Indeed.A basic fibre service used to cost arond 3 grand isntall..what
you put over t was up to you.
One of the cheaper ways of getting a leased line was to buy ISDN30, get
fibre installed for free, cancel the ISDN and order a 2Mbps leased line
"have you got fibre installed? You have! well that's easy, sir"
All due to disparate marketing policies on telephone traffic versius
data traffic.
