That's only since the ISDN standardizing people were too stupid to also supply a non-guaranteed, statistical service (like Ethernet). This would have been totally sufficient for IP, but that's what you get when telephone people design a standard for data communication: they don't have a clue about it, and a service that's not ``reliable'' in its data transfer guarantees simply cannot happen in their brains. There are infact packet-switched services available with ISDN, but they are rarely used, and IIRC can only be used to tunnel packets to/from the obsolete X.25 network. -- 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. ;-)
