Menu: Time Service
The Time Service page is used to set up the additional time service parameters for
needed for a more specific configuration of the NTP and PTP IEEE1588 subsystem.
To enter the following sub menu press the „OK“ or right arrow button:
Menu: external NTP server
The default configuration of the timeserver consists of a local clock, which
represents the hardware clock of your LANTIME system and the GPS reference
clock. The local clock is only chosen as the NTP time reference after the GPS clock
lost its synchronization. The stratum level of this local clock is set to 12, this ensures
that clients recognize the switchover to the local clock and are able to eventually take
further actions. The local clock can be disabled if the timeserver should not answer
anymore when the reference clock is out of order.
Up to seven additional external NTP servers can be set up to provide a high grade of
redundancy for the internal reference clock. Via the front panel you can set up 4
external servers. Please use the WEB interface to set up more external servers.
