672CHAPTER 45: CPOS INTERFACE CONFIGURATION COMMANDS

Before you can configure a CPOS physical interface, you must enter its CPOS interface view.

Example # Enter the interface view of CPOS 1/0.

<Sysname> system-view [Sysname] controller cpos 1/0 [Sysname-Cpos1/0]

crc

Syntax	crc { 16 32 none }
	undo crc
View	Synchronizing serial interface view
Parameter	16: Sets the length of the CRC word to 16 bits.
	32: Sets the length of the CRC word to 32 bits.
	None: Disables CRC.
Description	Use the crc command to set the CRC word length for a synchronizing serial
	interface formed by CPOS interfaces.
	Use the undo crc command to restore the default.
	The CRC word length for a synchronizing serial interface formed by CPOS
	interfaces defaults to 16 bits.
Example	# Set the CRC word length to 16 bits for CPOS interface 1/0.
	<Sysname> system-view
	[Sysname] controller cpos 1/0
	[Sysname-Cpos1/0] e1 3 channel-set 1 timeslot-list 1-31
	[Sysname-Cpos1/0] quit
	[Sysname] interface serial 1/0/3:1
	[Sysname-Serial1/0/3:1] crc 16
