The data bit has a length of 48 clocks based on a 13 MHM clock. In a personal communication system configured to configure one time slot with 156.25 bits, a reference clock of 13 MHz is generated to generate a bit synchronization signal based on the reference clock and the frame start signal, and then based on the bit synchronization signal and the reference clock. This generates a time slot synchronization signal and a 149-bit clock signal. Next, the current time slot number is calculated by counting the time slot synchronization signal, and the time slot number corresponding to the allocated time slot of the first time slot of each frame is calculated based on the time slot number and the independent control channel number assigned from the outside. The strobe signal is output. The frame synchronization signal is generated based on the time slot number, the frame synchronization signal is counted, the frame number is calculated, and the data for the independent control channel number is calculated based on the independent control channel number assigned through the base station. The frame number data outputted from the frame number counting means compares the data and outputs a high level signal when the data is matched, and independently controls the uplink of the personal communication terminal based on the output signal and the 149 bit clock signal. Generates an interrupt signal for the channel.
