said by tschmidt:said by Ark:Perhaps if you are far from the VRAD, and there are still some of those little cross-connect boxes in the path, your 2nd/3rd pair don't make it all the way back to the VRAD, but around here, they seem to put a VRAD right next to every cross-connect box.
The problem is feeder cable size from cross connect box to customer. The whole ideal of using FTTC VRADs is to eliminate need to run fiber all the way to the customer. If they run out of copper pair and need to install more economic model falls apart.
This happened once before during the heyday of dialup modems. Lots of hard core data users opted for second phone line - causing local copper shortages in many locations.

And I would assume today the inverse is happening. The 2nd line is going away and probably very rapidly and those 2nd lines are still in there.
