208CHAPTER 12: FUNDAMENTAL CE1/PRI INTERFACE CONFIGURATION COMMANDS

n

Example

■The support of this command varies with device model.

■This command applies to CT1/PRI interfaces and CE1/PRI interfaces only.

#restart channel serial 2/0:0 that has been shut down due to error packets diffusion.

<Sysname> system-view

[Sysname] error-diffusion restraint restart-channel serial 2/0:0

frame-format (CE1/PRI interface view)

Syntax	frame-format { crc4 no-crc4 }
	undo frame-format
View	CE1/PRI interface view
Parameter	crc4: Sets framing format to CRC4.
	no-crc4: Sets framing format to no-CRC4.
Description	Use the frame-formatcommand to set the framing format on the CE1 interface.
	Use the undo frame-formatcommand to restore the default, that is, no-CRC4.
	A CE1/PRI interface in CE1 mode supports both CRC4 and no-CRC4 framing
	formats, where CRC4 supports four-bit CRC on physical frames while no-CRC4
	does not.
Example	# Set the framing format on interface E1 2/0 to CRC4.
	<Sysname> system-view
	[Sysname] controller e1 2/0
	[Sysname-E1 2/0] frame-format crc4

idlecode (CE1/PRI interface view)

Syntax	idlecode { 7e ff }
	undo idlecode
View	CE1/PRI interface view
Parameter	7e: Sets line idle code to 0x7e.
	ff: Sets line idle code to 0xff.
Description	Use the idlecode command to set the line idle code on the CE1/PRI interface.
	Two types of line idle code are available: 0x7E and 0xFF.
