Displaying And Maintaining Ct3 Interfaces - H3C SR6600 Configuration Manual

Step
12. (Optional.) Configure FEAC
channel signal
detection/sending on the
CT3 interface.
13. (Optional.) Configure MDL
message detection/sending
on the CT3 interface.
14. (Optional.) Place a T1 line on
the far-end CT3 interface in a
loopback.
15. (Optional.) Set the FDL
format for a T1 channel.
16. (Optional.) Restore the
default settings for the CT3
interface.
17. (Optional.) Bring up the CT3
interface or a T1 line on the
interface.
18. Return to system view.
19. Enter synchronous serial
interface view.
20. Set the CRC mode.

Displaying and maintaining CT3 interfaces

Execute display commands in any view and reset commands in user view.
Task
Display CT3 interface or T1 line information.
Display the configuration and state of a serial
interface formed on a CT3 interface.
Display the state of a T1 line.

Remarks
By default, FEAC channel signal
detection is enabled, but no FEAC
signals are sent.
By default, MDL message
detection and sending are
disabled and the default MDL
message information applies.
By default, no loopback mode is
set.
By default, FDL is disabled.
This operation applies only to T1
channels that are formed on CT3
interfaces, operate in channelized
mode, and use ESF as the T1
framing format.
N/A
By default, all CT3 interfaces and
T1 lines are up.
N/A
Make sure the synchronous serial
interface is the one created for the
T1 line you want to configure.
The default is 16-bit CRC.
