But your argument doesn't make much sense: switch-to-switch interconnections are already 90 % digitalized anyway, thus benefiting from this regardless of whether the customer uses a digital or an analog line. So it's indeed only the fanout technology that changes. A change from an analog to an ISDN line takes some two hours. > There > really was no need to push ISDN in the US as there are alternate cheap > technologies available. But no _integrated_ technology. They've got better technology for raw IP transfers (and ISDN really sucks for this), but you can't use the same line for a phone call then. I don't argue that most of the US tariffs are cheaper; only long- distance calls on public phones are surprisingly expensive. :) -- cheers, J"org joerg_wunsch@uriah.heep.sax.de -- http://www.sax.de/~joerg/ -- NIC: JW11-RIPE Never trust an operating system you don't have sources for. ;-)
