Interleave Depth

[#1]

To assist me in improving my knowledge can someone please explain the InterleaveDepth figure in my stats below? From my limited understanding of it, it normally goes up 1, 2, 4, 8, 16, 32 etc.... so what does 841 mean? If I'm wrong in my assumption then I apologise in advance.

Anyone?

InterleaveDepth is now 1 which I know means off ie Fastpath but I'm still curious what the 841 meant?

This explains better than I ever could

The interleaving depths up to 64 are for ADSL.
VDSL2 can use much greater interleaving depths, the maximum interleaving depth is 3072 (for profile 17a).
