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 switched off for a period of 500 ms.
The prescence of the fast code during the first 500 ms at
the beginning of the minute is not guaranteed. The trans-
mission rate is 100 bits/s and the code contains
information of hour, minute, day and month.
