All ISDN adapters does, because you'll get a final speed on 128000 then you
are bundling the 2 channels, and it's more than the serial port can handle,
but Zyxel OMNI.NET+ support at DTE speed on 460800 afair, but i doesn't
have a high speed serial port in my machine.

The speed can be usefull even if you are not bundling, because the V42B
compression make it possible to make a 4:1 compression, then you have a DTE
speed on 64000 * 4 = 256kps.
