Since its inception at the Xerox Palo Alto Research Centre in California in the 1970s, Ethernet has become the pervasive technology for electronic communications in offices, universities and homes. Ethernet is now also used for longer distance communications linking offices in different towns and cities.

PTT has just released two updated courses covering Ethernet. The first course LAA: “Ethernet fundamentals” is designed for those involved in the installation and testing of Ethernet local area networks. LAB: “Ethernet networks” provides a more in-depth treatment of  Ethernet for those involved in network design and maintenance and includes information about “Carrier Ethernet”.
