Receiver clocks connected to the line receive a complete time message every second. The
2 main signals are transmitted on a modulated or DCLS version. The signal is modulated
only on card ‘B’. The output signal of card ‘T’ is a TTL signal. The modulated signal reaches
a peak of 2.2V. The TTL signal changes from 0V to 5V.
