set-number: The number of the channel set formed by timeslot bundling on the 
interface. It ranges from 0 to 23.

timeslot-list list: Specifies timeslots to be bundled. The list argument is timeslot 
numbers, in the range of 1 to 24. You may specify a single timeslot by specifying a 
number, a range of timeslots by specifying a range in the form of 
number1-number2, or several discrete timeslots by specifying number1, 
number2-number3.

speed { 56k | 64k }: Speed of the timeslot bundle (the channel set) in kbps. If 56k 
is selected, the timeslots is bundled into N 

× 56 kbps bundles. If 64k, the default, 

is selected, the timeslots is bundled into N 

× 64 kbps bundles.

Use the channel-set command to bundle timeslots on the CT1/PRI interface into 
a channel set.

Use the undo channel-set command to remove a specified or all channel sets.

By default, no timeslots are bundled into channel sets.

A CT1/PRI interface is physically divided into 24 timeslots numbered 1 through 24. 
In actual applications, all the timeslots can be bundled into multiple channel sets. 
For each channel set, the system automatically creates a serial interface logically 
equivalent to a synchronous serial interface.

The serial interface is named in the form of serial interface-number:set-number, 
where interface-number starts from the maximum serial interface number plus 1, 
and set-number represents the number of the channel set.

Only one timeslot bundling mode is supported on a CT1/PRI interface at a time. In 
other words, you cannot use this command together with the pri-set command.

CT1/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 CT1/PRI interface.
