on the advice of others here, I ebayed some "external" cat5e cable for

stranded iso 11801 100mhz"

Well, there are things called search engines, which quickly reveal
that ISO 11801 is about wiring for premises, so presumably inside
http://www.iso.org/iso/catalogue_detail.htm?csnumber=36491.

mmm that link appears to merely offer the opportunity to purchase a
copy of the ISO standard for 200 odd swiss francs?

More usefully, though still confusingly, when I searched (before
asking on here), the first hit was Wikipedia which says:-
"The standard was designed for use within commercial premises that may
consist of either a single building or of multiple buildings on a
campus."

(campus n. , pl. , -puses . The grounds of a school, college,
university, or hospital. )

so am I to assume that ordinary Cat5 can be used to connect one campus
building to another? or that ISO 11801 is a red herring?
