Hi, Thanks for the reply.
This info was given by my ISP (orange) as I had experienced a broadband failure, apparently at my local exchange and a "lift and Shift" was carried out ( whatever that means) after a faulty connector repair failed to solve the problem. The lift and shift was carried out along with the "level 1 Modification. This ifo was given to orange by BT.
I am afraid that that is all the info I have. I just wondered what this entailed.
