Once upon a time Christopher Masto shaped the electrons to say...
>Courier I-modem (their top-of-the line ISDN TA) hangs up before
>establishing a 56k data-over-voice ISDN connection to the PM3. It
>seem not to like the PM3's attempt to answer it as an analog call, and
>drops the instant the initial v.8bis tone is heard.

WHOA! If you are hearing v.8bis then the PM-3 is NOT doing DOSBS, it
sees it as a modem. Which means the USR is doing something wrong. If
it really were an ISDN DOSBS call you would never hear any modem tones,
period. The PM would connect it to the HDLC controller. The only time
you get modem tones is when the PM has tried HDLC and it just wasn't
there - so it hands it to a modem. I know this works, no question.
