Image data not correct?[edit]

Hi everyone, I just cross checked the data of this image and found many mistakes... Maybe someone with more knowledge should review the whole chart?? What I found:

  • VDSL2 goes until 30MHz
  • VDSL not in chart
  • VDSL and VDSL2 start from 640 kHz
  • Differences in ADSL with POTS and ISDN not mentioned at all
  • What is the grey upstream?
