Perry Bebbington. Living in Nottingham in the UK. Main expertise is in electronics and telecommunications, and I'll write on those subjects as and when I see something that I vaguely know anything about with a ? next to it.
Created the original entries for PDH, SDH, multiplexer, inverse multiplexer and enjoying seeing others adding to and improving my entries even after just a few days! Pity I did them before I got my username sorted out though.
Feel free to leave me messages on this page.
Perry, I responded to your query on my talk page (sorry for the delay!) Verloren
