DC RECOVERY CHANGEOVER TIMING SYSTEM FOR TELE-TERMINAL SYSTEM

摘要

PURPOSE:To recover a data packet received through burst communication with excellent reliability accurately by controlling the operating timing of a DC recovery circuit based on the transmission timing of a polling packet. CONSTITUTION:Since the terminal equipment starts burst communication of a data packet after a prescribed time after the reception of a polling packet, a control section 3 of a tele-terminal controls the operating timing of the DC recovery circuit 23 based on the transmission timing of the polling packet. That is, the detection of a DC component of the received data packet and the operating timing of the storage of the detected DC component are controlled in the DC recovery circuit 23 so as to specify the operating timing accurately. Then the data packet received through burst communication from the terminal equipment is always received and recovered accurately with excellent reliability.
