Title: Data transmission method
Inventor: MURAKAMI HARUHIKO
IPC: H04M11/00
Filed: 1993-06-30
Abstract: PURPOSE:To send lots of data in a short period by sending an MF signal not intermittently but continuously for data transmission when the MF signal is sent to a telephone line for data transmission. CONSTITUTION:An MF signal for data is sent not intermittently but continuously. Data are outputted from a signal decision circuit 5 at a management center side in real time. Thus, when a stop time for intermittent transmission is equal to transmission time of one data, the data transmission quantity is doubled. Since the time required to detect the MF signal is enough to be short, the time for measuring the signal amplitude executed for each reception of the MF signal is reduced by automatic gain control of, e.g. an operational amplifier 8. Thus, data transmission time is reduced and then the data transmission quantity is more increased.
