202CHAPTER 12: FUNDAMENTAL CE1/PRI INTERFACE CONFIGURATION COMMANDS

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

Use the undo channel-setcommand 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-numberis the number of the CE1/PRI interface, and set-numberis 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-setcommand.

Example # Bundle timeslots 1, 2, 5, 10 through 15, and 18 on CE1/PRI interface E1 2/0 into channel set 0.

[Sysname] controller e1 2/0

# Make the same configuration on the CE1/PRI interface on the remote router.

clock (CE1/PRI interface view)

Syntax	clock { master slave }
	undo clock
View	CE1/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 CE1/PRI interface.
	Use the undo clock command to restore the default clock source, that is, line
	clock.
