
In case of loss of the master GPS, the master stratum increases on the basis of the
configurable parameters up to the maximum stratum. The slave follows, i.e. the
slave stratum is always 1 higher. The slave takes over the master role from a
configurable stratum value (if the status of the slave is better than that of the master)
and synchronizes to its own GPS. The previous master becomes the slave. This
distribution of roles remains until the new master loses GPS synchronization.

In the case of a loss of the master, the slave assumes the master function.

If the former master is working again, it assumes the actual time of the current
master and remains in slave mode.

In the case of a fiber optic connection loss, the slave checks the status of the master
over the network and remains in slave mode as long as the master is accessible and
is working normally. If the master is no longer accessible or has a worse status, the
slave assumes the master function.
NTP
The NTP clients select the server with the lower stratum.
DCF77 coded (fiber optic output)
No redundancy
2 LAN Mode
The two redundant DTS 4138 are not located in the same network. The role decision
(master, slave) takes place exclusively via opt. link.
RTC:
RTC is to be deactivated for the redundant mode.
