>>> ISDN falls into 2 flavors 1) the original (true) ISDN adapters for PCI and NuBus. Foresight, Leonardo, and Planet. They support the traditional protocols" HDLC, X.25, x.75 and so on. They all work with each other. They support up to 128K. 2) the asynchronous ISDN adapters - these were designed for low - cost internet access mainly. BitSurfr, 3Com Access, and the GeoPort adapter. These devices support V.120 and (some) PPP. Some of these work with each other, but its best to stick with the same brand and model. These support up to 56K. <<< In item 2, are you referring to the Sagem-Planet ISDN Geoport Internet Adapter? This device, which apparently has been developed in cooperation with Apple, is becoming rapidly very popular in The Netherlands. It supports up to 128k and from tests with several of our SpiderNet users it appeared just as convenient and fast as the original internal Planet card.
