The clock mode for a CT3 interface is slave.
Views
CT3 interface view
Predefined user roles

Parameters
master: Sets the clock mode to master.
slave: Sets the clock mode to slave.
Usage guidelines
When the clock mode of a CT3 interface is master, it uses the internal clock source.
When the clock mode of a CT3 interface is slave, it uses the line clock source.
When connected to a transmission device, the CT3 interface must use the slave clock. The clock provided
by the transmission device is more precise.
When two CT3 interfaces are directly connected, you must configure the two ends with different clock
modes.

# Set the clock mode to master for T3 2/4/0.
