My D side is 142m and E side 1667m and line length 248m
Your line length and D-Side are essentially the same thing.
It could be argued VDSL2 line length includes the tie cables, while the D-Side does not.
Your tie cables are not 106m.
Where do you come up with 142m for your D-Side?
Come to think of of, where did you pluck the 1667m E-Side figure? That's a very exact figure for a rough guess.
