ADSL Task: So did I Mike. If you start the task right now you see ADSL as a menu of choices. If see it as a constant development over the last 3/4 years you see a technology maturing.
This is how I got comfortable with my ADSL task:
Please, correct if I'm wrong:
1) ADSL full rate developed with Video distribution in mind
2) ADSL low rate 1.5Mbit/s for data
3) SDSL low rate 1.5 Mbit/s for data symetrical because business users required it.
4) ADSL integrated into the switch (Lucent 5ESS Anymedia and Siemens EWSD Internode) to get rid of double pasing in the MDF.
4) ADSL lite because some one wanted to use it in lap tops
5) VoADSL because we get rid of splitters and the MDF. Hand over the TDM signals and don't bother with voice all the way over packet and get rid of latency.
6) VDSL because of fiber penetrating deeper into the Last Mile -right to the users' neighborhoods over fiber- from there on (only 500 to 300m) over copper could go at ADSL 25Mbit/s.

Please, note that ADSL depends -and is aimed at- on the infrastructure of incumbents which have not yet lost their monopolistic behaviour, they have screwed up the first digital subscriber line and are doing quite a good job on this one as well.
