Configuring A Ct3 Interface In Ct3 Mode - H3C SR6602-X Configuration Manual

Step
5. (Optional.) Configure the
interface description.
6. Set the clock mode.
7. Set the cable length.
8. Set the framing format for the
CT3 interface.
9. (Optional.) Set the loopback
mode.
10. (Optional.) Configure alarm
signal detection/sending.
11. (Optional.) Configure FEAC
channel signal
detection/sending on the
CT3 interface.
12. (Optional.) Configure MDL
message detection/sending
on the CT3 interface.
13. (Optional.) Restore the
default settings for the CT3
interface.
14. (Optional.) Bring up the CT3
interface.
15. Return to system view.
16. Enter synchronous serial
interface view.
17. Set the CRC mode.

Configuring a CT3 interface in CT3 mode

When you change the interface state during the configuration, make sure you understand the
following information:
•
Shutting down or bringing up a CT3 interface also shuts down or brings up all its lines and serial
interfaces, including:
T1 lines demultiplexed from the CT3 interface.
Serial interfaces created for unframed T1 lines.
The serial interfaces created for channel sets on framed T1 lines.
•
Shutting down or bringing up a T1 line also shuts down or brings up the serial interface created
for it.

Remarks
By default, the description of an
interface is interface-name
Interface.
The default clock mode for the
CT3 interface is slave, which is
line clock.
The default is 14.9 meters (49
feet).
By default, the framing format on
the CT3 interface is C-bit.
By default, loopback is disabled.
By default, alarm signal detection
is enabled and alarm signal
sending is disabled.
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.
N/A
By default, a CT3 interface is up.
N/A
Make sure the synchronous serial
interface is the one created for the
CT3 interface.
The default is 16-bit CRC.
