I started out as a Telecommunication Technician
Spent years working on juke boxes, pinballs, video games and pool tables.
Then a year as a tech on Office Equipment
Then a couple of years as a Computer hardware tech for a university where I also studied at that time also part time teaching introductory electronics at a TAFE (adult education place).
Moved states and worked as a Data Communications Officer for a couple of Govt Depts.
The Govt outsourced the Data Communications and some of us went to the contractor so I spent time as an Internetworking Specialist.
Then back to the Govt working for the Education Department first as a help centre manager then back to data communication where I was tasked with transforming the way all data and voice comms were done.

Then retired.

Basically always working in some form of voice or data communications.

Picked up several qualifications on the way including an Assoc Dip App Sc (Computing), Cisco Certified Network Professional (CCNP), a number of Electronic and Communications Certificates and also several Computer related papers.

You got most of it.
