IMPORTANT:
For successful communication, make sure the local end has the same timeslot bundling settings as the
remote end.
Examples
# Bundle timeslots 1 through 23 into a channel set on T1 channel 1.
<Sysname> system-view
[Sysname] controller cpos 2/4/0
[Sysname-Cpos2/4/0] t1 1 channel-set 1 timeslot-list 1-23
# Enter the view of the serial interface created for the channel set.

Parameters
t1-number: Specifies a T1 channel by its number on the CPOS interface. The value range for this
argument is 1 to 84.
master: Sets the clock mode to master.
slave: Sets the clock mode to slave.
Usage guidelines
The clock mode settings of the T1 channels on a CPOS interface are independent of one another.
Set the clock mode on a T1 channel depending on its connected device.
• If the connected device is a SONET/SDH device, enable the slave clock mode on the channel. The
SONET/SDH network clock is more precise than the clock provided by the device.
• If the T1 channel is directly connected to a router, make sure the T1 channel uses a different clock
mode than the peer end.
