R2511-HP MSR Router Series Interface Command Reference(V5)

142
Parameters
number: CT1/PRI interface number.
Examples
# Enter the view of interface T1 2/0.
<Sysname> system-view
[Sysname] controller t1 2/0
[Sysname-T1 2/0]
crc
Use crc to configure CRC mode for a synchronous serial interface formed on a CT1/PRI interface.
Use undo crc to restore the default.
Syntax
crc { 16 | 32 | none }
undo crc
Default
The CRC mode for a synchronous serial interface formed on a CT1/PRI interface is 16-bit CRC.
Views
Synchronous serial interface view
Default command level
2: System level
Parameters
16: Adopts 16-bit CRC.
32: Adopts 32-bit CRC.
none: Disables CRC.
Examples
# 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)
Use data-coding inverted to enable user data inversion on the CT1/PRI interface.
Use data-coding normal to disable user data inversion on the CT1/PRI interface.
Use undo data-coding to restore the default.
Syntax
data-coding { inverted | normal }
