Best of breed: telecom training -  since 1992



An intensive three-day modular course covering all major topics in telecom, datacom and networking. 

Telecom, Datacom and Networking for Non-Engineering Professionals is our "core training" - an intensive three-day course designed for non-engineering professionals, to get you up to speed on virtually all aspects of telecom, datacom and networking, from fundamentals and jargon to the latest technologies.

Thousands of people from organizations including Cisco, Intel and Microsoft, the CIA, IRS, FAA, and FBI, all branches of US Armed Forces, Verizon, AT&T, TELUS and Qwest, Wells Fargo, Bank of America, TD Bank, Oneida Tableware, the Portland Trailblazers and hundreds of others who needed to be more effective in understanding and dealing with telecom and networking technology have benefited from this course.  

The content, its order, our analogies and explanations have been refined over the course of twenty years… and we constantly update it.

·  We start at the beginning of the story, progress through it in a logical order, and finish at the end. 

·  We bust the buzzwords, explain the jargon, and more importantly, the ideas and concepts behind the jargon: key concept-level knowledge that you can’t get on the job, from magazines or vendors. 

·  Covering the topics in a systematic way, we build structured knowledge that lasts a lifetime. 

This core training - and our superb instructors - consistently receive rave reviews on evaluations. 
Many attendees tell us that this is training they wish they’d had years ago!
