I am currently using a Pace UltraLink ISDN TA on my SA Risc PC with 
great success. As my ISP is Demon, I can only use one channel at present,
but that might change... ;-) Strangely, I had a problem connecting
to Demon for a while (only one call in 5, on average, connected
successfully), but when I changed my access number to the new 'Green'
ROMP, all the problems disappeared. There is a driver file in the
ANT suite for the Ultralink, but I have modified it to force
communication between the Risc PC and the TA to 115200 baud
(setting S114 to the value 115). The entire initialisation string
is therefore:

AT&O7 S114=115 S124=0 S95=255

in case you need help setting up SlipDial/Socketeer. If you wanted
to force 230400 baud (if you're able to bond the two ISDN channels),
set S114 to 230 instead of 115.

One idiosyncrasy: when my software sends the ATD command to the
TA, it almost always responds immediately with a 'NO DIAL TONE'
error, so I have set my software to redial every second: the
second ATD always works! I can't see a way of making the TA
wait a little longer for the dial tone before trying to dial.

Good luck!
