You can connect the modems back to back using the 1and 2, 4 and 5 wire pairing. That is you should connect the Transmit to recieve pair and recieve to trasmit pair in the 4 wire in the G.703 between the modems to simulate a leased line. Mostly between a V.35 and G.703 it will be a 2 wire and you can connect , as there is not Transmit or Receive pair in it.


V.35 <----> G.703 <----------------> G.703 <-----------> V.35

2 wire 4 wire 2 wire


Also in case if you have only one pair of V.35 and G.703 , you can do a short circuit of Tx to Rx and Rx to Tx in the G.703 side. Set one of the modem to Master and the other as Slave or receive clock. And you can try the DTE side and Network side loop to test the modems.
