Unfortunately the Zen site does not give line synch (that I could find) on FTTC deployments only IP Stream services.
I have already spoken to tech. Not sure if BRAS is incorrect thats a good point.
On a different note, however, Zen Support did mention to me that OR had done some work on my line on the 21st March 2011 which coincides with the drop in speeds. I went live on FTTC in December 2010 so this is work 3 months AFTER go live date so I know what the line should deliver now. I also have an ISP background from a sales perspective so whilst no engineer, I do know a bit about this....
Interestingly, I was earlier talking to a friend who has FTTC by a different SP and recently his speeds have suffered in the same fashion as mine and the dates of noticing it are broadly similar.
This means that work carried out in my LX potentially account for the same issue I am describing on another FTTC account down the road with a different ISP.
Points towards an OR wire missing in the Local Exchange maybe (its at this point that engineers are needed to provide an answer not someone who knows enough to "sound" knowledgeable).
