This might not be what you were after, but there is a hardware solution to
this.  It involves T1 circuit emulation cards (WAI-T1C-4RJ48) for a
LightStream 1010 ATM switch at the edges, which allow the T1s to be carried
in CBR PVCs through the ATM cloud.  I have 3 of those cards, which I bought &
tested a few years ago but never deployed.  I also have several 1010 chassis
& OC-3 cards which I no longer need & could probably be persuaded to part
with.  Let me know if you're interested.  If this isn't applicable to your
situation, then never mind.
