MODULATED ANALOG SIGNAL TRANSMISSION EQUIPMENT AND TIS SYNCHRONISM RECOVERY METHOD

摘要

PURPOSE:To provide the modulated analog signal transmission device and its synchronism recovery method which can converge the diverged synchronism of a receiving modem as to high-speed analog modulated signal transmission of >=14.4kbps. CONSTITUTION:A receiving modem 11 sends out a fault report 14 to a transmitting modem 10 in a faulty state due to synchronism divergence during the transmission of an analog modulated signal in a network consisting of the transmitting modem 10 and receiving modems 11 of N (N: natural number such as 1, 2, 3...) stations and a signal transmission line 12 between the both. The transmitting modem 10 sends out a training signal for synchronization to the receiving modem in response to the fault report 14 to make synchronism recovery.
