11.1.1 Telegram Quality
The following applies to all time sources: Each read-in and valid time packet increases
the value by 10. Accordingly, this value decreases by 10 for each missing or invalid time
packet.
Telegram quality (resp. sync. quality) is available for all external time sources.
Notice:
An ideal figure for telegram quality is 100. All other figures greater than 60 are
however adequate for reliable synchronization.

For all time sources: With every read in of the seconds mark, this figure increases by 1.
This figure reduces accordingly by 1 for every missing seconds mark.
Signal quality (resp. valid time telegrams) is available from the following time sources:
DCF, MSF, GPS4500, GPS-TSIP and GPS-NMEA.
