216CHAPTER 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-listlist: 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-setcommand to bundle timeslots on the CT1/PRI interface into a channel set.

Use the undo channel-setcommand 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-numberstarts from the maximum serial interface number plus 1, and set-numberrepresents 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-setcommand.

Example # Bundle timeslots 1, 2, 5, 10 through 15, and 18 into channel set 0 on CT1/PRI interface T1 2/0.

clock (CT1/PRI interface view)

Syntax	clock { master slave }
	undo clock
View	CT1/PRI interface view
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.
