218 CHAPTER 13: FUNDAMENTAL CT1/PRI INTERFACE CONFIGURATION COMMANDS
<Sysname> system-view
[Sysname] controller t1 2/0
[Sysname-T1 2/0]
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: Disables CRC.
Description Use the
crc command to configure CRC mode for a synchronous serial interface
formed on a CE1/PRI interface.
Use the
undo crc command to restore the default, that is, 16-bit CRC.
Example # Apply 32-bit CRC to a serial interface formed on interface CT1 interface 2/0.
<Sysname> system-view
[Sysname] controller t1 2/0
[Sysname-T1 2/0] channel-set 1 timeslot-list 2-6
[Sysname-T1 2/0] quit
[Sysname] interface serial 2/0:1
[Sysname-Serial2/0:1] crc 32
data-coding (CT1/PRI interface view)
Syntax data-coding { inverted | normal }
undo data-coding
View CT1/PRI interface view
Parameter inverted: Enables user data inversion.
normal: Disables user data inversion.
Description Use the
data-coding normal command to disable user data inversion on the
CT1/PRI interface.
Use the
data-coding inverted command to enable user data inversion on the
CT1/PRI interface.
