Sorry but isn't this wrong?

The whole point about ISDN is that its a digital transmission network
therefore the conventional MODEM-PSTN-MODEM setup is useless because you
don't need to convert to analouge, you just send the straight digital data
stream down the line.  

The TA (Terminal adapter) connects your computer to the ISDN line at a very

fast data rate, upto 128Kbaud per sec if using X25 and both data channels on
ISDN 2! It also dials the number and sets the line up (using the D channel
I believe).  Therefor to use ISDN you need a suitable TA card to link
computer to ISDN and a software, like ISDN manager on the Mac, to control
said TA.  Your comms s/w must also support the ISDN card.  

I may be wrong but I didn't think there was any s/w on the Acorn that could
do this, I hope I'm wrong!
