R0106-HP MSR Router Series Interface Configuration Guide(V7)

Step Command Remarks
12. (Optional.) Configure FEAC
channel signal
detection/sending on the CT3
interface.
• feac detect
• feac generate loopback
{ ds3-line | ds3-payload }
• feac generate { ds3-los |
ds3-ais | ds3-oof | ds3-idle |
ds3-eqptfail }
By default, FEAC channel signal
detection is enabled, but no FEAC
signals are sent.
13. (Optional.) Configure MDL
message detection/sending on
the CT3 interface.
mdl { data { eic string | fic string |
| gen-no string | lic string | pfi
string | port-no string | unit string }
| detect | generate { idle-signal |
path | test-signal } }
By default, MDL message detection
and sending are disabled and the
default MDL message information
applies.
14. (Optional.) Restore the default
settings for the CT3 interface.
default N/A
15. (Optional.) Bring up the CT3
interface.
undo shutdown
By default, a CT3 interface is up.
Use this command with caution,
because once an interface is shut
down, it stops operating.
16. Return to system view.
quit N/A
17. Enter synchronous serial
interface view of an interface
formed on a CT3 interface.
• interface serial
number/line-number:0
• interface serial
number/line-number:set-numb
er
N/A
18. Set the CRC mode.
crc { 16 | 32 | none } By default, 16-bit CRC is adopted.
Serial interfaces created on CT3 interfaces support the following protocols:
• Data link layer protocols, such as PPP and HDLC.
• Network layer protocol IP.
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.
• To shut down or bring up only the serial interface for a T3, unframed T1, or framed T1 channel, use
the shutdown or undo shutdown command in serial interface view.
