Please explain.In reply to a post by Anonymous:The 39999 and 9999 figures are those actually in the cabinet, It's impossible for almost anyone to achieve those speeds.
There is no VDSL2 signal from the exchange to the cabinet. The VDSL2 is output from the cabinet DSLAM down the copper to the premises.
I would be very interested to know how the sync at the cabinet can be 39999/9999 but different at the user premises. Now; what is "sync" short for again ...?
