Parameters
t1-number: Number of a T1 channel on the CPOS interface, in the range of 1 to 84.
master: Sets the clock mode of the T1 channel to master.
slave: Sets the clock mode of the T1 channel to slave.
Usage guidelines
T1 channels on the same CPOS physical interface can use different clock modes, depending on
connected devices. For example, when connected to a SONET/SDH device, a T1 channel must use the
slave clock mode. When directly connected to another device through an optical fiber, the T1 channel
must use different clock modes at the two ends.
Different T1 channels of the same CPOS physical interface are independent of one another in terms of
clock mode.
Examples
# Set the clock mode of T1 channel 1 to master.
<Sysname> system-view
[Sysname] controller cpos 2/0/0
[Sysname-Cpos2/0/0] t1 1 set clock master
