2.15.14 Host Disciplining

Host Disciplining allows an NTP input reference to discipline SecureSync's oscillator. This may
be utilized e.g., with SecureSync units that do not have a GPS receiver because they are oper
ated as Stratum 2 servers.
In general, it is advisable to enable Host Disciplining only if needed, and to use it only in
robust networks/NTP environments.
Note that Host Disciplining is NOT supported by SecureSync units equipped with a Rubidium
oscillator.
ON : When Host Disciplining is ON, the NTP reference is used to discipline
SecureSync's oscillator, thus providing more stable oscillator performance.
About system software updates:
When updating to System Software Version 5.4.5, Host Disciplining will fall to its
default setting. When updating to future System Software versions, the last setting will be
carried over to the new software.
In any case, after a system software update it is advisable to verify that Host Disciplining
is still enabled.
