MFT ports are Multi Function Trunks - they speak
several dialects of T1/E1, including voice.
As to back to back ATM, you can do a similiar thing
with standard serial ports. Its call ATM-DXI; see
http://www.cisco.com/univercd/cc/td/doc/product/software/ios113ed/113ed_cr/wan_c/wcatmser.htm
Its a bit lame, in that all your ATM-like commands are
prefaced with DXI, and with no ATM switch in the
middle, you have no ILMI, but you get PVC's.
