Larry:
The IBT location is determined by the EC. It is in the vicinity of electrical meter, or service point.
In 'rehab' (service upgrade) the battle on occasion is 'who connects the telco/cable/etc grounds/bonds to the IBT'??
That was a battle in the begining, now most ECs will make the termination. It's basically "Good Luck" trying to get any of the LV guys to do it on rehab work.
