I just got my copies of IPC-2221 and 2222.  I'm trying to read it
(ARGH!) and understand a little of it.  The table on page 5 and 6
seems like good information for me to know but I'm hung up early in
the game.  Would someone please define "lateral crosstalk" and
"vertical crosstalk"?  I asked our EMC guy but he isn't familiar with
those terms.  My guess would be that lateral deals with noise created
by traces on the same side (layer) of a board and vertical is noise
created by traces on different layers.  Am I close?  This isn't
defined in IPC-T-50.

Thanks again!  :-)
