But that's not all about it. For an ISDN connection you also need
a time slice wide enough for 64Kbits/s on the backbone of the providers
switching device. When you got a dialup connection and not a permanent one
you're on a system where the number of available time slices is less
than no_of_customers/2, guess why there is a price difference between
a dialup connection and a permanent one. So if you use up a time slice
without actually using it and anyone else does the same, you force
the provider to upgrade their network switching devices. Someone has
to pay for that, they won't do that for nothing. Also with connect times
< 1 sec there is no reason to keep the line alive 24 hours a day.

In providing bandwith on the backbone and no_of_customers/2 is way more
expensive than 25% of no_of_customers, or whatever their analysis about
usage of the available bandwith found appropriate. The next thing you
demand is that your ISP guarantees you an exclusive bandwith of
64Kbits/s 24x7 to everywhere, for $20 per month of course <g>

They all will gladly sell you a permanent line which you have connected
24x7, no prob, but I guess you don't like to pay for that. Ah well,
here in Germany it's not a topic at all because the single provider here
will charge your socks off for using a dialup ISDN connection 24x7.
That's several times more expensive here than a permanent connection,
intentionaly I would say. With enough people with the 'right'
attitude it sure is possible to make it like that worldwide <g>
