What are your line stats now and what were the before?
I don't know as I can no longer use the DMT tool like I did when I was with O2.
From memory my downstream attenuation was 53 dB and my upstream attenuation was around 33 dB.
I wouldn't expect these values to change much if at all ?
I expect the upstream will also have a higher SNR margin, probably 7db like the downstream.
Oh well it isn't that important as when my exchange is upgraded to FTTC, I will upgrade assuming I am able to i.e. the green cabinet that my house is connected to gets the FTTC treatment !
