  • Control and monitoring telecommunication system and method of setting a modulation method
    Patent number: 7570748
    Abstract: Using a network in which one master station modem 105 and multiple slave station modem 106, 107, 108 are physically connected by rudder connection or bus connection with a telecommunication line 121, the measurement result of the S/N ratio between the master station and slave stations is once collected in the master station at the initialization stage, pairs of the modulation method, by which all modems can demodulate at high probability, and transmission voltage are calculated based on this data, and the calculation is transmitted to all slave stations; and at a normal transmission stage, information regarding the coordination and control of the network is transmitted in accordance with this setting. Thus, one-to-multi communication is realized, guaranteeing an access right.
