[over ISDN - J.] Because of the existing, well-defined negotiation protocol. Almost all router manufacturers went away from their home-grown, mutually incompatible ``IP over raw HDLC'' protocols. I don't know of any ISDN router that doesn't support PPP right now, but i know of router manufacturers who dropped (or intend to drop) their legacy ``raw HDLC'' options. They ended up reinwhenting the PPP wheel anyway, regarding IP address negotiation, LQR etc. Let alone compatibility to other peers. It's a often stated but unproven myth that PPP adds _much_ overhead. You end up with the same near 8 KB/s throughput per 64 Kbit/s channel nevertheless. -- 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. ;-)
