Description
The clock node synchronizes its time to the master reference time source.
PTP assigns a time table to the clock node. A clock node with time class 6
cannot become a member clock of any other clocks in the domain.
The former time class is 6. The clock node cannot synchronize its time to a
time source. It enters the reappointment mode and meets the reappointment
conditions. PTP assigns a time table to the clock node. A clock node with
time class 7 cannot become a member clock of any other clocks in the
domain.
The clock node synchronizes its time to a time source. ARB assigns a time
table to the clock node. A clock node with time class 13 cannot become a
member clock of any other clocks in the domain.
The former time class is 13. The clock node cannot synchronize its time to a
time source. It enters the reappointment mode and meets the reappointment
conditions. ARB assigns a time table to the clock node. A clock node with
time class 14 cannot become a member clock of any other clocks in the
domain.
The clock node with time class 7 becomes optional clock A because it does
not meet the reappointment conditions. A clock node with time class 52
cannot become a member clock of any other clocks in the domain.
The clock node with time class 14 becomes optional clock A because it does
not meet the reappointment conditions. A clock node with time class 58
cannot become a member clock of any other clocks in the domain.
The clock node with time class 7 becomes optional clock B because it does
not meet the reappointment conditions. A clock node with time class 187 can
become a member clock of another clock in the domain.
The clock node with time class 14 becomes optional clock B because it does
not meet the reappointment conditions. A clock node with time class 193 can
become a member clock of another clock in the domain.
