Example # Use the internal clock as the clock source on CT3 interface T3 2/0.

<Sysname> system-view

[Sysname] interface t3 2/0

[Sysname-T3 2/0] clock master

controller t3

Syntax controller t3 interface-number

View System view

Parameter interface-number: CT3 interface number.

Description Use the controller t3 command to enter CT3 interface view.

crc

Syntax	crc { 16 32 none }
	undo crc
View	Synchronous serial interface view
Parameter	16: Adopts 16-bit CRC.
	32: Adopts 32-bit CRC.
	none: Adopts no CRC.
Description	Use the crc command to configure CRC mode for the serial interface formed on
	CT3 interfaces.
	Use the undo crc command to restore the default, that is, 16-bit CRC.
	These two commands apply to serial interfaces formed on T3 channels, T1
	channels, and the interfaces formed by binding slots of T1 channels.

Related command: t1 channel-set,t1 unframed, using (CT3 interface view).
