will notice, there is a lot of cross-linking between these categories. Ah, but that’s what makes the business fun! It can, however, make browsing the site difficult when using the RETURN button at the top of each page. Please make use of your browser’s Back and Forward buttons.
