In a switching system, a data compression/transmission and restoration method performed using an IPC (inter processor communication) checks whether received original data is repeated, provides a pertinent signal to the checked data, transmitting the signal, and restores the signal in a main processor. Data compression efficiency is improved by checking whether one byte of received data is repeated, providing a different signal according to the check result, and transmitting the resulting information through the IPC. In addition, load on the overall switching system is reduced in terms of data compression time and restoration time.
