Yep, this is a point I have been making.  Bell will have fibre to 
somewhere in your neighbourhood and copper from there.  This has been 
done for years.  What difference do you expect between this and a copper 
pair all the way back to the CO?

It still goes back to how connections are made and the bandwidth etc..  
Bell has to provide a standard toll quality circuit.  That used to be 
over copper all the way from the CO.  Now it could be from a terminal in 
a home, as I have with Rogers.  Either way, it's still a toll quality 
connection.  Here's an article about the G.711 CODEC, which describes 
what's expected from a phone circuit, no matter who provides it and 
how.  Even ancient analog systems provided similar.
