A method and system thereof for maintaining and broadcasting frame numbers in a digital communication system. The system monitors a frame number controller through a central controlling unit. The frame number controller maintains the frame numbers required by the system, as well as broadcasts the frame number for the subsequent data frame to each frame number receiver in the operational components. Each frame number receiver generates a frame boundary signal when a complete frame number is received from the frame number controller, and notifies the corresponding operational component to start using the frame number just received. The operational component can also determine if unfinished work according to the frame boundary signal exists, and report the error to the system. The aim is to provide a simple mechanism to maintain the synchronization of the system, and utilizes the serial port to transmit information related to the new frame number.
