With a line of that length (like less then 4 km or so), it would be quite possible to run at a much higher speed. For example, the ISDN U-interface can be run at either 80kb or 160kb (full duplex over 1 pair, even) over distances like that with little or no problems. Sometime soon, I am going to be performing some experiments with this type of interface running at 160kb on a loop that is aprox 1.5 km long. I think that this type of setup could lend itself to be kind of a happy medium between a dial-up line (even at 9.6kb) and a VERY MEGA-EXPENSIVE dds line, which I dont think that any of us could personally afford. If anyone has any interest in these types of experiments, please contact me. P.S. My mail link was down today, so I dialed up into BU. I can normally be reached at DIXON@OZ.AI.MIT.EDU or more specifically JIM%EGGO%LAMBDA@OZ.AI.MIT.EDU Happy Networking... Jim Dixon..
