You should be aware that the XCVR2450 is a *half duplex* 
daughtercard--the hardware is physically incapable of receiving and
  transmitting *at the same time*, although it's perfectly capable of 
half-duplex operations, which can certainly happen on a single
  USRP2 with suitable Gnu Radio flow-graph behind it.
