A next generation network system based on a time compression multiplex integrated service digital network technique (TCM ISDN) and a control method thereof. The system includes a synchronous clock generator for generating a transmit timing reference (TTR) reference clock to be used in a TCM ISDN and an xDSL, using a broadband clock provided through an asynchronous transfer mode (ATM) network; and a TCM ISDN subscriber processor for temporarily storing TCM ISDN data received from a public switched telephone network (PSTN), arranging a frame of the TCM ISDN data, synchronizing the TCM ISDN data to the TTR reference clock provided from the synchronous clock generator, and transmitting the synchronized TCM ISDN data to a TCM ISDN subscriber while, synchronizing the TCM ISDN data received from a TCM ISDN terminal, to the TTR reference clock input from the synchronous clock generator, temporarily storing the synchronized TCM ISDN data, and transmitting the stored TCM ISDN data to the PSTN.
