When studying for my Cisco ISCW exam, I wanted to get somewhat more in-depth information on the different DSL-techniques.
First of all, there are different DSL techniques, ranging from IDSL (providing 144/144kbps) over the popular ADSL (somewhere around 1/10Mbps up/down) up to the newer VDSL variants (around 50Mbps). Within each technique, there are different modulation schemes.
I decided to explore what my Alcatel SpeedTouch modem (now Thomson) had to tell me; here is the report.
