Parameters
t3-number: Number of a T3 channel on the current CPOS interface, in the range of 1 to 3.
master: Sets the clock mode to master.
slave: Sets the clock mode to slave.
Usage guidelines
You can configure different clock modes for different T3 channels depending on the device each T3
channel is connected to. For example, when a T3 channel is connected to a SONET/SDH device, set its
clock mode to slave. When two devices are directly connected through an optical fiber, set different clock
modes for the two ends.
The clock mode of a T3 channel of a CPOS interface is independent of that of any other T3 channel of
the CPOS interface.
Configure the clock mode of a T3 channel the same as the global clock mode.
Examples
# Configure the clock mode of the T3 channel 1 of CPOS 2/0/0 as master.
