Anyway, all of
this doesn't further the raised floor discussion much,

the way that computing evolved in the UK, if GPO convention was to

overhead then doubtless this was carried over into a lot of computer
installations; the US and other countries may have taken a much
different route though, with raised floors adopted much earlier)
(which raises an incidental question; were
Strowger exchanges in
non-UK
countries typically wired overhead or below-floor?)
A friend who has spent a lot of time working in US COs says:
The only below-floor wiring I've *ever* seen in a CO was in the
7th
floor computer room, which was managed by the company from whom
Bell
bought the computer. Everything else is overhead, always always
always.
My old employer's facility in Laurel, MD was in a building that
formerly housed a Bell CO. There were channels in the floor with
round holes every few feet (presumably they used fish tape to get
stuff around) and the facility's wiring was all done through there.
Just FYI.
