Hi EGTE
Well I'm reticent to take issue with a 'Telecomms Specialist' on the subject of DACS. But I have read of a number of cases where Internet users have noticed a significant drop in modem connect speed (to 33,000 bps or worse) after their line had been DACSed. Those few that were able, with considerable difficulty, to persuade BT to remove the DACS unit, noticed a considerable improvement and their connect speeds restored to their previous values.
On the subject of extensions, I'm also aware that disconnecting them can help, but I've found that in my own case it makes absolutely no difference. (I have four extensions) Perhaps I should also mention, ever so modestly, that the extensions were installed by yours truly!
