Hi @Anonymous User
The broadband advertising rules have changed recently where Average speeds are now quoted rather than maximum speeds which is better in my opinion because there are so many variables that effect internet speeds and it is difficult to quote accurate figures (see article linked below).

From my memory before the changes, i believe the maximum "Access line speeds for nowtv fab fibre was 40mbps down and 10mbps up (might be wrong thou and don't take this has gospel where i would rather somebody from the nowtv team to give you a more definitive answer).
The distance from the local green BT cabinet is literally outside my house and i am getting the full fat 40mbps / 10mbps speeds 
Hi @Anonymous User
To be honest i don't know maybe try googling the question in your internet browser search engine.
When i access my Hub 2 router settings and under status logs i am not seeing anything that says either G.992 or G.993 (maybe i am not reading the log status entries correctly which is all above my head 
).
Have you spoken to the nowtv broadband team about this and when you provisionally enquired about Fab Fibre what average speeds was you quoted before signing up to nowtv from your post code home address ?
