The glich doesn't happen any time a ADSL circuit is in the same count as an ADSL2+ circuit. In fact, ADSL and ADSL2+ are deployed from the same DSLAM- if that were true, none of the ADSL out of a DSLAM offering ADSL2+ would work very well.

It apparently occurs in a specific circumstance- when a longer ADSL line from the CO is in the same count as a shorter ADSL2+ one.

Really?

You are the one that hasn't a clue. Do you even know what crosstalk is? How about a db (decibel)? Hint: BELL
