Check with the manufacturer of your phone system.  They can provide a
card that will do the conversion for you.

Adtran doesn't have anything specific for this that i can find -
remember, i need the DTMF tones passed _after_ off-hook.  the best i
can think to do with adtran is to put some sort of device before the t-1
switch and convert it to analog there, but thats no cheap adaptor and
also
assumes advanced knowledge of which channel's the incoming call is
coming
in on which i don't know that I have or who to talk to at telco to even
ask.  it also complicates things if i wanted dial-in and dial-out on
it.
