Modulation
The carrier amplitude is switched off at the
beginning of each second for a period of 100 ms
(binary zero) or 200 ms (binary one).
Time-Code Format
The time-code format consists of 1-minute time
frames. A time frame contains BCD coded
information of year, month, calendar day, day of
the week, hours and minutes. At the switch-over
to the next time frame, the carrier amplitude is
reduced for a period of 500 ms.
The presence of the fast code during the first
500 ms at the beginning of the minute is not
guaranteed. The transmission rate is 100 bit/s and
the code contains information of hour, minute, day
and month.
