Image data not correct?
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: etc. --78.87.110.161 (talk) 23:09, 19 April 2014 (UTC)
 * 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?
