OK, so engineer has been and gone.
First thing, its the damn ECI modem, so no stats there for me
Secondly, the engineer said that there were quite a few RS errors showing on his JDSU and that DLM would already be slowing down the line from his initial connection which synced up at 37Mbps. He tried to do some tests but said that BT's system was unavailable today and that he had been unable to use it all day !! He did however mention that my copper is quite noisy (which I already knew) and told me which CAB I am connected to. I was suprised to find it wasn't the one I thought it would have been, and he said that he was suprised as well, as he had originally gone to the one I thought it would have been. The other cab (that I am connected to) is in totally the opposite direction to the exchange and further away from my house too
Anyways, speedtest from around 15 minutes after initial JDSU connection.
Original speed estimate was 33Mbps but he said it was more likely that it would settle around 30, judging by his stats. He did show me his JDSU but wouldn't let me photo it.
