The transmission of the End sequence by the transmitting modem is started as soon as the data message from the transmitting DTE includes an uninterrupted sequence of bits of the same polarity, the End sequence being completed by modem with bits of the same polarity until the predetermined duration, after a request signal for transmitting from the transmitting DTE has turned off.
