Yes I have got experience on both Data and Voice Solutions in both the TDM and IP Categories. However, I do not possess any certifications.
I have also worked on PON, GEPON, HFC, EOC, DWDM, SDH, DXX, OTN, PTN and FTTx etc.
As a matter of fact, I have done consultancies on the Design of Hybrid Last Mile Solutions.
I wish to start my own consultancy in Australia as an Entrepreneur but I am not sure about the limitations of Class 189/190 visas regarding this matter.
