Hi Geoff,
Good point of clarification.
I was not directly involved in that effort. At the time I was working
on
802.4 (rf modems,CATV,etc) but I know a number of the folks who worked on
it
and actually have an original copy of the massive binder full of work
done
by Bob Conte et al. It was an impressive effort and I think we are
looking
at something similar here.
I wasn't really involved in it. I was working on fiber a the time. Pat
was in the middle of it. The guy who did the major work in the field was
Don Johnson of NCR at the time. I have seen him recently in wireless
meetings so he might possibly be available to provide war stories.
It was HARD!
Geoff
Regards,
Dan
