3Com MSR 30, MSR 50 controller t3

268 CHAPTER 17: FUNDAMENTAL CT3 INTERFACE CONFIGURATION COMMANDS
Example # Use the internal clock as the clock source on CT3 interface T3 2/0.
<Sysname> system-view
[Sysname] interface t3 2/0
[Sysname-T3 2/0] clock master
controller t3
Syntax controller t3 interface-number
View System view
Parameter interface-number: CT3 interface number.
Description Use the controller t3 command to enter CT3 interface view.
Related command: display controller t3.
Example # Enter the view of interface T3 2/0.
<Sysname> system-view
[Sysname] controller t3 2/0
[Sysname-T3 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: Adopts no CRC.
Description Use the crc command to configure CRC mode for the serial interface formed on
CT3 interfaces.
Use the undo crc command to restore the default, that is, 16-bit CRC.
These two commands apply to serial interfaces formed on T3 channels, T1
channels, and the interfaces formed by binding slots of T1 channels.
Related command: t1 channel-set, t1 unframed, using (CT3 interface view).
