14. Set the CRC mode.
crc { 16 | 32 | none } By default, 16-bit CRC is adopted.
Configuring a CE3 interface in CE3 mode
When you change the interface state during the configuration, make sure you understand the following
information:
• Shutting down or bringing up a CE3 interface also shuts down or brings up all its lines and serial
interfaces, including:
{ E1 lines demultiplexed from the CE3 interface.
{ Serial interfaces created for unframed E1 lines.
{ The serial interfaces created for channel sets on framed E1 lines.
• Shutting down or bringing up an E1 line also shuts down or brings up the serial interface created
for it.
• To shut down or bring up only the serial interface for an E3, unframed E1, or framed E1 channel,
use the shutdown or undo shutdown command in serial interface view.
To configure a CE3 interface in CE3 mode:
Step Command Remarks
1. Enter system view.
system-view
N/A
2. Enter CE3 interface view.
controller e3 interface-number N/A
3. Configure the interface to
operate in CE3 mode.
using ce3
The default operating mode is CE3
mode.
4. (Optional.) Set the operating
mode of an E1 line on the CE3
interface to unframed mode or
framed mode.
• Method 1:
Set the operating mode to
unframed (E1) mode:
e1 line-number unframed
• Method 2:
Set the operating mode to
framed (CE1) mode and
bundle timeslots on the CE1
interface:
a. (Optional) undo e1
line-number unframed
b. e1 line-number
channel-set set-number
timeslot-list list
By default:
• In method 1, the operating
mode is CE1.
• In method 2, the operating
mode is framed, and no
channel sets are created.
5. (Optional.) Configure the
interface description.
description text
By default, the description of an
interface is interface-name
Interface.
6. (Optional.) Configure the CE3
interface to perform BERT test,
and configure the CE3
interface to perform BERT test
on an E1 channel created on
the interface.
bert pattern { 2^7 | 2^11 | 2^15
| qrss } time number [ unframed ]
e1 line-number bert pattern { 2^11
| 2^15 | 2^20 | 2^23 | qrss }
time number [ unframed ]
By default, no BERT test is
performed.
