Some devices in the reference topology strategically include the holdover option (HO)
to ensure continuous operation even if not locked to any timing sources. This option is
automatically enabled if detected and the provided presets can be used without any
modifications.
5.2.3 Timing source info
Each timing source shares a common set of values processed by the strategy in order to decide
how to discipline the virtual clock of the device.
By clicking on the tabs
Timing > General
the user will be able to quickly get an overview of the
state of all timing sources. Figure shows the parameters related to the primary (#1) timing
source.
