We just went through this here.  The Adtran T3SU-300 with two DSX-1 
cards will do exactly what you want to do.  Each DSX card peels off 4 
DS-1s, leaving you with approximately 33 Mbps of bandwidth on the 
built-in HSSI port.

Only drawback is that you need HSSI cards in the routers on both ends to 
  handle the IP part.

If you need any details or help with the setup, give me a shout.  Been 
there, done that.
