Remember the way analog modems achieve higher rates includes compression which is equally applicable to ISDN. So if compression can double a 28.8 to 56kb/s then the same compression can double ISDN's 128kb/s to 256kb/s and so on. ISDN may not have a big edge but its a pretty decent one for now. The problem with analog modems is they fall back in speed when they encounter a bad connection in the voice network. This is actually pretty prevalent ( lots of back to back channel banks ( lots of A/D and D/A conversions)). ISDN is always routed through the digital network with a pure digital connection and no chance of a weird analog problem and very low error rates. If a fast analog modem falls back to a lower speed then you can't count on them for fast connections always.
