I have not done so but asterisk should handle this. See zaptel.conf 
file for configuration notes.

for a T400p card, configure zaptel.conf
for 1st span
  span=1,1,0,d4,ami
for 2nd span
  span=1,2,0,d4,ami

assuming
you want to get your clock from the first T1 if available or 2nd T1 is 
1st is not available.
the T1 is terminated close to your asterisk system (less than 133 feet) 
framing is d4 (SuperFrame or sf)
line coding is ami

also in zaptel.conf
  e&m=1-48

in zapata.conf you would set the wink information
  signalling=em_w
see zapata.conf notes in file for more information
