To provide an ATM transfer system of data packets wherein transmission efficiency is improved by reducing useless occupation of the ATM network capacity; each of telephones (A and B) sends out a first and a second data packet destined to each of telephones (C and D), a network terminal (10) sends out an ATM cell multi-loaded with the first and the second data packet, the transmitter-side exchange (1) duplicates the ATM cell into a first and a second duplicated ATM cell, a receiver-side exchange (2) extracts only the first data packet and sends out a first new ATM cell loaded only with the first data packet while another receiver-side exchange (3) sends out a second new ATM cell loaded only with the second data packet in the same way, and each of network terminals (20 and 30) processes each of the first and the second new ATM cell into each of the first and second data packet to be sent to each of the telephones (C and D).
