Abstract

Abstract of the Disclosure:

In an earth station having a particular address and comprising a terminal and a transmitting section for transmitting a transmission data signal including an address signal representative of the particular address towards a satellite through a single communication channel, a receiving section receives a reception data signal comprising the transmission data signal which is sent from the satellite through the single communication channel. By detecting the particular address, a decision circuit decides whether or not the receiving section correctly receives the reception data signal within a predetermined time interval after the transmitting section starts transmission of the transmission data signal. When the receiving section does not correctly receive the reception data signal, the transmitting section stops the transmission of the transmission data signal and an alarm signal is supplied to the terminal. Alternatively, the transmission data signal may include another address signal representative of another address of another earth station.
