208 CHAPTER 12: FUNDAMENTAL CE1/PRI INTERFACE CONFIGURATION COMMANDS
n
■ The support of this command varies with device model.
■ This command applies to CT1/PRI interfaces and CE1/PRI interfaces only.
Example # 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-format command to set the framing format on the CE1 interface.
Use the undo frame-format command 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.
