0. STOP

Force to manually trigger the holdover (START) or to
expire it (STOP) without waiting the expiration timer.

HO in between timing source
Using the source rank the HO can be placed between two timing sources. For example,
the user can use WR as primary timing source, HO as secondary and PTP 8265.1 as third
one. This means that if WR fails, the device will enter in HO until expiration and finally
switch to PTP that might provide better accuracy than an expired HO.
