indeed. This is updated in the document.

Apparently, the figure had number 7-11 in version I11 of the PHY spec, and
is figure number 14 in version I12 of the spec. I updated the number to 14,
to reflect the number in the more recent spec. I also added references to
the DOCSIS MULPI and PHY specification version numbers, to avoid confusion
in the future.
