216 CHAPTER 13: FUNDAMENTAL CT1/PRI INTERFACE CONFIGURATION COMMANDS
Parameter 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.
Description 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.
Example # Bundle timeslots 1, 2, 5, 10 through 15, and 18 into channel set 0 on CT1/PRI
interface T1 2/0.

[Sysname] controller t1 2/0

Parameter master: Adopts the internal clock as the clock source.
slave: Adopts the line clock as the clock source.
Description Use the
clock command to configure clock source for the CT1/PRI interface.
