Use the channel-set command to bundle timeslots on the CE1/PRI interface into 
a channel-set.

Use the undo channel-set command to restore the default.

By default, no timeslots are bundled into channel sets.

A CE1/PRI interface in CE1/PRI mode is physically divided into 32 timeslots 
numbered 0 through 31.

In actual applications, all the timeslots except timeslot 0 can be bundled into 
multiple channel sets. For each channel set, the system automatically creates a 
serial interface which is logically equivalent to a synchronous serial interface.

The serial interface is numbered in the form of serial 
interface-number:set-number, where, interface-number is the number of the 
CE1/PRI interface, and set-number is the number of the channel set.

Only one timeslot bundling mode can be supported on a CE1/PRI interface at a 
time. In other words, this command cannot be used together with the pri-set 
command.

CE1/PRI interface view

master: Adopts the internal clock as the clock source.

slave: Adopts the line clock as the clock source.

Use the clock command to configure clock source for the CE1/PRI interface.

Use the undo clock command to restore the default clock source, that is, line 
clock.
