Peter, You are correct and thanks for the clarification. In my defense, allow me to point out my use of the word 'can' in my statement. Back to your clarification - I know that some (and not all as you correctly point out) European telcos use 60Vdc(72 charging). The rest to the best of my knowledge use 48. Your comment on German and Austrian locations does ring a bell but I am unsure what countries these voltages are used in or if it is carrier dependant and only networks owned by certain carriers have the higher voltages. I ran into these requirements back when I worked for an NRTL as many of my clients were Boston area networking companies with large distributions of products. Alas, as I was not part of the individual companies, I often did not hear where the products were to be shipped.
I figured that if someone was selling to Europe, they might as well plan for the worst case. Why exclude installation in some of the richest nations in the world?
