Why is the upload speed for FTTP not symetrical with the download speed?
I can get my head around with FTTC and ADSL the bandwidth is limited by the line characteristics and more bands are possibly assigned to download, which makes sense.
But why would the FTTP not be 330 down / 330 up?
Surely all of the links in the BT network are symetrical so you would expect with the many 1000's of ADSL / FTTC connections there would be a significantly less upload use on the links compared to download use.
So why restrict the upload when on the face of it to me it seems there could be all of this unused capacity in the BT network??
